STVP with STM8S103F3 and St-Link/V2: "Error : Cannot communicate with the device !"

Hello,I am trying to program a STM8S103F3 on one of these chinese breakout boards with an original ST-LINK/V2 programmer. Everytime I try to read/ write something I get: "Error : Cannot communicate with the device !Check the SWIM cable connection and...

Hi, am working in stm8l152. I have a problem with my STM8L device. My current remains in 2.02mA even in the halt mode (I would like to obtain 10-15µA). What are the ways to drop this value?

I also tried to make some configuration changes in the code, like putting the halt mode or disabling the timers.Kindly suggest me to solve this issue

RS232 communication with a terminal using STM8L-DISCOVERY.

Hi,Reference: AN5179 - RS232 communications with a terminal using the STM8 Nucleo-64 boardshttps://www.st.com/resource/en/application_note/dm00513075-rs232-communications-with-a-terminal-using-the-stm8-nucleo64-boards-stmicroelectronics.pdfAN5179 pag...

I use STM8L152 in my product. VLCD is connected to external pull-up 3.3V. If uart communication occur, VLCD is pulled down to low level. I short connect VLCD and PD1 and set VSEL to 1 then use PD1 to detect the falling edge. Is there any potential risk?

Since I short connect VLCD and PD1, when there is uart communication, there will be communication waveform like below on VLCD pin, will this affect MCU work?  I set VSEL to 1(External source) by the code below in MCU initialization CLK_Peripheral...

STM8AF5288: Program stops in Block write to flash

Hello,I try to write into program flash in block write. Therefore I have a functionwhich is executed from RAM:void ram_flash_write_block(uint32_t startaddress, const uint8_t *buf) { uint16_t i = 0; // enable flash block write FLASH->CR2 = FLASH...

I failed to compile the source file under ST Visual Develop. How can I solve the problem?thank you

Read Access to flash beyond address 0x10000

Hello,I try to read from user flash. Everything is fine until I try to read from address beyond 0x10000. Then I get random values. I use SDCC (3.8.0 and 4.1.0, the behaviour is the same). My device is STM8AF5288 which has 64 KB of flash memory. A pro...

STM8 ADC does not use the whole conversion result buffer, despite the manual saying it does

I want to use the single buffering mode of the ADC on a STM8S003.As the reference manual describes, in this mode then 8 or 10 consecutive conversions (depending on the model) are carried out on a single channel. The results are stored in ADC buffer r...
