For STM32, there are two ways to reset the software: 1) Use the official software library The system reset function is directly provided in the stm32f10x_nvic.c file of the official software li...[Details]
The status of interrupts in developing embedded systems is absolutely unquestionable. In the era of C51 microcontrollers, there were only 5 interrupts, including 2 external interrupts, 2 timer/counte...[Details]
I recently upgraded MDK to V5.25 and found that there are many libraries in the Managing Run-Time Environment. Compared with the past, it is much better, from the bottom-level driver to the upper-le...[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]
1. Usage scenarios In the first case, when using a common STM32 delay function, similar to HAL_Delay(time), since this function uses a loop to judge and delay, when executing this function, the ent...[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]
