bb-cp's Issues
Use VFB for "headless" Opi0 and NanopiDuo?
Since Orange Pi Armbian (20.05? Kernel 5.4.x) has basically made TV-out's Framebuffer impossible to activate now, (also Notro's FBTFT is getting more difficult to work with because the DTB instructions are getting unwieldy, not to mention it's been "orphaned" in the mainline kernels) CVBS-only SBCs like OpiZero and NanoDuo are almost out of luck in using SPI LCDs.
However, if we compile our own customized kernels, could we activate the Virtual framebuffer (VFB) and use BB-CP from that frame buffer to the ili9341? The default resolution seems to be 640x480, and if I'm not mistaken BB-CP can reduce resolution from 640x480@16bpp?
I know this circumvents the Mali400 video processor in the h3/h2+, but it's better than nothing right now... unless someone knows of a recent distro that still maintains CVBS out?
Add support for signal handling
Request to support signal handling. This would allow the application (launched during boot) to be cleanly closed if needed.
Currently applications exits and error message is printed
DATECODE sigHandler: Unhandled signal 2, terminating
Adding bbcp from startup and available for Retropie
Hi @bitbank2 ,
Thanks for pointing me to BB-CP yesterday. I'm able to have it working from the command line, no problem at all.
I've added this line to /etc/rc.local:
sudo /home/pi/BB-CP/bbcp --spi_bus 0 --background --flip
But it freezes the startup (somewhere around the Samba SMB setup). Have I missed something?
Thanks!
Run at startup?
Hi(again :P), i have manged to get the display working it was just a matter of recompiling :P but now i am stuck at launching it at boot :(
i added this at /etc/rc.local
sudo /boot/disp/BB-CP-master/bbcp --spi_bus 0 --lcd_dc 18--lcd_rst 22 spi_freq 46000000 --flip
it does show me whatever it is on the console but only that frame like once :P
Confused?
How can i install this?
LCD_ORIENTATION_LANDSCAPE ???
BB-CP is using the undefined LCD_ORIENTATION_LANDSCAPE:
main.c: In function ‘InitDisplay’:
main.c:277:23: error: ‘LCD_ORIENTATION_LANDSCAPE’ undeclared (first use in this function)
spilcdSetOrientation(LCD_ORIENTATION_LANDSCAPE);
^~~~~~~~~~~~~~~~~~~~~~~~~
Where in spi_lcd only the following are defined:
spi_lcd.h:#define LCD_ORIENTATION_NATIVE 1
spi_lcd.h:#define LCD_ORIENTATION_ROTATED 2
Implment using the gpiod userspace?
Any chance to implement using the new standard libgpiod interface?
Attempting to get working with Waveshare 3.5 480x320 + OrangePiPCPlus
Hi there ;
a few things are not evident from the readme
- Is the fbtft module required to be loaded or unloaded
- The GPIO definitions refer to which allocation - sysfs is deprecated ; and I am using gpiod formatting (which provides block access). Sysfs is still there for the time-being I compiled with the gpiogeneric define for the SPI_LCD part - was this the right one to use as none of the other options seem available for sunxi/h3 SoC's?
- I usually using the following init for the fbtft driver module options
`root@ruao01:~/SPI_LCD/pigpio#
cat /etc/modprobe.d/fbtft.conf
options fbtft_device rotate=90 name=piscreen speed=16000000 gpios=reset:2,dc:71 txbuflen=32768 fps=25`
Which I translated as:
`root@ruao01:~/SPI_LCD/BB-CP#
./bbcp --spi_bus 0 --spi_freq 16000000 --lcd_rst 7 --lcd_dc 166`
But I get :
`root@ruao01:~/SPI_LCD/BB-CP#
>
> ./bbcp --spi_bus 0 --spi_freq 16000000 --lcd_rst 7 --lcd_dc 166
> Error setting SPI mode
> Error setting SPI speed
> Failed to open the SPI bus
> Error initializing the LCD/display`
>
As the result when trying to launch
- The bbcp program assumes that fb0 is the drm/hdmi output - but in the case where ONLY the spi screen is connected this is not a valid assumption. Currently I have to plug an HDMI 'dummy' capture card in at boot to enumerate correctly. It would probably be useful to accept a mirror --from --to option.

NanoPi Duo2 Pins Mapping
Hey!
Great work on this by the way.
I am trying to get this working on a NanoPi Duo2 but I cant seem to get them right, I looked at your mapping table in the spi_lcd.c file, chose NanoPi Duo2 as that has the same GPIO Pin out.
Any help where to map the final 2 pins of DC/X and Reset would be most helpful.
Thanks in advance.
bbcp prints help when called with no parameters
Since all parameters are same as default for my setup, there is no need to pass parameters. BB-CP prints help and exits.
Suggested solution would be to follow Linux standard and print help only with '-h' or '--help' options.
Segmentation fault
I have Segmentation fault error running in orange pi zero.

Please add fbtft bgr=1 option
All the blue colors are orange in OrangePiZero when using sudo ./bbcp --lcd_led 12 --spi_bus 1. I know that this is an orange pi :-)
Notro's fbtft supports an option bgr=1 to "flip" the blue colors back from orange/red. Without this option the blue colors are all red on the screen. This is what appears to be missing in the bbcp command. Could you please add this option or provide some hints on how to add this? Thanks.
How to get this working with Waveshare 240x240
Please help me! I a was wondering how to get this working with 240x240 Waveshare hat on Armbian? Please tell, I am getting pretty desperate trying to get it to work! Also, I am using a Banana Pi Zero
