stm32_graphics_display_drivers's Issues

Help with ILI9486 - SPI mode.

Hi!

I can use this library for comunicate stm32f103c8 with a SPI LCD 3.5" for RPi. My display is similar like that : "http://www.lcdwiki.com/3.5inch_RPi_Display ".
As i can see the driver is ili9486. I tryed it with an example with Standard Peripheral Library , but not HAL.
I followed all the steps in this instructions and compiling the code works well. But i cant see image. I change the pins, and the macros in "lcd_io_spi.h" but nothing...

Can you help me?

I use this guide shared in your website
(https://www.youtube.com/watch?v=4NZ1VwuQWhw)
stm32f103c8 (bluepill board) - st7735 spi driver

Great work !
Tks

Some define can not find out in std lib like SPI_SR_BSY_Pos SPI_SR_RXNE_Pos please teach me which file them included

Thx for your hard work，beyond all praise.

using LCD_IO_WriteCmd8MultipleData16 for each image row

Would it be possible to expose these functions:

ili9341_SetDisplayWindow(Xpos, Ypos, Xsize, Ysize);
LCD_IO_WriteCmd8MultipleData16(ILI9341_RAMWR, (uint16_t *)pData, Xsize * Ysize);

So it would be possible to send each row of image without calling ili9341_SetDisplayWindow?

ili9341_SetDisplayWindow(Xpos, Ypos, Xsize, Ysize);
for (int i = 0; i < image_height; i++)
{
  // read image line
  LCD_IO_WriteCmd8MultipleData16(ILI9341_RAMWR, (uint16_t *)pData, Xsize * Ysize);
}

Just interested to see would it improve performance. I am trying to make screen as fast as possible...

Horizontal display with good viewing angles - 480x272 SSD1963?

Hi, just wanted to ask if you know any horizontal display with good viewing angles?

I have bought this ILI9486 320x480 3.5inch_Arduino_Display-UNO but I think this display is not intended to be used in horizontal orientation 480x320, I was really disappointed, its horizontal viewing angles are horrible.

What about SSD1963 480x272? I think its for horizontal use, is there any plans to support its drivers?

SPI Reading Codes not working

Hi dear Roberto Benjami.
I used your codes.
I am using STM32F030C8T6 in SPI Mode and ili9341 Driver.
The answer of the codes used to read information from the LCD is always 0x0000. Like BSP_LCD_ReadID() or BSP_LCD_ReadPixel().

stm32f407ve LL spi possible?

Hi

Is it possible to drive my ILI9341 (DSO138) display on the STM32f407VET board (black)
via LL drivers without HAL using spi dma?

Or does this require heavy rewriting of your driver code to work with LL?

Image distortions on STMF407VE

Hi when I moved same code from STM32F091RC to STM32F407VE (changed driver to FSMC 8bit) I am getting strange image distortions. On STM32F091RC everything was working fine.
I am using ILI9486 driver. Tried no DMA but does not change images apear distorted.
Any ideas?

Touch xpt2046/ili9341

Hello Roberto, Thanks a lot for your excellent work. A time ago, I got from china, some recicled boards wich use Illi 9341, ads7846 and stm32f103vct6 and a 2.8 inch Lcd , but I didn´t get any information about firmware (It was for a cryolipolysis machine). Your firmware on the display is working excellent but when I tried to add ts functions I coudnt get to make it work. I have to say the ADS7846 isn´t conected to SPI port, so I had to use the configuration for SPI SOFTWARE. After try reading cordinates results on serial port, I realised that the firmware doesnt write the port and also cant get the coordinates. I wrote my own code and I discoverd that the problem is using bit masking for write/read ports.
Your code write in ts_xpt_2046.c
void TsWrite8(uint8_t d8)
{

GPIOX_ODR(TS_MOSI) = BITBAND_ACCESS(d8, 7);
TS_WRITE_CLK;
GPIOX_ODR(TS_MOSI) = BITBAND_ACCESS(d8, 6);
TS_WRITE_CLK;
GPIOX_ODR(TS_MOSI) = BITBAND_ACCESS(d8, 5);
TS_WRITE_CLK;
GPIOX_ODR(TS_MOSI) = BITBAND_ACCESS(d8, 4);
TS_WRITE_CLK;
GPIOX_ODR(TS_MOSI) = BITBAND_ACCESS(d8, 3);
TS_WRITE_CLK;
GPIOX_ODR(TS_MOSI) = BITBAND_ACCESS(d8, 2);
TS_WRITE_CLK;
GPIOX_ODR(TS_MOSI) = BITBAND_ACCESS(d8, 1);
TS_WRITE_CLK;
GPIOX_ODR(TS_MOSI) = BITBAND_ACCESS(d8, 0);
TS_WRITE_CLK;
}

I tried with that and I got values, but has too much noise, I would like use your code

unsigned char TCS_SPI_Read_Write(unsigned char DataByte)
{
unsigned char Bit,result = 0 ;
for (Bit = 0; Bit < 8; Bit++)
{
// Clock High(Prepared Write Data)
HAL_GPIO_WritePin(GPIOD, GPIO_PIN_15, GPIO_PIN_SET);
// Write Data to MOSI Pin : MSB First
if((DataByte & 0b10000000)== 0b10000000)//0x80)
{
// Set Bit Data(MOSI) = 1
HAL_GPIO_WritePin(GPIOD, GPIO_PIN_13, GPIO_PIN_SET);
}
else
{
// Reset Bit Data(MOSI) = 0
HAL_GPIO_WritePin(GPIOD, GPIO_PIN_13, GPIO_PIN_RESET);
}
// Clock Low(Strobe Data & Read)
HAL_GPIO_WritePin(GPIOD, GPIO_PIN_15, GPIO_PIN_RESET);
// Shift Next Bit Data
DataByte <<= 1;
// Read Data From MISO Pin
result <<= 1;
if ( HAL_GPIO_ReadPin(GPIOD, GPIO_PIN_11) == GPIO_PIN_SET)
{
result |= 0b00000001;//0x01;
} }
return (result);
}

Thanks again, regards from Argentina

Help for XPT2046 on ILI9486(SPI mode)

Hi.
ILI9488 (spi mode-DMA) works great on STM32F407VET6. I couldn't find any example related to XPT2046. I decided to do it myself. Many compilation errors occurred when I included the XPT2046 touchscreen. The problem appears in the file "stm32_adafruit_ts.c".
Where am I doing wrong?

SPFD5408/ILI932x

Namely, in fsmc mode 8bit with the SPFD 5408 controller, I can't get a display on the screen, only a white screen, no image. This controller in the sequence to write the index register does not need to write the higher byte, only the low uint8_t byte, could it be a problem or the speed of the transaction?
To be precise, the controller in that lcd has ID = 2053, but it works fine with drivers for ILI932x. It is otherwise a very common LCD Arduino shield.
Just one more observation that might help solve the problem:
At the moment when he needs to write something in GRAM, the screen is completely white, but in between for a moment color noise appears. That's why I thought that the problem might be with the speed of writing in GRAM.

FSMC changed RS line

I had to change the RS line in the FSMC driver to A17 (PD 12). But I can't find how I should change #define LCD_REGSELECT_BIT 6 to get the proper memory bank select address.
My question is how to get LCD_REGSELECT_BIT =" x " in a function of LCD RS select line ?

regards, freetoair.

ILI9488 Hardware SPI not working (but software mode works)

stm32_caplcd_test.zip

Hi RobertoBenjami!

I'm trying to use an ILI9488 screen and recently saw this library. It has been super helpful, thanks a lot for your effort!

However, I ran into an issue using hardware SPI. The whole project file is attached.

I set up the hardware SPI1 in CubeIDE and configured the lcd_io_spi.h, it will not work if I set the LCD_SPI to 1 (i.e. SPI1), however when I switch it to 0 and keep everything else, the code works.

I would really like to use hardware mode for DMA support. Could you help me to see whether I have done anything wrong during the configuration?

Best regards,
Desmond

LittleVGL compatibility?

Hello, is there, or have your tried your drivers in combination with LittleVGL (lvgl.io)?
Basically, it just needs a (callback) function to fill a certain area of the screen with a buffer (of color values).
And preferable via DMA.
Thanks!

STM32F091RC Nuclio - can it be that DMA interfare with CAN BUS?

Hi, your driver is working fine with STM32F091RC, but once I try to draw while also sending receiving CAN BUS messages MCU gets into infinite loop in WaitForDmaEnd, LCD_IO_DmaTransferStatus value seems to be 1.

Is my configuration wrong?

My configuration:

 #define LCD_SPI           2
 #define LCD_SPI_MODE      1
 #define LCD_SPI_SPD_WRITE 1
 #define LCD_SPI_SPD_READ  3
 #define LCD_SPI_AFR       0
 #define LCD_RST           B, 11  /* If not used leave it that way */
 #define LCD_RS            B, 14
 #define LCD_CS            B, 12
 #define LCD_SCK           B, 13
 #define LCD_MOSI          B, 15
 #define LCD_MISO          X, 0  /* If not used leave it that way */
 #define LCD_BL            X, 0  /* If not used leave it that way */
 #define LCD_BLON          0

 #define LCD_DMA_TXWAIT      0
 #define LCD_DMA_RX_BUFSIZE  256
 #define LCD_DMA_RX_BUFMODE  1

If I enable Software SPI everything works just drawing is much slower. How to use DMA SPI with CAN also?

Driver integration with STemWin library

Hello Roberto. First of all I want to thank you for sharing your drivers. They are really very useful.
At the moment I'm using the driver for ILI9486 with an F446RE nucleo board (8 bit parallel with Touch screen) and it works perfectly.
However, I cannot integrate your drivers with the STemWin library.
Could you help me?
Thanks again

To watch SWO i use STM32CubeProgrammer with SWV. I cannot understand why output is like this:

and why after 3 checked rectangles it does not show me TS_CINDEX values.

I've checked that longer SWO buffers works corrcectly.

animation question

Hi
Sorry, programming noob alert!
Not a bug, rather a programming question.
I connected the display to my blue pill via 8bit parallel and works so far.
How would one realize for example a smooth moving rectangle(w=40,h=40) from X0/Y0 to X0/Y200 ?
I tried with a simple for loop counting up to the screens height-rectangleSize, moving the rect step by step and after each step I cleared the screen with BSP_LCD_Clear(RGB888TORGB565(0,0,0)).
But clearing the screen like that is very time intensive and gives obviously not a smooth movement.

My next try was to move the rect and behind I move another rect that clears the previous rect with the background color. That gives me a nice smooth animation instead of clearing the whole screen every step.
Is that the right way? So how would you do that?

Touch XPT2046

Hello Roberto,

First of all, thank you for your work.
You really did a GREAT job with these graphical drivers.
I'm however facing a little problem.
I'm using a 3.5 touch panel, sporting ILI9488 and XPT2046.
I interfaced it with a NUCLEO-F411RE development board (STM32F411RE in LQPF64 package).
The panel shows the usual ILI9488 SDO problem, in which the line is never released and never goes tri-state.
So I decide to use two different SPI lines, one for the LCD (ILI9488), the other for the touchscreen (XPT2046).
I used the "stm32f4xx/cd_io_spi.x" driver, which works just fine (with the "LcdSpeedTest" app).
When I try to add the touchscreen support, however, I get errors.
I imported the "ts_xpt2046.x" files into the project.
Unfortunately, the compiler keep complaining that a "ts_drv" reference is missing, since it is not declared nor referenced in any place.
I think we need something like the "lcd_drv" defined in "ili9488" driver.
I know we need to write a xpt2046 driver, I will try to write it, but before, do you have something already done?
Thank you!

'GPIOX' undeclared (first use in this function); did you mean 'GPIOA'?

Thank you for the code. I've done everything like the video, but there is some errors in this file "lcd_io_gpio16.c".

For example, in line 73 (#define GPIOX_SET_(a, b) GPIO ## a ->BSRR = 1 << b), there is this error:

'GPIOX' undeclared (first use in this function); did you mean 'GPIOA'?

I've commented these 5 lines to see other possible errors. Now, there is an error in this file "lcd_io_gpio16.h".

In line 8 (#define LCD_CS F, 13), there is this error:

'F' undeclared (first use in this function)

Do you know what I've done wrong?

Thank you in advance.

		LCD_WR_DATA(0x01);   
		LCD_WR_DATA(0XDF); 			
	}
}

The LCD_Clear() like this:

void LCD_Clear(void)
{ 
	uint32_t i = 0;
	LCD_SetCursor(0,0);	
	LCD_WR_REG(0X2C);		
	for(i=0;i<320*480;i++)	
	{
		*(__IO uint16_t*) FSMC_DATA = LCD.BackColor;
	}
}
	
void LCD_SetCursor(uint16_t x, uint16_t y)
{
	LCD_WR_REG(0x2A); 							
	LCD_WR_DATA(x>>8);LCD_WR_DATA(x&0XFF); 	
	LCD_WR_DATA(0x01);  
	LCD_WR_DATA(0xDF); 	
	LCD_WR_REG(0x2B); 						
	LCD_WR_DATA(y>>8);LCD_WR_DATA(y&0XFF); 	
	LCD_WR_DATA(0x01);   
	LCD_WR_DATA(0xDF); 
}

Could you tell me what register i was missed? How can i check this issue?

Thank you very much!

ili9488 + stm32f103ret6

hi
thanks for your great work for beginners(as me!)
i am trying to run ili9488 on f103re(8 bit parallel) with your youtube film but no success
i think you have forgotten to add setup pin configurations (gpio output on video)
this is my setup
d0-d7 > pin c0 to c7
rd > pin c8
wr > pin c9
cs > pin c10
rs > pin c11
rst > pin c12
i set all pins as out put except c8 (it is input)
compile give me no error but no success in action
i use stm32cube ide in linuxmint

Please add support for display SSD1963

Hi, i'm trying to add support for display SSD1963 (800x480 7" display).
I've copied the initialization commands sequence from another library that is working, but i'm just getting the display to initialize, startup and show something (like clear screen and draw a cirle) display a blue rectangle in the center of the screen with some sorta of circle all messed up.
I have this display, so if you wanna try with my help to create this driver support, i'll be glad to contribute.

I attach here the code i've created for this display, if wanna check it:
ssd1963.zip

SPI DMA for STM32L4

I am delighted with your driver, everything is done very carefully. Tested F4, SPI + DMA, FSMC16 + DMA, ILI9341. No complaints, thank you very much. Also tested SPI on L4 (STM32L433, STM32F452), DMA does not work due to an error - the request channel is not taken into account. For definitions LCD_DMA_TX, LCD_DMA_RX there must be 4 parameters: DMA number, DMA channel, DMA request, DMA priority (similar to the L0 family).
For L4 I made the following modifications:

• used the lcd_io_spi.h file from L0;

• in the lcd_io_spi.c file definitions /* DMA */ copied from the file for L0;

• in the same file lcd_io_spi.c in the LCD_IO_Init () function added the following code:

  #if DMANUM(LCD_DMA_TX) > 0
  DMAX_CSELR(LCD_DMA_TX)->CSELR = (DMAX_CSELR(LCD_DMA_TX)->CSELR & ~(0xF << (4 * (DMACHN(LCD_DMA_TX) - 1)))) | DMAREQ(LCD_DMA_TX) << (4 * (DMACHN(LCD_DMA_TX) - 1));
  #endif
  #if DMANUM(LCD_DMA_RX) > 0
  DMAX_CSELR(LCD_DMA_RX)->CSELR = (DMAX_CSELR(LCD_DMA_RX)->CSELR & ~(0xF << (4 * (DMACHN(LCD_DMA_RX) - 1)))) | DMAREQ(LCD_DMA_RX) << (4 * (DMACHN(LCD_DMA_RX) - 1));
  #endif

The TX process is now running fine. The RX process has not been tested. The numbering of channels in L0 and L4 is 1...7, so -1 in the given code must be taken into account for L0 as well.
Please update your driver accordingly.

Driver for ST7796S

Can you add st7796s driver ? Thank you sir

Configurable TS pins

Hi, great job!
I recommend to pull out TS pins configuration to header file.
Not all LCD has XP/XM/YP/YM on data pins pre-configurated like it is done inside lib.
It's small change but very helpfull ;)

Whats the fastest way to draw? (ILI9341 spi dma)

Hi, I wanted to ask whats the fastest way to draw?
I noticed you are formatting whole BMP image when drawing text.
Whats the best size to send images? (having in mind that ram cant hold whole screen image)
Would you be interested in contributions for making font to support dynamic width per char and other changes in stm32_adafruit_lcd?

ILI9341 in SPI mode tested on L152RE

Hi,
Your README.md says "untested", but I tested your code on a L152RE board (Nucleo) in combination with an ILI9341 LCD, and this is working perfect (software SPI, hardware SPI & hardware SPI with DMA).
I used the STM32CubeIDE instead of TrueStudio, but your walk-through applied quite well on this IDE.
Thanks!

ILI9341 3.2inch TFT with XPT2046 Problem

Hi Roberto!
I use STM32F103C8T6 and ILI9341 display(SPI) with XPT2046, I tested that all functions can work except Display char function, I cannot display any char at the display, and the Char Test in appLcdSpeedTest is also doesn't work, it just display the black screen.

I tried to change the SPI Baud Rate but it just can control the LCD speed.

Can you tell me how to solve this problem?

Thank you!!

Hi,

I am working on display for electric motorcycle.

I have STM32F769i-Discovery and WF50DSYA3MNN0.
This display has ILI9881C driver. I have connected display and kit through converter board.

I find out your drivers for ili9486, ili9488,...
I would to ask, if there is posibilty modify this code and use it for ILI9881C driver.

Thanks for your advice.

ILI9488 gpio8 mirror issue

Hello dear Benjami,

I am working on ILI9488 integration using gpio8 interface.

The mirror problem occurs when I print text on the screen. How can I solve this problem?

My configuration
#define ILI9488_INTERFACE 1
#define ILI9488_ORIENTATION 3

When I set the configuration like this
#define ILI9488_INTERFACE 0
#define ILI9488_ORIENTATION 3
problem is solving. But I am not using SPI mode and I observed SPI mode is slower than gpio8.

3.5inch Arduino Display-Mega2560?

Hi, I want to power this 3.5inch Arduino Display-Mega2560 from STM32F407VE, but cant find RD and backlight pin on the display? Also it writes that its 5V, but in your PDF i see that you use 3.3V?
How do I connect this display?

Add font?

Hi. Thanks for your hard work on this library. I want to ask on how can we add a custom font and font size.

Touch support for ili9341?

It seems there is no touch support for ili9341. I tried to use appPaint with ili9341 and found there are no ts_drv and ts_cindex definitions.

ILI9486 3.5 inch TFT Problem

My board is STM32F103C8T6, I use the ILI9341 LCD driver to control the ILI9341 3.5(480*320) touched TFT, but it can not display anything.

Unexpectedly, I use the ILI9486 driver to control the ILI9341, the display function is effective!!, but the touch function does not work.

I used Arduino to test whether the LCD can be touched, I'm sure it can detect the x y coordinates.

Could you help me to solve my problem?

Thank you very much!!
