What is better "Direct Resistor access or using Library" Hi all,from last 8 yrs i am writing programs for microcontrollers (mostly project on microchip, st) 8 bit/ 32 bit.i always write programs by writing directly to the registers. i never used any library like SPL, HAL, LL doesn't matter how long the code is i always directly write to registers .what is better way writing directly to registers or using any library by future prospective of my carrer.i wrote something like this.////////////////////////////////////////////////////////////////////#include "stm32f0xx.h"#include "stm32f030x8.h"void GPIO_Init(void);void ADC_Init(void);void TIM3_Init(void);void delay(void);unsigned int i=0,j=0,count = 0, data[10],avg = 0,diff=0,run_curr= 0,last_curr= 0,stability=0,FB=0,out_curr=0,aux_out_curr=0,last_out_curr=0,duty_cycle=0;unsigned long input=0,k=0;int read=5;int main(){ /****start PLL setting for system clock at 48Mhz using 8Mhz HSI****/ RCC->CFGR |= ((1<<19)|(1<<21)); // PLL Multification factor = 12 RCC->CFGR |= (1<<1);
