The practical limit on the number of PRU channels is the available PRU
memory and how long it takes the PRU to process each channel.
The MAX_CHAN value comes from the software pwm driver and is not
currently used. It is somewhat misnamed, as it does not represent the
number of PWM channels, but
I've got a Beagleboard x15 for which there's no uio driver setup, only ti's
remoteproc_pruss, thus the existing HAL_PRU_GENERIC driver won't work as
is. I'm planning to use py-uio (
https://groups.google.com/forum/#!topic/beagleboard-x15/MfB-GMl0UYA ) to
get a UIO for the pru. I thought that I
In general, the *.p files are PRU assembly code and you will need to use
them (or the assembled PRU binary file). The *.c files are the HAL
driver files used to talk to the PRU, you will likely need to replicate
this functionality in Python if you want to talk directly to the PRU
from Python.
Hi!
I'm looking to into the source code of hal_pru_generic to modify it to load
the pru code using python with py-uio (so it can work on BBX15), but I'm
having some trouble understanding the source code of the pru
driver/component. My plan is to first make it work with step/dir.
First: the
Please keep replies on-list.

hi everyone,
i am studying machinekit, in particular on the BeagleBone, i' ve found that
in the CRAMPS.hal file it loads a file for the PRU called pru_generic.bin.
for what i've been able to see, the pru now controls stepgen and pwm
generation.
is there a manual for this libraries for the PRU?
