Hi team,I have an STM32MP157 board with a Cortex-M4 processor. I have a simple task, which is to toggle the GPIO at maximum speed with accuracy, ensuring that the clock width does not vary.The maximum toggle speed we require is approximately 15ns bet...

Hello Everyone,I have STM32MP157F-DK2 board has an ARM Cortex-M4 chip that supports a frequency range of approx 209MHz. It takes about minimum 3.02 microseconds (Attached Screenshot) to achieve 40 clock pulses on this board. I also tried the STM32 Nu...

Hello @everyoneI have a OSD32MP1-BRK mpu board. I want to test maximum gpio toggle speed. Currently i used libgpio and using this code i achieved 4.1 us (microsecond) between rising and falling edge of pulses.This is too slow as per our requirement. ...

What is the purpose of using 100% of the Cortex-M4 CPU to toggle a simple GPIO ? Ans: Actually we are developing a device, where we have required to run multiple signals at a time to get proper result. I am sharing our signals screenshot. please see ...

Yes, I agree. As mentioned earlier, for STM32M7, I used Keil to achieve ~15 ns. However, when using the same controller in Cube IDE, the output differs, ranging from ~45 to 60 ns.

Hi @PatrickF ,I have installed STM32CubeIDE on my Ubuntu system. I selected the MPU and used the UI to select pin PD15 as a GPIO output, and I assigned the pin name "LED_1" before generating the code. However, in the main.h file, the pin number is no...
