Hi,I'm using stm8s003f3p6 microcontroller and learn it's different internal peripheral. using SPLHow can i write a byte at RAM location like 0x00 and read from it.i also want to use IAP commands for flash.i have read stm8s Reference manual , dastasheet and flash programming manual, but i can't find related to.do anyone has code example ,link or document or sample code.

Good day!I'm using STVD+Cosmic. How do I set up the variable in the RAM at the specific position.I've tried creating new Segment and Section but the variable is declared at another address in the flash.Also, nothing changes when I'm changing min or max addr of the RAM segment in Linker settings. After reset I still see the same data at the area which I subtracted from the segment. Why?I've tried this guide http://www.cosmic-software.com/faq/faq3.phpbut I can't specify the address in the STVD Project Setiings/Linker/Input page.

Hi all.I would to flash a .hex firmware into some STLUX385A devices.These devices are not brand new and de optionbytes allowing serial bootloader has been removed by previous application. Worst-case scenario, the serial pins are not accessible on the PCB. However, pins for the SWIM interfacer are accesible from PCB.Is there any solution to re-flash these devices with some PC software and, for example a ST-LINK programmer?Regards

The below code works with out the initialization "GPIO_Init(GPIOA, GPIO_PIN_3, GPIO_MODE_OUT_PP_HIGH_SLOW);" ,but does not work with initialization.void main(void){ volatile uint8_t count; count = 0x00; GPIO_DeInit(GPIOA); GPIO_Init(GPIOA, GPIO_PIN_3, GPIO_MODE_OUT_PP_HIGH_SLOW); while (1) { count = 0x00 | GPIO_ReadInputPin(GPIOD, GPIO_PIN_5); }}Could some one point to where I might be going wrong?Thanks

Does STM8S001J3 reset protection via STVP? As well as in other series STM8?I did not get through STVP. So far, only through IAR - when connecting, select Option Bytes. IAR warns about clearing all memory, agree and everything is ok.

This is the error message that i have received.#error clnk Release\ild004v2.lkf:62 Release\smart_reset.o: symbol __stext multiply defined (C:\Program Files (x86)\COSMIC\FSE_Compilers\CXSTM8\Lib\crtsi0.sm8)#error clnk Release\ild004v2.lkf:62 Release\smart_reset.o: symbol _exit multiply defined (C:\Program Files (x86)\COSMIC\FSE_Compilers\CXSTM8\Lib\crtsi0.sm8) The command: "clnk -l"C:\Program Files (x86)\COSMIC\FSE_Compilers\CXSTM8\Lib" -o Release\ild004v2.sm8 Release\ild004v2.lkf " has failed, the returned value is: 1exit code=1.There is no problem when i build under debug. However this shows up when i build it under release.The code that I am trying to build is STEVAL-ILD004V2.The photo attached is the error message I got when I pressed start debugging.

I'm a new comer to STM8 uCs, but experienced in other controllers. I have two questions:I would like to bring up a custom test board with In System Program/debug capability using the STM8S003F3. How do I do this quickly? A list of manuals/appnotes would be a start. I do not wish to use any eval/demo board such as Discovery etc. All your suggestions and advice would be appreciated.I am going to use the ST toolset (STVD, STVP, Cosmic and ST-Link V2) . I tried compiling a small test file with the Standard Peripheral Library downloaded from ST.com (en.stsw-stm8069.zip), after making the chip selection in the stm8s.h file, but got an error saying stm8s_conf.h file was not found. The zip file does not contain the file also. Help!Thanks in advanceShiv

On Google there is the formula Time event= prescaler*counts/fmasterFor 2s how should we calculate prescaler.​

There is a st-link. Tried to connect STVP, IAR STM8. Nothing happens. STM8S001J3 is not connected. Power commuted when trying to connect. With constant power, I also tried to connect. Why did you make such a bad microcontroller ?!

I am using IAR EMBEDDED WORKBENCH FOR STM8s. I am running a simple led blink program. But I am facing while deploying to device. It shows the message "FAILED​ TO LOAD DEBUGEE". Please answer about this issue.

Hey guys, i have problem about counters, i have a constanst frequency square wave ring tone signal and this signal have to come to my mcu's input pin and i have to detect it that is ring tone, i think i will gonna do this with counters, i have to open timers for a while and at these times timer try count ticks. BBut i dont know how to configure it and how to add interrupt routines to my codes block. Can u help me ? I found some code below but im not sure about and i dont know how to do.void TIM1_setup(void) { TIM1_DeInit(); TIM1_TimeBaseInit(2000, TIM1_COUNTERMODE_UP, 55535, 1); TIM1_CCxCmd(TIM1_CHANNEL_1, ENABLE); TIM1_ICInit(TIM1_CHANNEL_1, TIM1_ICPOLARITY_RISING, TIM1_ICSELECTION_DIRECTTI, 1, 1); TIM1_ITConfig(TIM1_IT_CC1, ENABLE); TIM1_Cmd(ENABLE); enableInterrupts(); }

Does BlueNRG-1 component works alone as a single chip or does it need to be configured with other MCU for its functionality?

Hi, I am using ST Visual Develop environment for programming of STM8S207, i am using 4.3.6 version. Problem is, whenever i give save command, STVD is halt and shown "Not Responding" My laptop configuration is Pentium Dual Core, 2.0GB RAM, Window 7 Ultimate and 64-Bit Operating System. Please suggest the solution for the same. Same thing is happening in STVD Version 4.3.12Regards,Nandish Jasani.

I am using Cosmic STM8s ide for my STM8S001J3 micro controller. I am not able to add the standard libraries for the microcontroller in cosmic ide. please help me out with this issue.

Good afternoon, I would like to share an issue I’m facing with a stm8s105c4.A feature of our main application is to calculate a CRC of the entire program in the flash. Unfortunately, when I read flash data from addresses close to the instruction in execution, the data read it isn’t always correct.I’ve been able to reproduce the issue in this small program: main() { unsigned char* p_address; unsigned char dataRead; volatile dbg;   /* Loop and read the registers*/ for (p_address = (unsigned char*)0x80ce; ((unsigned int)p_address) < 0x80FF; p_address++) { dataRead = *p_address; dbg++; } dataRead++; }In this case, when p_address points to 0x80dc, this is what we can observe in the dissasembly and the core registers:      1)      This set the address we want to read in X

Hi all,I have a issue about interrupt timer and interrupt button. When i alway press button. Run debug, cursor alway run to interrupt exti line. I change timer 2,4 or pin exti still error occur. When I comment TIM1_Config() i alway press button-->interrupt button is ok. I use STM8S003F3, IDE IAR. Please help me! Thanks. Below code:void EXTI_Config(void){ GPIO_Init(GPIOB, (GPIO_Pin_TypeDef)GPIO_PIN_4, GPIO_MODE_IN_PU_IT); EXTI_SetExtIntSensitivity(EXTI_PORT_GPIOB, EXTI_SENSITIVITY_FALL_ONLY); enableInterrupts();}----------------------------------------------------------------------------------------------void TIM1_Config(void){ CLK_PeripheralClockConfig (CLK_PERIPHERAL_TIMER1 , ENABLE); TIM1_DeInit(); TIM1_TimeBaseInit(7999, TIM1_COUNTERMODE_UP, 1999, 0);//interrupt 1s TIM1_ARRPreloadConfig(ENABLE); TIM1_ITConfig(TIM1_IT_UPDATE, ENABLE); TIM1_ClearITPendingBit(TIM1_IT_UPDATE);

HI ST Team,We are planning to use STM8S103F2 MCU for dimmer application like the STEVAL-ILD004V2 reference board. Do you have IDE we can use (for free) or we need to get Keil/IAR license?Regards,Walter

What is the meaning and root cause of following error:#error cgstm8 xsnprintf.c:195 >123<@generate() PANIC! MOVCNTI am trying to build a custom printf routine. This shows up only after I change the type of some parameters.

Posted on November 17, 2017 at 14:08Hello,i'm searching for the Source Code of the EVAL Board STEVAL-ILD004V2 with STM8S103F2 Controller?I can only found the compiled Firmware.Can anybody help me?Best Regards,Stefan#steval-ild004v2-source-code?

The image below, is of a SNES Classic (Super Nintendo Classic) controller's PCB. I can't seem to find out exactly what MC its using, all it really says is STM8mhz. On LCSC and digikey, they don't even have any 8mhz STM8 MCs, only 16 and 24mhz. This is leading me to believe it may be a custom MC, designed specifically for Nintendo.I would really like to create my own controller for the system. My plan was to download the HEX (I'm new to STM, coming over from the AVR side, so please excuse me if HEX is not the correct terminology), and upload it to another STM8. I just have my doubts it will work if its not the exact same chip.Am I correct in thinking that the HEX file from this MC, would not work in a similar STM8?I was hoping to load it on a STM8S103F3P6, as I have some development boards on the way.Do you think I would be able to load its HEX onto one of those?Thanks

According to the datasheet the RTC_ISR1_RSF bit is by hardware when the shadow regs are updated. Is it safe to assume that the shadow regs will not be updated when the RSF bit is already set?

Hello, I am using a STM8AF discovery board for prototyping and coding development. I would like to use it to establish SPI communication with an external ADC, the ADS1118 from TI. On the datasheet for STM8AF, "The microcontrollers of the STM8AF and STM8AL boards communicate with the L99PM62GXP IC through the SPI interface, that allows control and diagnosis of the device. " I don't see any pinouts for SPI pins available and I only see test points on boards for SPI. I believe the SPI_NSS is connected with the L99PM62GXP already. Does this mean I cannot use SPI on board with a device other than L99PM62GXP? Is there any way to establish SPI communication with ADS1118 in that case?Thank you very much for your help!

I have a board with a STM8S0003F3P6 MCU with its own 5V supply and a few other power supplies. What is the safest way to connect STM8S discovery SWIM programmer?protect 5VThe SWIM pin 1 USB 5V and board 5V could be at different voltage levels. I don't want the USB port to power the board, so I disconnected them. Protect SWIM signals when board is unpoweredThere are 220 and 47 ohm resistors on the STM8S discovery. Is that sufficient to comply with slight power supply mismatch?I am putting a 74HC4066 quad switch to ensure that the SWIM signals don't enter my board when my board is unpowered. The 74HC4066 has two ideal diode circuits to get powered by either supply. Is that good enough?https://www.st.com/en/evaluation-tools/stm8s-discovery.html
