Why is heating up L6230 chip (on IHM07M1 expansion board)

I have a Nucleo-F302R8 board with X-Nucleo-IHM07M1 motor driver.When I run the motor (using my sensorless algorithm, PWM frequency is 20kHz) the L6230 chip is started to heat up and the temperature of the chip has very fast increased.In the L6230 dat...

the F302 project example of X-CUBE-SPN8 doesn't work

Dear I try to flash the example image which is located at the following path"STM32CubeExpansion_SPN8_V1.0.1\Projects\Multi\Examples\MotorControl\Src"to development board and using six-step to start motorbut the motor doesn't startup , check the failu...

STEVAL-ESC001V1 UART and JTAG Hardware Requirements

For this EVAL board, I see that there are 2 headers, one for JTAG [SWD] and one for Serial [UART] communications. It appears that these are just the raw digital 3.3 V logical connections from the MPU itself.However, there is not a single example sch...

POWER AND ENERGY value from STPM32

Hello,I am using STPM32 to monitor the voltage and current. When I refer the datasheet of STPM32 it shows we can directly get the power and energy value from STPM32. I am using STM32F429 as my MCU and using UART communication with STPM32. Please tell...

I want to know solution for end of charging in STEVAL-ISB044V1 board.

I have STEVAL-ISB044V1 board. I replaced new stwbc-ep digital controller and load program. I put smart phone for charging and after fully charged board continuously transmit power & green LED is blinking.So how to troubleshoot and solve this problem ...

STM3240G EVAL + STEVAL-IHM023V3 didn't work.

Hi everyone.I want to control PMSM using STM3240G and STEVAL-IHM023V3 power board. When I test with Motor Profile Tool, motor working correctly. But when I use Motor Work Bench to generate code and down upto STM3240G, motor didn't work. It's seem lik...

How to reduce the zero current offset reading from one of the channel of STPM33?

How to reduce the zero current offset reading from one of the channel of STPM33?Hi, I am using STPM33 for energy monitering. I have 2 STPM33 in my design and hence there are 4 current sense channels where I use shunt resistors for sensing. The proble...
