BBB PRU Code

Hi Maciej,

I've been looking at your DMA code for the BBB. I'm starting a project using the BBB and an ADC to log minutes worth of data and may try to leverage your code to hopefully save a PRU. I also need to write some slave serial interfaces (I2C and SPI) which looks like I will need to bit-bang in the PRU. I think I saw somewhere that you might have done this as well. If so, have you shared that code? Did you write it in C or did you have to do it directly in assembly?

Thanks! Dave

Hi, unfortunately I haven't done any bit-banged serial interfaces, you must have seen it somwhere else. I only know that there is SPI and I2C master implemetation in this GSoC project: https://github.com/chanakya-vc/PRU-I2C_SPI_master . It was done in C.
