My board is STM32F103VE. I want to use the timer to count external pulses. Unfortunately, all the default ETRs of the IO are occupied by the peripherals of the board (sweating). I tried two methods:1
[code]void DelayUsx2(unsigned int t) { while(--t); }[/code]This is the code I wrote, but after setting the frequency of KEIL to 12Mhz, every time t decreases by 1, the time consumed is 8us. Its assemb
Comparison of DSP Processors and General-Purpose Processors Consider an example of digital signal processing, such as a finite impulse response (FIR) filter. In mathematical terms, an FIR filter is a
In order to prevent some variables in the program from being reinitialized after the watchdog is reset, I defined some variables as __no_init. As a result, after the watchdog is reset, the variable is
