Hi Maksym,
You could reference the sensored and sensorless code examples in the reference designs:
Sensored trapezoidal - https://www.ti.com/tool/TIDA-010056
Sensorless trapezoidal - https://www.ti.com/tool/TIDA-010031
The sensorless trapezoidal uses ADCs…
Hi Nimesh, The firmware for the MSP430F5529 that is on the BOOSTXL-DRV8320H EVM page supports the application GUI and uses a protocol that make it difficult to run with using only CCS.
We recommend writing a simple sensored or sensorless trapezoidal FW…
Hi Bhuvaneshwaran,
I would not recommend trying to depend on running the GUI on a custom DRV8343-Q1 PCB board.
The GUI application firmware depends on multiple protocols specifically designed for identifying EVM boards. I am not sure how this is implemented…
Hi Florian,
DRV832x GUI is created externally, we don't have GUI javascript code.
" DRV832X_MSP430F5529_Trapezoidal_Sensored_BLDC" implements sensored trap code, but there is a lot of "extra layers" due to communication with the GUI and JSON protocol…
Hi Bhuvaneshwaran, Unfortunately I am not familiar with the CCS IDE firmware because it was written by a 3rd party and implements an "MDBU protocol" that is designed to be compatible with the GUI. I don't know if the firmware is intended to be…
Hi Julien,
Have you seen this reference design: https://www.ti.com/tool/TIDA-010031 ? It uses a different part in the DRV832x family.
DRV832x does not control the motor speed itself, it is only a gate driver. A system MCU is needed to perform speed control…
Hello Peter,
When you change the IDRIVE setting through the register, the change takes a little while to take effect, generally <100us.
Please see below for some introductory slides for DRV832x

Thanks,
Matt
Hello Kai,
Please find responses below.
The time is about the RL circuit, 1. could I estimate the time by the time constant of the RL circuit?
You could use that method.

Could you help to check the formula is ok or not? and any other I need to notice…
Hi Ella,
We have some TI design for motor control as the below:
https://www.ti.com/tool/TIDA-010031

And is there some details about this project? or some specific requirements?
Thanks!
Best Regards

Hi DRV experts,
I'm supporting a customer using our TIDA-010031 reference design that seems to be based on code from the BOOSTXL-DRV8320H evaluation…
