STM8 MCUs

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...

Windows openocd stm8s debugging?

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...

How to program STM8 MCU with ST-LINK/V2-ISOL using an USB-over-Ethernet adapter (Eltima driver)

Hi everyone,we are using a device called "Helmholz REX 100 WAN" which supports USB-over-IP over its VPN-tunnel. It needs an Eltima windows driver on the client computer.I'm trying to get the ST-LINK/V2-ISOL working so that I can programm an STM8 remo...

How do we program STM8AF EVK board?

Hi team,we are plan to use STM8AF board. Whether it is support internal programmer or else we need to purchase separate programmer. please confirm it Thanks Manjunatha
