Pull in the tested tesla::GateDriver from commit bc109b82 of the c2000-inverter project for the Tesla Model 3 inverter native. This targets the STGAP1AS but this appears to be identical to the STGAP1BS from a programming perspective. A simple TeslaModel3 class is created to initialise and poll the operation of the gate driver. The Tesla Model 3 inverter board is identified automatically via the expected resistor divider network. The GPIO allocation for the gate driver is a placeholder only and will need further elaboration. Tests: - Core gate driver has been tested with HV on an original Tesla Model 3 inverter with TI C2000 MCU and open-loop PWM generation. No faults experienced in normal operation. Faults trip with incorrect PWM generation (dead-time, deliberate IO glitches, etc). - STM32 code compile tested only.

Thanks Dave. Before merging, do you understand why the test fails? |
|
Found it, I introduced the problem |
|
Sorry, I should have mentioned the failure in the PR. I didn't want to muddy the waters with an MG related fix. |
|
No worries. It's still not going through. Doesn't seem to build the libopeninv tests and consequently goes "file not found" when trying to run it |
|
I see. It looks like libopeninv out of date compared to stm32-sine. Probably down to my changes to both landing about the time Damien was branching for his MG changes. An uptick to libopeninv should fix it. |
