Hello All,
I have a DRV8313EVM, using the software I have made my motor move. Now I want to move onto the next step.
Reading document SLAA503 which I am unsure if it still relevant, I assume so, it discusses closed/open loop methods. I got the relevant source from SLAA503 which gives a closed loop example.
As a demonstration, I want to use this firmware on the DRV8313 and want to modify it to make the motor go forwards then go backwards without any input from external sources.
Firstly, I assume there is not any technical limitation to do this and I assume that I can open J2 which will allow me to upload the firmware and debug.
Just some questions:
1) Once I upload the custom firmware, is the software still usable? I think that the software is un-usable if I have read page 14 of SLVU815 correctly. It refers to downloading "DRV8313_Release" as the user experience code
- On page 14 in slvu815 it gives a link ti.com/tool/drv8313evm to but the mentioned firmware I can't seem to locate on that page
2) If 1 is true, how to revert back to the control software becomes operational again?
3) I have J2 in place and Energia seems to see the on board MSP430, I haven't yet tried to upload. Have I misunderstood a requirement for J2? Do I need to touch it? CCS says No USB FET found but I have not tried to debug this message yet.
I've dropped myself in at the deep end here a bit, this is my first time attempting to do this kind of task so I've probably got my wires crossed in more than a few places.
Thanks for your time
Adam
