I am using stm32f107, and I want to use TIM1's 1 channel comparison to trigger AD conversion, but the PHY external to my chip also wants to use TIM1's 1 channel pin PA8. So, I just want TIM to trigger...
Some commonly used conversion tool functions in C language!
1. Convert string to hexadecimal
Code implementation:void StrToHex(char *pbDest, char *pbSrc, int nLen){char h1,h2;char s1,s2;int i;for (i=0...
I recently used a 5739 development board and tried a simple AD program. I did not set the clock and used an oscilloscope and the AD sampling period formula to deduce that the system clock was 1 MHz. I...
I am a hardware novice. I need to use an MCU and FLASH. The operating voltage of the MCU is 2.5V, ranging from 2.375 V to 2.625 V. The operating voltage of the FLASH is 2.7 V to 3.6 V. Do I have to us...
