esp-i2c-oled's Issues

Cannot access top area of oled display

I have one of these two color 128x64 oled displays: http://www.aliexpress.com/snapshot/6527585548.html

When I used ug8lib with an arduino, the top area which is yellow was accessed just by writing to the first few rows of the display. However with the ESP-I2C-OLED library, writing to position 0,0 seems to start in the blue section and the yellow top section is inaccessible.

As far as I understood it, the display is just a regular 128x64 monochrome display where the first 10 rows or so happen to be yellow instead of blue. Now sure why the library seems to think row 0 starts in the blue area.

Any ideas?

Hi, do you have plan to port u8glib to rtos-sdk

Hi, do you have plan to port u8glib to rtos-sdk. Thank you :)

Port of ESP-I2C-OLED

Hello Baoshi,

Did you have an example code for esp-open-rtos ?
https://github.com/SuperHouse/esp-open-rtos

If not, did you think it will be simple to port your code to esp-open-rtos ?

Best Regards,
Yann

Issue with I2c address

Hello, first of all thank you for your work.

I am having issues tho, I have it all compiled and flashed to my ESP but I am not able to show anything on my screen.

I am only using 1 screen which is Chinese SSD1306 version.

http://www.aliexpress.com/item/Free-shipping-1Pcs-128X64-OLED-LCD-LED-Display-Module-For-Arduino-0-96-I2C-IIC-SPI/2036109567.html

I have updated the i2c.c & ssd1306_i2c.c as you mentioned and changed the pins ( I am using pin 2 & 14 )

When I press init i get failed message & by debugging it seems failing in the i2c_write(ctx->address) part as it seems always coming with false.

Do i have to change this address based on my oled? 0x3c, 0x3d, etc

Can you please help me in figuring out this issue.

Thanks.
Sameh
