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

Device is protected
I'm sorry, I'm not a STM8 developerI just want to upgrade an RFID readerThe CPU is STM8S003F3The programmer is ST-LINK V2The connection is SWIMThe programmer is ST Visual ProgrammerIt gives me the error "The device is protected"Is there any way to er...
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...
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 ...
Resolved! Dangerous error causes fires and devastation!
Hi. I'm glad you're reading this, i hope you can help.Click-bait aside, i experience a nasty and unexpected behavior of external interrupts in a professional, industrial product designed around STM8AL318ATC.In short, there are 2 digital signals (from...
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_...
