Discuss STM8 microcontrollers, including SWIM, USART configurations, RTC usage, ADC issues, and debugging.
Posted on February 06, 2018 at 19:44For an embedded project with micro STM8, would be very useful to me to have the mathematical formula to calculate the 'timestamp' (epoch) in 'C' without using libraries because, unlike the STM32, for this family ...
Posted on January 25, 2018 at 11:06Hello, I'm using STM8L052R8(64KBytes ROM, 4KBytes RAM) and cosmic compiler.I can see as below.#error clnk Debug\dm5xx_stm8l.lkf:14336 (C:\Program Files (x86)\COSMIC\FSE_Compilers\CXSTM8\lib\libm.sm8)fmul.o: section...
Posted on January 23, 2018 at 21:58Hi,I am using the STEVAL-IHM041V1 demo board to develop my own application. The mcuis STM8S103F3P6. I checked the EEPROM locations to verify that the EEPROM read/writeare fine when the +5V is stable. But I have pro...
Posted on February 01, 2018 at 11:11i use stm8l151g4 pd4 to control external ADC converter,when pd4=1,ADC converter start,and pd4=0,ADC converter stop,pd4 initialized as below: PD_DDR_DDR4 = 1; //PD4- OutputPD_CR1_C14 = 1; //PD4 - Pus...
Posted on January 31, 2018 at 21:55Where do I find (manual and section/table) the voltage required to set external interrupt to low and high and also the minimum and maximum current. I am looking for this information for the STM8L152C6, so somethin...

Posted on April 18, 2016 at 14:20Hi,I'm trying to operate TIM1 on STM8S003F3P6, I am using the standard peripheral library code, but I am only able to produce pwm on TIM1_CH3 (PC3) pin, the other pins do not produce any waveforms at all. I'm sure th...
Posted on January 23, 2018 at 23:47&sharpdefine TIM1_PSCRH (*(volatile uint8_t *)0x5260)I understand that now when I set TIM1_PSCRH = <some 8 bit value> that the Timer 1 Prescaler High Byte register will be set because it is located at address 0x526...

Posted on January 24, 2018 at 12:10Hi, I looking to achieve lowest power consumption in halt mode. Datasheet says we can achieve 350nA in halt mode. I am able to achieve 195 uA(micro Amp) at 1.8V.. I have written simple test code. FYI i am adding ...
