Discuss STM8 microcontrollers, including SWIM, USART configurations, RTC usage, ADC issues, and debugging.
It has been weakly suggested in other threads, but I would appreciate a firm confirmation. Does anybody have first-hand experience doing this?Is anything else required? For example connecting the grounds of the SWIM and JTAG? (Hard to guess the corre...
HiI plan to program my MCU using a Tagconnect cable. I haven't bought the Tagconnect cable yet, nor the st-link v2, and I would like some recommendations.Is anybody using this setup? What are your thoughts?It also seems there are different versions o...
On STM8 controller the 4-pin SWIM interface has a power pin (pin#1) that has been indicated to sense the target voltage. Can this pin be repurposed some way to drive the target board ? So SWIM interface provides output power so the target circuitry d...
Hi there,I have made changes to the firmware and , via ST-Link V2, I would like to reprogram an STM8L050J3, which I had previously programmed with the Active Halt function enabled, but SVP does not allow it and responds with this message as the attac...
I am trying to get a pulse out of TIM2 in compare mode but I see no output. Here is my snippet of code:#include "iostm8l101f3.h" void main( void ) { CLK_CKDIVR = 0x01; // 8MHz PA_CR1 = 0xFF; // all pullups PB_DDR = 0x01; // 0000 0001...
Hello,I am developing a project with STM8L050J3 microcontroller using Evaluation Board STM8-S08-DISCO and STVD version 4.3.12.I need to calibrate the internal HSI oscillator, but for some reason that I have not been able to identify, although I compi...
I have this little project for the STM8L101F3 that just writes an arbitrary value to TIM2_CCR1H and TIM2_CCR1L and then tries to start the timer but I get nothing from the timer output.If I run the project with a debugger and inspect the contents of ...

Hello, there is posibility we mixed STM8L101F3 vs F3U. There is marking L1S3 on the top, but I can't find any information/table of these markings. Is is possible to have it ?
