Hi all, I am trying to use the PRUs for real time data acquisition on the Beaglebone black (Linux debian 4.9.45-ti-r57). I have set up the PRU with remoteproc and RPMsg; everything is working fine. The first time, I successfully captured data with the PRU using the SPI protocol and bit banging, and I have sent them to the ARM with RPMsg.
Now I want to do the same thing using the I2C protocol, which left me with some questions: - Is it possible to use the on-board I2C bus with the PRUs? - If not, I will enable the pull-up resistor on a GPIO pins using a custom device tree. But after that, I do not really understand how I can read and write the SDA line for I2C? (Contrary to the SPI protocol, I won't have Data In and Data out lines but only one SDA line). My final goal will be to use the on-board ADC. There is already a very interesting project PRUADC that captures data using an external ADC. I would like to use the on-board ADC, is there any way to do it ? (I am not afraid of going into complex stuff).
