STM8 MCUs

Hello I am new to the world of micro controllers and stm8 in general and I wanted to know how to enable halt mode (A sample code would be nice)

Hello , I am able to generate the different frequency tones using the beep function. Can anyone guide how to play musical tones let's say happy birthday song on piezo buzzer?

Hello,is there any documentation or tutorial on how to get the demo in the STM8-LIN-Package running. The Documents AN3055, RN0086, UM1593 don't really explain this.Thank you for your help

So i get very frustating about ST a such big company. Why they not stable good IDE and example as like Microchip.I google lot but not to get write answer Kindly help me to learn ST MCU's in easy way as like my experience to learn Microchip.Thanks and RegardsMunna kumar

1. I am using STM8S003F3 & exploring options for IDE available. It has 16Kb flash, which ide is free for 16KB?2. There are options here: https://www.st.com/en/microcontrollers-microprocessors/stm8s-series.html#tools-software3. I am using IAR 3.11 which is limited to 8KB now for free version. Didnt it used to be free for upto 16KB for previous versions?I checked IAR website didnt find where to download old version and see which was free till 16KB flash?

This should cover:How to initialize timers and prescalers, How to write and read data.I am using :STM8L050STM8-SO8-DISCO for evaluation.Standard Peripheral Library (stm8016StdPeriph_Lib)Thank you.Volker Peters.

Currently, I am working on STM8S103F3. I wanted to build custom bootloader for it as it doesn't have inbuilt bootloader. So I followed the procedure given in "AN2659" document which describes how to use example bootloader given by STmicroelectronics. Example program for boot loader is given for STM8s105xx so I changed parameters in /* USER BOOT CODE MEMORY PARAMETERS */ according to the STM8s103 in main.h file. In STM8s.h file I uncommented  the controller I am using

Hi ST Team,Hope you guys are doing well !!!.Can you explain me in detail regarding the usage of Window watchdog generates a reset when MCU enters Halt mode  and Independent watchdog continues running in Halt/Active-halt mode. If you have any document related to that, please me .Thanks in Advance!!!Regards,Anand Kumar

Hi,I'm attempting to connect to STM8L052C6 with ST-link and receiving an error, "Cannot communicate with the device !"I've read every forum post on google related to the issue and tried just about everything to connect.Finally I found in the manual for SWIM entry sequence in reference to activation timing to make SWIM active the pin must be forced low during 16µs, next a sequence of four pulses at 1kHz (1ms), followed by four pulses at 2 kHz (500µs)When I checked the pulses I found the initial low is 1.317ms, followed by four pulses of 1.334 ms, then four pulses of 0.667 msCould this timing be the issue why SWIM is not initiating?

Hey, I am adding this post to mention about the tutorial series that I am currently working for beginners to learn STM8 Microcontrollers. The tutorial s are targeted for absolute beginners, so you find everything from circuit diagram to code explanation in the links listed below Getting started with STM8S Microcontroller Blinking LED on

hiComsic STM8 compiler suite version: 4.4.12.I am using this compiler version together with ST's STVD.In the sample code attached, with line 13 conditional define set to 0, the compiler yields compilation error (my intended implementation), and the alternate fix is demonstrated with conditional define set to non-zero (my temporary fix).Can any users or cosmic support check if this is actual the same as what I experienced to ensure this is actually a compiler issue, or any option setting issue.RgdsCalvin

In DT0094, KeeLoq RX application over S2-LP, the following is mentioned:KeeLoq firmware example for RX node available on request through local marketing / sales representative.Has anybody got a copy of this?

I have an STLINK-V3SET with MB140B adapter.I am trying to program an STM8S003F3P (minimum evaluation board) over SWIMI've installed the en.stsw-link009 driver on my Windows10I've put jumpers on JP4 and JP6My code is specific for STM8S and compiled and builds fine.When I use STVD or STVP to program the code on the chip, when pressing start I get the following:Cannot communicate with the device, check the SWIM connection...I tested continuity, everything is fine.I actually think the STLINK-V3SET isn't working right!When doing ST-LINK Upgrade, on Device Connect, I get: The content of the ST-Link is corruptI don't know if the ST-LINK Upgrade is just not compatible with the V3SET or my LINK is really broken...How to start debugging my problem?Thanks

Hello,The STM8S003F3 is a Value Line device with quite small number of write/erase cycles. The data sheet says:Program memory: 8 Kbyte Flash memory; data retention 20 years at 55 °C after 100 cycles---My wife is going to use very cheap W1209 thermostat module for lab classes in her school. This module based on STM8S003F3 has 7-segment display, buttons, led, relay, temperature sensor.----What makes me thinking is the small number of write/erase cycles. Assuming that the required minimum data retension is a few weeks (maximum period between classes) - how many write/erase cycle is expected for the STM8S003F3 in the room temperature? Thanks,Bogdan

AN2957 is specifically for RC5 IR transmitter. I need implementation support for Reciver/Detector using STM8 series of MCUs.There is AN3174 which has the basics of RC5 but the implementation is focussed on STM32 series.

The chip I use is STM8S003F3. When using Flash block erase, it is executed in RAM. If the offset of the Flash address is used with a 32-bit variable, the execution will cause an error. Can this 8-bit microcontroller use 32-bit addressing in RAM?

Hello!uid address for STM8L051?

Hi,I am the author of an OS tool flash tool named "stm8gal" for programming the STM8 via the ROM bootloader. Currently I check family type and memory size by probing different addresses. This is extremely ugly and may fail in devices I couldn't test yet.Much better would be to read the variant ID (not UID) and memory size, which I assume are stored in flash somewhere...!? Unfortunately I was unable to find any documentation about this. Can anyone provide more information about this? For your help thanks a lot in advance!

I want to use count external pulses count coming on Timer 1 channel 1 .I wrote following code. the couter starts counting as I apply external pulses.but the counter doesnot go upto 65535 value. it gets reset intermittently.I want to use counter to count incoming pulses continuously and also want to use its overflow interrupt. My code is as below. Please advice me how can I resolve the issue. GPIO_Init(GPIOC, GPIO_PIN_1,GPIO_MODE_IN_FL_NO_IT ); TIM1_DeInit(); TIM1_TIxExternalClockConfig(TIM1_TIXEXTERNALCLK1SOURCE_TI1,TIM1_ICPOLARITY_RISING, 0x00);//(TIM1_CH1) TIM1_Cmd(ENABLE);

Hello, i use stm8l-discovery board with stm8l152c6t6.I need to sniff swim protocol and wrote the asm module for this purpose.This module uses WFE instruction to wait PIN transition and TIMER4 for timeout.If I use WFE for TIMER4 or PIN from only 1 source at a time then it works fine.If I useWFE for both sources then debug connection losts and reset occurs.Is there any way to workaround this issue?

Hi :) I am using an STM8L151G6U6, and found out I missed something in the datasheet.Datasheet is DS6372: https://www.st.com/resource/en/datasheet/stm8l151g6.pdfRM is RM0031: https://www.st.com/resource/en/reference_manual/cd00218714-stm8l050j3-stm8l051f3-stm8l052c6-stm8l052r8-mcus-and-stm8l151l152-stm8l162-stm8al31-stm8al3l-lines-stmicroelectronics.pdfIt seems that for the the 28-pin or 32-pin packages ("Gx" or "Kx" model number) it is not possible to use the DAC output buffer?Section 9.3.13 12-bit DAC characteristics of the datasheet (pages 105 & 106) shows th

Dear experts,I have a problem with stm8s_conf.h file. I download the Standard Peripheral Libraries officially from ST web page. After I put them all into STVD, I mean the .c and .h files, then I compile. The compiler detects that stm8s_conf.h does not exist. I try to check the stm8s_conf.h from SPL and thats true. I could not find the stm8s_conf.h file. So, I have to find it from another sources like github or something else. Back to the question, Is the stm8s_conf.h really exist ?Thank you & best regards,Mahendra

So I'm trying to scan channels from IN0 to IN6 in my stm8s-discovery board. At the same time, i'm using PE6(IN9) as a digtial input. When I debug, I've seen the PE6 works as digital input till I configure the ADC in scan mode.Using the stm8s cube with the mentioned configuration, a conflict warning is set in the adc peripheral: Is this configuration wrong? What if I scan IN0 to IN2, can I use PB3, PB4, PB5, PB6, PE6 and PE7 as digital inputs?
