Resolved! How to access Bus voltage reading in motor control software

I'm using the STM32G431 MCU to run a BLDC motor with the middleware FOC code. I'd like to be able to report the bus voltage in the system but haven't been able to find the way to access the code. I found a procedure declared in bus_voltage_sensor.c, ...

Resolved! [STM32F7] Using DMA transfert with TIM1 and TIM8 in PWM generator

Hello,I search information on the managment of the DMA transfert to the timer.I use the TIM1 and TIM8 to generate 3 PWM output on each of them. The six output are synchronized.I want to use the DMA to update the timer value, rated on 28µs.I don't kno...

how does the divider work in PID tuning?

I am using NUCLEO-F303RE, X-NUCLEO-IHM08M1, MotorControl Workbench 5.4.4 and STM32CubeMX 5.5.0. I have managed to generate a project as position control and it seems to work fine however I am wondering if I can improve further the performance of the ...

Resolved! evspin32f0601s1 (6-step control in workbench)

I bought the evspin32f0601s1 board.In the data sheet"Sensored or sensorless 6-step algorithm"It is described like this...Is it not possible to select 6-step in the st motor control workbench?And since there is no detailed information about the workbe...

Resolved! [CRITICAL HW BUG + FIX] STEVAL SPIN3204 board: maximum motor current not reaching 16A as claimed

PCB layout of STEVAL STSPIN3204 board contais critical bug as explained in attached report which prevents the design to work up to claimed 16Arms. This bug creates extreme radiated emissions (affecting nearby instruments) and prevents the proper func...

Resolved! EVSPIN32F0251S1, in the schematic, what is the function of U3. When is it used.

USING st motor control workbench 5.45 with EVSPIN32F0251S1, when I start motor I get spped fault. why, how to fix. thank you.

How to read additional ADC channel in Motor Control MC SDK 5.4.4 (STSPIN32F0601)?

I am using MC SDK 5.4.4 to drive a PMSM motor using STSPIN32F0601. Now, I want to add a potentiometer to my system to sense different user selectable levels. Generally, in other appplications we can intialize the ADC and read the ADC converted values...

Pin state of STM32G431KBT in DFU boot mode

I build a custom board with the STM32G431KBT controller that drives a DC motor via a TI motor driver.When I put the board in boot mode it drives the motor at full speed.This only can happen when a combination of 4 pins is in a specific state.One PWM...

IHM08M1 with NUCLEO-H743ZI2 board in FOC mode.

Hi! I need to control a BLDC motor in FOC mode. I have a NUCLEO-H743ZI and IHM08M1, I know that they are not compatible with the ST morpho connector. But I decided to connect them manually with wires.On IHM08M1 board I removed capacitors C3, C5, C7, ...
