In the actual project development process, hardware circuits often need to be modified, and the modified parts need to modify the driver. Thinking about the coming and going of such requirements is t...[Details]
The program got stuck during LCD initialization. Through hardware debugging, it was found that it was stuck in the Delay_ms() function. Going to the definition, it was found to be a macro definition ...[Details]
Using Systick timer to achieve delay 1. SysTick timer characteristics The SysTick timer is a 24-bit down counter, that is, when vlue is decremented to 0, an interrupt is triggered and the load va...[Details]
The day before yesterday, I learned about STM's Systick and found it quite useful for precise timing. When I used CVAVR before, I found that the delay.h in it was very useful. So, I used STM32's...[Details]
Because the STM32 HAL library only has millisecond-level delay for HAl_Delay(), in order to achieve accurate microsecond-level delay, Systick has to be modified. However, since it is used internally ...[Details]
