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 ?
Hello, I am using the Stm8s003f3p6 processor. I want to create 1 microsecond time on processor. I tried TIM1 and TIM4 peripherals for this. I gave the values of 2, 4 and 8 respectively as Presecaler values. Again, I gave 7, 3 and 1 values as periods,...
The right side of the source code displayed in ST Visual Develop is displayed in red.Does anyone know how to solve this?Also, is there any problem if it is displayed in red?I would appreciate it if anyone could tell me.
