STM8 MCUs

In order to make some gang programmer for the STM8 parts we want to use a STM32 processor. Is there public code available which does implements the SWIM interface on the STM32 parts ?

In order to create a gang programmer we were thinking of using multipe STM32 processors were every processor implements the SWIM interface in order to program STM8 processors in parallel. We can we find code written for a STM32 device which implement...

STM8S001J3M3 pull-up resistor value on PB4

In an application we use PB4 as output. Corresponding to the datasheet, this port only can be used with open-drain. In the datasheet in the I/O port pin characteristics there are values of 30k up to 80k for pull-up resistor Rpu. Is this meant for the...

I have a problem with: " USART_Init(..)" in STM8L051F3. If I use this procedure I noticed with the debug that the registers are not set. Can anyone help me to use the usart (asyncronous mode) in STM8L051F3.

code development manual for STM8L

Hello,I am using NUCLEO-8L152R8 board for our project purpose.I am new to this board. I have downloaded tools like STM8Cubemx, ST visual develop.I haven't found any video or document which will guide me on how to develop code in ST visual develop and...

STM8 'Read While Write' function necessary to ensure serial RX while accessing EEPROM?

Hi,I am looking at STM8 MCUs and am trying to figure out, if I need the RWW functionality. I want to save data to EEPROM after a specified time has elapsed and read at random times from the data EEPROM. I also want to have UART comms running.To ensur...

8-pin part label part identification (ST G9949)

I'm trying to identify an 8-pin part that appears to have an "ST" logo on it. I'm pretty sure it is an 8-bit MCU, (part of a LED tube driver dimmer control) The part numbers looks like ST G9949, but I can't find a match on ST.com. Does ST custom labe...

Hey, The STVD latest version available from the Website is 4.3.12. But its user manual On the Website (Doc: UM0036) is for STVD version 4.0.1 (Which is released in 2010).I can't find any User Manual DOC for STVD latest Version 4.3.12.anybody any Idea...

I have sttoolset pack42 STM8 IDE source but it can't installed into my laptop so please help me for that issue

Hi, I´m using STM8S0003F. I have 2 pins at PORT A (PA1 and PA3 that are programmed to generate an interrupt when any signal FALL_ONLY. During the interrupt routine, how can I know which pin generate this interrupt? Thank you Andre
