Resolved! How to phase shift two complementary PWM signal based on some internal TIMER event?
I am using STM32F051R8T6. My application is to drive a full bridge configuration, for which I require two pair of complementary PWM signals with dead time insertion. So far I have been able to achieve this using two channles of a timer( CH1-CH1N and ...
Interfacing between SMT32F and ST L6206
Previously I've designed a motordriver based on an STM32F303 and an ST L6206 Dual Full Bridge driver. I've had some issues with the interfacing between the MCU and the bridge driver, because the MCU works on 3V3 and the bridge driver works on 5V. So ...
UART not working on STM32F4 when GCC compiler is in O0 (None) optimization
In the last week I had to debug my MODBUS RTU slave application on my custom board for a communication issue on my RS485 network.My board is based on the STM32F411VET6 mcu and I developed my application with STM32CubeMX v5.0.0 and STM32F4 Firmware Pa...
Problem with WiFi Connection in board B-L475E-IoT01A2
I have purchased a B-L475E-IoT01A2 board that WiFi connection works well in the company. But the problem is that when I take this board home and test it, it doesn't connect to Wifi. It should be noted that in both cases, I test this board with my mob...
