I am currently working on a water temperature control system that requires a relay, but I don't know which model to use. Can anyone with experience give me some advice? Thank you....
If the voltage corresponding to the an0 port of the external 500V is 1V, if the voltage reference is 5V and ad is 10 bits, then its accuracy is 500V/(1024/5), right? If I amplify the 1V voltage sent t...
In the actual project development process, it is common to encounter modifications to the hardware circuit, and then the modified part requires the modification of the driver. Thinking about the comi...[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]
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]
