Can I use FreeRTOS when using MVP?

[Martin KJELDSEN]

Sure. The two are not mutually exclusive. One is an RTOS the other is a software pattern.

I did PWM with DMA. Errors pop up:

../Core/Src/main.cpp:571:25: error: 'htim3' was not declared in this scope

../Core/Src/main.cpp:571:48: error: 'duty' was not declared in this scope

?

Nothing MVP is going on in main.cpp yet. You're referncing some symbols that aren't available. This is board bringup. You've defined a function Up() but you're using a reference to htim3 that isn't defined anywhere.

What made you write the code in this way? did you copy it from somewhere?

void Up(void){
	HAL_TIM_PWM_Start_DMA(&htim3, TIM_CHANNEL_1, &duty, 1);
}
