Discuss STM8 microcontrollers, including SWIM, USART configurations, RTC usage, ADC issues, and debugging.
Posted on November 07, 2013 at 12:40We use the STM8S003 MCU in one of our products and specifically we use the LINbus communications in slave mode. In the 003 datasheet it says the UART (UART type 1) can actually only support LINbus master mode. Whe...

Posted on November 03, 2013 at 00:51Hello. I've a 24C32 on the good pin of my stm8s, I use the stm8 eval library but i've a sEE_TIMEOUT_UserCallback all the time. Is there a better library ? Thank you
Posted on June 10, 2013 at 16:48Hello everybody,I'm programming a STM8L152C6 on the STM8L-discovery. Wanting to improve the consomption I tri to power down the HSI. For that I use the instruction // Clock source CLK_LSICmd(ENABLE); CLK_SYSCLKSo...
Posted on July 28, 2013 at 18:44DEAR ALL, I WANT TO USE STM8S TIM3 CH1 AS SPEED MEASUREMENT OF MOTOR VIA PULSE INPUT. I HAVE 12 PULSE PER ROTATION. HOW TO START OR ANY IDEA FOR GETTING STARTED WITH THIS. #st
Posted on June 13, 2013 at 13:27I want to use stm8L watch dog in halt/halt-active mode. my system wakes up by RTC.1. when I choice Independent watchdog, a watchdog reset happens when system is in halt/halt-active mode. As you know, the option byte(0...
Posted on October 09, 2013 at 23:02I'm using Cosmic 4.3.6 compiler & have a project with greater then 32k code. I need to checksum the flash at startup and periodically during runtime to satisfy UL60730. My first project (about 12k code size) went...
Posted on October 25, 2013 at 00:18I have an STM8L application that needs to scan several ADC channels on a fixed time basis, so I used the ADC_DMA code from the STM8L standard peripheral examples as a starting point. The timer is set to a 1KHz trig...
Posted on October 10, 2013 at 08:52Hello, I have a simple question: uint32_t temp; temp |= ((uint32_t)1 << 16); without retyping it does not work (although if I add the expression to Watch, it shows expected 1 on 16th bit of temp). Why? I use Cosmi...
Posted on October 18, 2013 at 16:42I'm using the Cosmic 32k compiler version 4.3.6 and STVD Version 4.3.1 for a project with an ST8S208C chip. The problem seems to be the compiler. Whenever I do 32 bit math while interrupts are on, I occasionally se...
