Attempting to run littleVGL demos on Raspberry Pi 3 with the ‘official’ 7" touchscreen display. Struggling with touchscreen. Also uncertain of how SDL\terminal text input relate to LittleVGL.
What MCU/Processor/Board and compiler are you using?
Raspberry Pi 3
What do you want to achieve?
Use LittleVGL on a framebuffer from a RaspberryPi with the official 7" touchscreen device.
What have you tried so far?
As far as I can tell, I have exhausted Google searches and the forum. I have found several relevant posts here, and a few web pages via google. Using this info I have been able to get the screen working at the correct resolution and compile. However I havent been able to get mouse, keyboard or touchscreen input to work.
Some info came from here: http://www.vk3erw.com/index.php/16-software/63-raspberry-pi-official-7-touchscreen-and-littlevgl
One initial confusion I am having is that many examples reference
indev_drv.read = evdev_read;, but the compiler complains. Is indev_drv.read_cb a new version of the method everyone is using in the example code? Is there a better driver to be using for this device? It shows up using evtest. It works fine on /dev/input/event0
I am also trying to figure out how to compile with mouse or keyboard support, though my final application will just be touchscreen. I have both enabled in lv_drv_conf.h, I think, however neither work when I run the program. When I type on a keyboard, it just shows text on the screen. and does not seem to respond
Any advice would be great!
I will post code if it seems helpful. Right now it wont let me attach.
