Discuss STM8 microcontrollers, including SWIM, USART configurations, RTC usage, ADC issues, and debugging.
Hi,Using ST Workbench debugger my 16-bit timer TIM2 (china bought) overflows each 16 seconds as the prescaler is set to 10. With an 16MHz internal clock divided by 2^10 (1024) the timer should overflow theoretically each 4.1 seconds. Prescaler 9 take...
We are working with an STM8L with ST Visual Development Tools and Cosmic STM8 on Windows 11 and the ST-LINK/V2 and SWIM Connector. We can compile, build, and program but NOT debug. We get the attached Debug Error:We have tried the recommendations fr...
Hi,I fell in love with this cute little uC and created all kinds of succesfull projects.Now I have a problem. I want to decode DCF77 time signals. I bought me a few DCF77 receivers from China. They all work fine. I connected the data output of the DC...
Hello,I’ve been working on implementing a SWIM master using an STM8 device to interface with a STM8S105K6 target. This is part of a tester software project that was previously using the ST7 debug protocol and is now being ported to the STM8.I’ve foll...
Hello!Is it possible to save data to EEPROM in STM8S001J3 after VDD drops (power outage)?I would appreciate any case indication. I appreciate any help in advance.
I am trying to make a project using STM8S105K4T6 and NEC based IR remote. I am using Sduino to program the board. I want to turn on and off two relays and two leds using IR remote. Please help me to make the IR decoder for the board.
Hi, please, I'm looking how to program STMS8001J3 in order to generate a reset using bandgap (AIN7) reference voltage. Thanks.
Dear Members of the ST Community,I hope this message finds you well.I am writing to seek assistance with an issue I encountered using the STVD-STM8 software. The details of my setup are as follows: Software: STVD-STM8 version 42.0.0Target MCU: STM8S1...
Hi, I use a PCB that is reduced to one STM8AF5288 and 3 100nF Capacitors. No other components, all are removed. I supply it with 3,3V. I want to reduce current consumption in halt-mode to 4,5uA. Some others posted simliar problems, I could never find...
Could you please assist me with the sample code for SMBUS communication using interrupt mode in STM8S with a battery IC BQ76930(I am trying to read the temperature and voltage and Device ID)?
