I would like to ask, after the serial port of stm32 is configured, how to write the interrupt service function? In addition to the initialization configuration, do I need other...
When designing an inflator test system, users should be aware that air bag inflators are explosive and therefore dangerous. Even if the test system is designed with adequate safeguards, a defective de...

1. Problem When developing STM32 with IAR, I found that I could not print floating point numbers by redirecting printf to the serial port. The code is as follows: The output is as follows: It can...[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]
