CCS/BOOSTXL-DRV8305EVM: Using DRV8305 without SPI...

Part Number: BOOSTXL-DRV8305EVM

Tool/software: Code Composer Studio

Hi all,

a simple question. I'm using BOOSTXL-DRV8305EVM and LAUNCHPAD F28069M.

Assuming that the default DRV8305 values ​​are suitable for my project, can I use it without SPI com but only setting EN_GATE gpio in the MCU (All other signals needed are connected: INHA, INHB...GH, SH, SL...SN...etc)?

I'm trying to modify motorware (lab4a) to goal this, but I've some trouble with "hal.c" mods.

When I try to start the motor identification,
- Set the variable “gMotorVars.Flag_enableSys” equal to 1. Ok.
- Set the variable “gMotorVars.Flag_Run_Identify” equal to 1. Ok for the first 3/4 seconds, after firmware goes to "onLine" status nFAULT led turn on. The firmware report no error conditions but I've seen that with nFAULT set, ADC appears to read zero (...the voltmeter instead reads 36V)...

Anyone can help me?

Thank in advance.
