STM8 MCUs

I am using an IAR compilation environment, the microcontroller is STM8S105C4T6, but in the clock initialization, CLK__CKDIVR=0x00; the CLK__CKDIVR in this sentence keeps prompting that this function cannot be found.And it is the same when initializing the serial port UART1. The header files used are stm8s.h and stm8s_uart1.hMay I ask what is the reason for this?

I have just come back to STVD after a long while (and various changes of machine) and have reinstalled STVD and COSMIC. I can now compile my existing code but when trying to link it during the build process I get a page of errors like;#error clnk Release\bhcpu_rev05.lkf:1 symbol f_CLK_SYSCLKDivConfig not defined (Release\main.o )I have no doubt that there's some setting in the linker that I have failed to configure but can find no clues online.This code compiled and linked without error on the old system so it's likely soemthing I have done, or not done.Does anyone know what's going on here?Thanks :)

I'm currently using the STM8L151F3 and implementing the SUMP open logic analyzer. In one part of my code involving with GPIO reading and send data to SPI1_DR. and to make a lots of the capture samples, I use the F-RAM as a external RAM for sampling memory. Since the F-RAM is really fast and practically almost no delay (SPI running at 8MHz). My question is can I use "mov" instruction to "copy" data from one peripheral address to another ? this part taken from my code at line 231. https://github.com/TiNredmc/stm8l_sdcc_template/blob/master/code/ComeNCapture/main.c#L231// Notice : SDCC compiler do{ __asm___("mov 0x5204, 0x5006");// PB_IDR -> SPI1_DR while(capture){

Im using the COSMIC Toolchain with the standard library.Here is the setting:##########################################################void clock_init(void){ CLK_DeInit();              CLK_HSECmd(DISABLE); CLK_LSICmd(DISABLE); CLK_HSICmd(ENABLE); while(CLK_GetFlagStatus(CLK_FLAG_HSIRDY) == FALSE);                  CLK_ClockSwitchCmd(ENABLE); CLK_HSIPrescalerConfig(CLK_PRESCALER_HSIDIV1); CLK_SYSCLKConfig(CLK_PRESCALER_CPUDIV1);                  CLK_ClockSwitchConfig(CLK_SWITCHMODE_AUTO, CLK_SOURCE_HSI,  DISABLE, CLK_CURRENTCLOCKSTATE_ENABLE);     &nbs

Hello, I have a strange problem with STVD. The changes to the project are not saved. After closing and openning the project, non of the changes are saved. I appreciate any help. Best regards

We use STM8 micro for one of our projects and the ST Visual Developer for the development environment. We are in need of debugging some of our units for warranty return analysis and ST visual developer is giving weird errors stating not able to detect the debugger. But the ST visual programmer was able to detect the debugger and displays the serial number. The errors are:• ** Connection error (usb://usb): gdi-error [40201]: can't access configuration database.• ** GDI error: The debug is not possible with the Hardware watchdog selected.Both the above errors are being observed.

Yes I want to flash my hex file to the board (connected by usb) from my VS Code setup.I've looked in vain for a windows version of STM8flash. Anyone have a link to a ready built executable?I understand that this should also be possible using openocd, but when I tried I got errors about the SWIM not being available. I thought openocd was for debugging - that's for later!I can flash via STVP, so I'm not stuck, just want it a bit more automated.Thanks :)Gordon

I would like to read STM8S001J3 data memory and store it to HEX file.I dont0 know how to specify file name for the output file. If I use -FileData STVP searches for the file and produces an error.Thanx.Command line : STVP_CmdLine" -Device=STM8S003F3 -verbose -readData -no_verifOutputSTVP_CmdLine version 1.6Verbose ONLog activity ONDisplay Progress OFFMessage box warning if protect option byte ONLoop mode ONErase device OFFBlank check device OFFVerify device OFFConfiguration:BoardName=ST-LINK ST-LINK_ID=0 Device=STM8S001J3 Port=USB ProgMode=SWIMHit 'Esc' key to abort during communication.>>> Reading DATA MEMORYCut Version and Revision of device: 1.2<<< Reading DATA MEMORY succeedsHit 'Space' key to stop or any other key to loop

I'm looking for a programmer who can choose the "SWIM" format to write to the STNRG388A evaluation board (STEVAL-ISA164V1)."ST Visual Programmer" can select "SWIM", but it seems that the device does not have STNRG388A and cannot connect properly.I would appreciate any advice.

I usually use STM8L151C8T6 micro-controller.But it's difficult to get it.What does ST Micro think the major/main products on STM8 CPUs families?Should I change the micro-controller from STM8L151C8T6?So, what kind of families should I use?Please tell me that.Thank you.

Hello, According to table21 in the datasheet, the current consumption (IDD) depends on whether the code is executed from RAM or Flash.How do I determine if my application code is running from RAM or Flash?Regards, Gotoda​

I have a STM8AF6223A Processor connected to another processor on Pin 2, UART TX and Pin 3, UART RX. The oscilloscope verifies that both processors send correctly, 19200 Baud, 8bit Data, no parity, 1 stop bit. The STM8 processor receives the data in the UART4->DR register mostly correct, but not always correct. How is it possible that the RXNE Flag does not get set?I am using the stdlib STM8S/A Standard Peripherals Library V2.3.1 26-April-2018. The IDE is ST Visual Develop with the Cosmic Compiler.This is my example code: The waitCounter always increases to 1000, the RXNE Flag is never set. At the same time the other processor sends 0x55 constantly, the data is available.

The following is the main.cIt's a simple demo for RTC display on LCD. The second run correctly, which means the system and RTC clock set correctly. However, the minute does not change when the second runs a circle (60s). Do I set the registers incorrectly and forget set sth? void main(void){ u8 H_shi=0,H_ge=0,M_shi=0,M_ge=0,S_shi=0,S_ge=0;     system_init();   GPIO_Init(); LCD_Config(); RTC_Config();     LCD_GLASS_Clear(); LCD_GLASS_Confirm(); Delay(50); LCD_GLASS_Clear(); LCD_GLASS_Confirm(); Delay(50); LCD_GLASS_Clear(); LCD_DisplayNum(4,1); LCD_DisplayNum(3,5); LCD_DisplayNum(2,6); LCD_DisplayNum(1,8); Delay(50); LED2 = 0; LED3 = 1

Hi there!I am using stm8s MCU for my application. As the number of data that I want to save is more than the size of EEPROM, is it possible to read/write data on flash memory? If yes, may I know how to make it works and how to allocate flash memory page/stack so that there will not be any crash between data memory and program memory.Cheers,Morris

I test push and pop instruction，some issue confuse me. ​push cc #cc = 0​​when cc=0，and cc is push to stack，the value in stack is 0x28，this mean I1 I0 is set，why？​​pop cc​ #cc=0​when​ cc in stack is 0x2b，after pop，cc change to be 0x3 ，this mean I1 I0 is cleared auto，why？​the behave is correct？Please help me.thanks.​

Hello friends!I have self-developed a programmer for STM8.It works very well.However now I want it to be able to debug in IAR like STLink.Please give me documentation or instructions on how to do it.

Hi. I made a code that uses ADC1 in single conversion mode and UART in asynchronous mode.But when I do the ADC1_Init() for some reason the RX interrupt of the UART doesn't work, if I don't use the ADC1 it works normally.

The command is here but isn't functionally and also I can't configure a specific directory for the log.

I would like to something like this in the build configuration:#define DEFTEXT "some_string"This is the relevant section of the cxstm8 manual:-d*> define symbol...-d*^specify * as the name of a user-defined preprocessor symbol (#define). The form of the definition is-dsymbol[=value]; the symbol is set to 1 if value is omitted.You can specify up to 60 such definitions.I tried all kinds of variations but I could not get it to work. Anyone knows how it is done?Cosmic proposed:-dDEFTEXT=\\\�?singleword\\\�?-d�?\�?DEFTEXT=\\\�?a short string\\\�?\�?�?When I enter this in the additional options box it gets changed to the following:"-dDEFTEXT=\\\singleword\\\""-d\DEFTEXT=\\\a short string\\\\"Best regards,Christian.
