Discuss STM8 microcontrollers, including SWIM, USART configurations, RTC usage, ADC issues, and debugging.
Issue with STM8S103 Code Uploading on Identical PCB BoardsI have two identical PCB boards, both equipped with the STM8S103 microcontroller. One board functions perfectly, with code uploading and running as expected, while the other does not.Observati...
Hello,given that the longevity commitment of the STM8 chips has been renewed for another 10 years, is an update planned for the old STVD development environment, which is no longer in line with other similar IDEs and also has some bugs? Sebastiano
I am studying a project that requires a very small microcontroller. It will only drive analog and digital ports, but we need the I2C protocol and maybe even CAN. I was advised to use the STM8, but I am not comfortable with this choice. And I wanted ...
Hello guys,I found the datasheet on ST web was released in 2011.https://www.st.com/resource/en/user_manual/um0817-stm8sdiscovery-stmicroelectronics.pdfIn this old document, it state the hardware requirements as below:- USB cable type A to B- Computer...
I've been struggling to demonstrate timer capabilities, with some success but a lot of unexpected failures. I don't see any "application notes" (ANxxx) in the documentation and very little howtos in the reference manual. Is there a list of recipes fo...
Hi everybody,I am using the STM8S003F3P6 development board (little blue one bought from AliExpress) and I am trying to program it using ST-LINK V2 (also bought on AliExpress). I wrote the code using STVD and now I would like to program the MCU. I tri...
Hello,I need to debug and program an STM8S MCU. However, when I try to debug using IAR, I encounter the following error:"Failed to set configuration with MCU name STM8S208C6: SWIM error [30006]: Comm init error: chip does not answer."When I try to pr...
Hi,I guess there is a bug in manual clock switching (file: stm8s_clk.c function:CLK_ClockSwitchConfig:( /* Wait until the target clock source is ready */ while((((CLK->SWCR & CLK_SWCR_SWIF) != 0 ) && (DownCounter != 0))) { DownCounter--; }Mus...
Building Discovery Debug and Release errorsSTM8L152C6 MPUHow to set full path when building to show details?I read somewhere that there is a selection for building a lengthy display. Where is this explained, please? Where is the COSMIC C compiler lis...
Hi, We are trying to solve some problems regarding our SPI bus (bus stability, due to multiple branches in noisy environments) and reduce costs by eliminating a SPI sensor and make our STM8 to read a NTC. We would like the system to answer as the old...
