STM8 MCUs

Posted on April 06, 2017 at 16:20Hi. I change memory model and libraries for code larger than 64K. The error receive after linking: #error clnk Debug\canli.lkf:1 symbol __stext not defined (Debug\stm8l_stl_startup.o ) The command: 'clnk -l'C:\Program Files (x86)\COSMIC\FSE_Compilers\CXSTM8\Lib' -o Debug\canli.sm8 -mDebug\canli.map Debug\canli.lkf ' has failed, the returned value is: 1The code is #define GotoCompilerStartUp() _asm('xdef __stext\n jp __stext\n'); /* _stext() */When i change memory model and libraries for code larger than 64K,  Should i update assambly code in different way?Best regards. irfan

Posted on November 18, 2015 at 07:54Hello,      We had developed one application using STVD IDE & cosmic compiler with 8k limit, for that we have following error while compile the code.#error clnk Release\stm8s003.lkf:1 segment .text size overflow (1358) The command: ''clnk -l''C:\Program Files\COSMIC\32K_Compilers\CXSTM8\Lib''  -o Release\stm8s003.sm8 Release\stm8s003.lkf '' has failed, the returned value is: 1exit code=1.    Now we have cosmic compiler with STM8_STM32_32k license.lic file which is copied into License folder & then compile the code but still we have same error as above so please help us & give solution.Thank You.

Posted on August 29, 2014 at 20:15Hi, I can manage to change clock from HSI>HSE and vice versa. But I am not able to bring LSI as my master clock. Can anyone help please?I am using STM8S Discovery board and Cosmic C as my compiler.My code is as follows:/* MAIN.C file *  * Copyright (c) 2002-2005 STMicroelectronics */&sharpinclude ''stm8s.h''u16 c=50000;u8 i;main(){ ErrorStatus status; CLK_DeInit(); CLK_HSICmd(ENABLE); while (CLK_GetFlagStatus(CLK_FLAG_HSIRDY)==0); CLK_LSICmd(ENABLE); while (CLK_GetFlagStatus(CLK_FLAG_LSIRDY)==0); CLK_SYSCLKConfig(CLK_PRESCALER_CPUDIV1); CLK_HSIPrescalerConfig(CLK_PRESCALER_HSIDIV8); CLK_ClockSwitchCmd(ENABLE); CLK_CCOConfig(CLK_OUTPUT_MASTER); CLK_CCOCmd(ENABLE); GPIO_DeInit (

Posted on October 23, 2014 at 23:03I wrote a http://www.colecovision.eu/stm8/L-Discovery%20LED.shtml that shows how to blink LEDs on a STM8L-Discovery using free tools only. It consists of a few lines of C code to set up a timer, implement clock(), and use it to blink the green LED exactly once per second and the blue LED exactly once every two seconds. The C code is compiled using sdcc 3.4.0 or newer and put onto the board using the free stm8flash utility. Please tell me if  you find anything wrong or missing in the tutorial. Philipp

Posted on March 15, 2017 at 11:45Hello,I have a problem with the ISB027V1 Eval.Board. I have flashed and erased the Firmware and now I am looking for the File that is mentioned in the user guide WBC_FW_A11 .... but I cannot find it anywhere. Can someone please send it to me or advise me where I can find it.Best Regards, Feliks Hoxhallari#gui #uart #wireless #stm8 #isb027 #qi

Posted on March 06, 2017 at 23:07Hello! I can't initialize internal CAN bootloader on stm8AF52A8 with HSE 24 MHz, it is silent.I tested all: �bootloader enable� option byte is set.CAN is OK, i tested it in my program.HSE is OK.Soft on PC is OK, I tested it with kit MB1036, as a flash loader. MB1036 have  stm8af5288 with 16MHz.Any ideas? Maybe there are subtleties that I'm missing?#stm8-can-bootloader

Posted on March 10, 2017 at 13:28Hello guys, I am having some problem while using independent watchdog in stm8s003f3 uc . Actually my all routines run in timer interrupt , ADC interrupt or external interrupt. Independent watchdog works properly in ADC  interrupt  or timer interrupt. Watchdog reload in adc, timer2 or external interrupt. But when external interrupt occurs, the watchdog reset the controller. Please solve my problem as soon as possible.#stm8s003f3

Posted on March 09, 2017 at 07:55Plese let me know If ST has any RF remote communication IC , for interfacing with MCU. I want to replace IR remote with RF remote. Thanks

Posted on October 26, 2016 at 11:18Hi, I'm using the STM8L052R8 for temperature measurement, so using an ADC channel, and then displaying the temperature on the LCD.It would be really handy to be able to clear the LCD Ram memory instead of writing to every LCD Ram Register used. Is there a generic command that will do this for me, I can't see it anywhere.Thanks in advance.

Posted on January 19, 2017 at 10:22Hi,Was looking at a recent version of a datasheet for STM8S003F3P6, and there seems to be no comments relating to a bandgap on AIN7.There was mention of it on previous datasheets (I have one from 2014).Is the bandgap officially present on this uC? My code is showing that it physcally is there - as I am getting readings relative to Vdd voltages.Thanks,Martin.

Posted on February 26, 2017 at 10:17HiI`m new with the STM8S-Discovery and the STM8S105.I usually write my code in assembler so I get a deeper touch on the micros hardware.But I encountered an issue with the STVD tool.When I`m entering the debug mode and push the RUN button I can seethe red LED next to the USB connector blinking. But the simple code does not work.The code should make the green LED blinking, but it doesn`t.I can`t see any error message or other info.But when I set the cursor on the first command(bset) of the code with SET PC(Debug menu)and then select CONTINUE(Debug menu) the programm works. The green LED flashes correctlyuntil I stop the programm.I can read out the code with STVP, so the micro is flashed.But the programm does not work after unplug and replug the USB connector.What I use:ST Visual Develop 4.3.10Windows 10

Posted on February 15, 2017 at 15:31In the UM0560 bootloader flowchart the flash address at the end points to 0x6000 which is the same as the ROM address.Is this intended?

Posted on March 01, 2017 at 12:09Hello,  I am trying to  make a 200us pulse,using simple time dealy.  I am using TIMER4 to create delay. But the problem is whatever prescalar I  use or  What ever Autoreload value I have timer always gives 12us pulse.  I am using stm8s003f3p6 controller.Code is below:#include 'STM8S003F3P.h'void InitialiseSystemClock(void);void InitialiseSystemClock(void) { CLK_ICKR = 0; // Reset the Internal Clock Register. CLK_ICKR = (1<<0);; // Enable the HSI. CLK_ECKR = 0; // Disable the external clock. while (!(CLK_ICKR & (1<<1))); // Wait for the HSI to be ready for use. CLK_CKDIVR = 0; // Ensure the clocks are running at full speed. CLK_PCKENR1 = 0xff; // Enable all peripheral clocks. CLK_PCKENR2 = 0xff; // Ditto. CLK_CCOR = 0; // Turn off CCO. CLK_HSITRIMR = 0; // Turn off any H

Posted on March 01, 2017 at 07:56Hello, I   am trying to  create  100us seconds pulse which periodically triggers  a triac. Timer 1 is used for periodic delay and a while loop is under the  timer1 isr for 100us pulse. Problem is it is not working,Interrupt occurs but pin state doesn't change.  Here is the code: #include 'STM8S003F3P.h'void InitialiseSystemClock(void);unsigned int i=500;void main(void){                   InitialiseSystemClock();  // Internal  RC clock initialization ,frequency 16MHZ                                          &

Posted on March 01, 2017 at 07:47Hello,   I   am trying  to make  narrow pulse  using timer1 of stm8s003f3p6, without using any kind of pwm(because my application  doesn't permit me to do that). Program is,timer will make PIN 18 of mcu high the a  while loop will start under   the timer interrupt service  routine. (While loop is for creating some micro-seconds delay ,say 100us, untill then the the pin is  high then after 100us pin will be low). Problem is that timer interrupt works fine but PIN  is totally idle, nothing happens. Timer interrupt occurs but there is no change in pin state.  Please tell me if some one has any suggestion. The  code is below: #include 'STM8S003F3P.h'void InitialiseSystemClock(void);unsigned int i=500;void main(void){    &nb
