sdcc support for standard peripheral library?

The standard library for stm8 can only use Cosmic, Raisonance and IAR compilers, which are all either non-free or limited in some way or another. Is there a plan to include support for sdcc (or at least a way to use it)?

how to measure run time?

need to wait for GPIO configure?

GPIO_Init(GPIOD, R4_GPIO_PINS, GPIO_Mode_In_FL_No_IT); GPIO_Init(GPIOD, R6_GPIO_PINS, GPIO_Mode_In_FL_No_IT); delay_ms(1); DOes gpio configure need to wait for completion?

Does anyone have a problem writing to Eeprom? When I try to write say a '0x80, a '0x3f' is reported as written So I stored my data as 4 bit nybbles, , which works (I'm using the discovery Board.) Russ

Input Capture using timers.

HiI'm working on a BLDC Motor control project using STM8S Discovery Board (STM8S 105C6T6 MCU). I need to read the hall sensor inputs from my motor onto the three channels of TIM 2. So I thought of getting acquainted with the mechanism of input captur...

hi all i am new to stm8s ,i am trying to learn about timers in stm8s,i have one doubt to how to calcualte prescalar value.could somebody help me to calculate the prescalar value??

What is the sampling rate in adc??

I have some confusion about sampling rate in adc,in data sheet it conversion time takes 14 clock cycles, then i am using internal oscillator 16mhz and prescalar selection is 8 and i get conversation time is 3.5micro seconds,i want know about exactly ...

Hi All, I am new to STM8S and not yet that good at microcontroller programming in general. I am trying to learn about timers/counters in microcontrollers. I wrote following code to toggle an LED connected at PD1 pin in each second.

#include <stdint.h>#include<iostm8s.h>void main(void){         TIM2_PSCR = 0b00000111;  TIM2_EGR= 0x01; TIM1_CR1 = 0x01;    PD_DDR = 0x01; PD_CR1 = 0x01; while(1) { if ( ( ((uint16_t)TIM2_CNTRH << 8) + (uint16_t)TIM2_CNTRL ) >= 15625 )  { TIM2_...
