I'll take up this one

anujdeshpande commented 10 years ago

The current status of PRU on BBB is that one is required to write assembly code for it. A C compiler is almost ready for release.

@mranostay's recent blog post says that the compiler is to be released soon. I'll try posting an update on the release date

BTW https://github.com/pantoniou/testpru/ has a PWM remoteproc firmware already @pantoniou

The tasks that this issue should address are the following:

Both tasks are expected to be coded in C using the new/upcoming C compiler for the PRU.

For the second task the work of @greghaynes at the https://github.com/greghaynes/BeagleDrone project could be useful.

greghaynes commented 10 years ago

Wow, looks like fun. Im not sure if I can be of help with the PRUSS specific bits, but im more than happy to help with AHRS code.

greghaynes commented 10 years ago

Actually, after doing a bit of digging, I might be able to help a bit more than I thought with PRUSS.

http://elinux.org/Ti_AM33XX_PRUSSv2 seems to have some good references.

@greghaynes sounds great to have your around. Really interesting your approach at https://github.com/greghaynes/BeagleDrone, what hardware are you using to test the performance of BeagleDrone? Maybe i could give it a try with Erle.

@jadonk is there any official date for the release of the C compiler for the PRU?

greghaynes commented 10 years ago

Ive been building it up on a hoverthings flip frame and 690kv multistar motors, although it still has a bit to go until the code is ready for flight. Currently still working on getting the control + model code built up.

Also very interested in this PRU compiler :)

vmayoral commented 10 years ago

Library for PRU under development here.

jadonk commented 10 years ago

No official date yet. E-mail me to get access to the Beta. Every time I ask, I hear the public release is about a month away. That has been true for at least 6 months now.
