I received my DragonBoard410C a few days ago, following the guide LinuxUserGuide I installed Linux and also programmed the 3 applications successfully. At the moment I know how to use the user LEDs and the GPIOs.
Now I would like to use the I2C. Where I can find documentation to make a program for I2C peripheral in the same way (programming in a host PC with my IDE and the cross compile tool-chain) as I did for LED and GPIOs? I mean, I would like to understand the files of the different peripherals (allocated in /sys/class) in order to create programs for interface with SPI, I2C, etc… devices
I have taken a look at the Qualcomm document: Peripherals Programming Guide Linux Android from the developer Qualcomm web page. But i find it’s a different way of programming these peripherals. Am I right?
So I would find so helpful documentation explaining how to use the low-speed port SPI, I2C, UART, etc…
Thank you so much guys!
