STM8 MCUs

#define RAM_EXECUTION (1) configured with STM8AF52xxUse FLASH_EraseBlock in debug mode to erase normally.In release mode (medium or high optimization) use FLASH_EraseBlock to die.why?

Hello everyone.SLCC generated a strange instruction similar to JRF, represented as .byte 0x21 pseudo-instruction. Can anyone explain what this is? A code snippet is provided in the attachment. The compiler options are as follows: -mstm8 --out-fmt-elf --opt-code-speed --max-allocs-per-node 6900 - -stack-auto -cThanks in advance.

I request sample from estore, but when i get to the shipping page, no matter how i fill out anything, the cointue button cant work and cant pass to next page,so i gave up requesting sample ,so pls st send me free sample stm8s103k3t6, thanks.

Hi All​The customer want to design STM8AF6223A for automotive application, it is have to pass ASIL B certification, but I had confirm ST website(as below hyperlink), the third party website has expired, how to get more detailed information?Thanks.​https://www.st.com/content/st_com/en/products/embedded-software/mcu-mpu-embedded-software/stm8-embedded-software/stm8a-safeasil.html

Hello everyone, I have got a problem but I can't resolve it.I made a project read NMEA string from UART and show it to OLED 128x64 (I2C interface) with STM8s003F3P6. everything is OK when I tried to get GPS strings from UART and store them variable , with OLED also ok and I can show everything on it . But when I combine 2 libs(GPS parsing and OLED disp) I got very strange thing!. After power on, the circuit show all GPS data I need , it run few seconds and auto reset STM chip, all is restart and repeated same way?I can't find where error, maybe stack overflow?the code flow follow:UART_ISR()   { newdata = get_GPS_data(); //get NMEA string , when get all, newdata = 1 }       main() { while(1) { if(newdata) { newdata = 0; pro = GPS_parse(); //parsing GPS data and storge into variable If(pro) //handled afer 2 sec (the UART received NMEA 2s period) { //pro = 0; _disable_interrupt(); OLED_show(); //show data

I am currently trying to put STM8 in sleep mode after 30 minutes if no activity is observed on I2C. I am able to use timer4 to get a delay in ms upto 1 secs but I am unable to get delay in minutes. Do I need to use RTC for this? If so can someone please suggest how I can configure and set RTC clock to get 30 minutes delay. I have gone through RTC periodic wakeup example but not sure if that is something I can use.

HelloI am new to STM8 controllers , I have finished a new project using STM8S003F3 and I am looking for a ISP programmer (flasher ) with standalone capability so the controller can be programmed on a manufacturing line till date I have been using ST-Link V2 for programing and testing the code , ST-link is too delicate for it to be used to program in mass production programming. There are a lot of options on the st web site, But I am confused as to which one is good and reliable . Any one having experience in using this type of flashers and reliability data of any product and pointing me towards which one should I consider would be greatly appreciated.Thanks in Adavance.

Hello everyone,Is it possible to create Run-in-RAM code using SDCC? If possible then how to do this?Thanks in advance.

This bug is several years old and should really be fixed.In stm8s.h, the following line ...#if !defined HSE_Value... should (obviously!) be ...#if !defined HSE_VALUE... in order to allow HSE_VALUE to be defined on the command-line.I just found out that this bug is several years old and has not yet been fixed.See this link:https://community.st.com/s/question/0D50X00009XkZibSAF/stm8l15x-peripheral-library-minor-bug-report(Which interestingly also makes it possible to define the LSE_VALUE on the command-line).

I have an issue when I am using STVD with Cosmic to write a value to EEPROM and read it back.Example code :/* MAIN.C file *  * Copyright (c) 2002-2005 STMicroelectronics */#include "stm8s.h"#include "stm8s_flash.h"@eeprom unsigned char eeValue;unsigned char ucTemp;main(){FLASH_Unlock(FLASH_MEMTYPE_DATA);FLASH_ProgramByte(eeValue, 0xAB);FLASH_Lock(FLASH_MEMTYPE_DATA);ucTemp = FLASH_ReadByte(eeValue);}STVD assembler shows value being written to 0x0000 rather than start of EEPROM at 0x4000.Cosmic have examined files and have determined that compilation was correct and the elf and map files are OK and they believe that STVD is not handling correctly.STVD version is 4.3.12Has anyone got a fix?

Posted on May 22, 2015 at 16:31Hi folks I'm trying to read the (unprotected) contents of the data flash of an STM8L processor via the command line application provided. As this works in the GUI version I assumed I should be able to specify a file to put the output in, but  I can't for the life of me see how. Any clues? Extra info for the interested: I can't use the STVP GUI as I want to automate the process; I could presumably use the provided DLL but that's more complex than I want to get; I don't know beforehand what the contents of data flash will be (verify won't do, therefore). Cheers Jonathan

CLK_PeripheralClockConfig (CLK_Peripheral_I2C,ENABLE);// Delay(2); I2C_DeInit(); /* I2C Peripheral Enable */ I2C_Cmd(ENABLE);  /* Apply I2C configuration after enabling it */  I2C_Init((uint32_t )200000, 0xA0, I2C_DutyCycle_2, I2C_Ack_Enable, I2C_AcknowledgedAddress_7bit); while(I2C_GetFlagStatus(I2C_FLAG_BUSY));it can't continue.

I want to program an external STM8 microcontroller using the ST-LINK/V2-1 portion of the NUCLEO-8L152R8 board. Is that possible? If so, what are the required steps?

I just downloaded the latest StdPeriph_Driver library a few days ago.The line ...TIM2->SR2 = (uint8_t)(~((uint8_t)((uint8_t)TIM2_FLAG >> 8)));... produces a warning. The value written to TIM2->SR2 will always be 0xFF.It's unclear to me what the desired functionality of the above line is.-If this is supposed to use any bits from 'TIM2_FLAG'), the following would be better...​TIM2->SR2 = (uint8_t)(~((uint8_t)((uint8_t)(TIM2_FLAG >> 8))));​... which then again is the exact same thing as ...TIM2->SR2 = ~0;​... but when looking at the code for TIM3, I see the following code ...TIM3->SR2 = (uint8_t)(~((uint8_t)((uint16_t)TIM3_FLAG >> 8)));... which suggests that it might be better to do this ...TIM2->SR2 = (uint8_t)(~((uint8_t)((uint16_t)TIM3_FLAG >> 8)));​... So if the line from TIM3 is correct, then I'd suggest cleaning i

at line 140 , the key io level is 3.2v , it is release status, so it keeps high.but the read pin function can not read the set value out , why?hope you could give me some hand!

pe7 default to GND

I would like to copy a STM8 chip exactly same as the original and the new one should be running . If you show me the way how to do it then I'll be appreciated. What interface can be suitable among the UART, ISP, I2C ? If you provide some sample code then it'll be much more helpful. Thanks.

I am new to stm8s. I have recently installed stvd on windows 7 32 bit. I have written proper code. Their is no compilation error and build is also successfull. But as soon as I click on programmer a window appears that shows stvd has stopped working. Please help me out from this issue

hai every one , i need can j1939 library file, for stm32 or stm8 series. please share ,thanks in advance .

Please do share any link or code? I am really stuck in my code

Hello.I have a question for you:Is it possible for your STWBC-EP device (STEVAL-ISB44V1) to transfer user data (UART-port) to the STWLC33 microcontroller and vice versa? :User Data - "STWBC-EP" - "STWLC33" - User & User Data - "STWLC33" - "STWBC-EP" - User?
