STM8 MCUs

Hi i am starting firmware development on STM8 based MCU. For that in need Cosmic C compiler but after its installation , for generating the key when i choose option "on the web"it does not send any mail to my registered Email address and if i choose "By Email" , then it shows that no mail is added to my profile.I dont know what to do next nor their are many articles on it over internet.Will be waiting for some valuable suggestions and help as soon as possibe

Hello Guys,I have a small problem in my STM8L device. My current remains in 30µA even in the halt mode (I would like to obtain 10-15µA). What are the ways to drop this value? I have tried to put a serial resistor to increase the total resistance of the system and finally to obtain lower current. However, if I use a bigger resistor than the 500 Ohm, system will not work. Is it a good idea to connect a serial resistor to the microprocessor in order to decrease the current? Will it has an impact on a bad way?I also tried to make some configuration changes in the code, like putting the halt mode or disabling the timers.In the below, you can see my main code.So, What do you suggest me to handle this problem?#include "stm8l15x.h" #include "stm8l15x_TIM2.h"   void main(void) { TIM2_CtrlPWMOutputs(DISABLE); TIM2_Cmd(DISABLE); TIM3_Cmd(DISABLE); TIM4_Cmd(DISABLE); ADC_Cmd(ADC1,DISABLE

STM8S001j3   SWIM PIN Not work, After hex file download (IAR EWSTM8 Compiler)8 pin port (SWIM) How to do in the firmware IAR.-DATASHEET 12page-Recommendation for SWIM pin (pin #8) sharingAs the NRST pin is not available on this device, if the SWIM pin should be used with the I/O pin functionality, it is recommended to add a ~5 seconds delay in the firmware before changing the functionality on the pin with SWIM functions. This action allows the user to set the device into SWIM mode after the device power on and to be able to reprogram the device. If the pin with SWIM functionality is set to I/O mode immediately after the device reset, the device is unable to connect through the SWIM interface and it gets locked forever. This initial delay can be removed in the final (locked) code.

Hi , i try to run the CLK example from STM8L15x_StdPeriph_Examples, but i can't compile the project successfully , below is my procedure, can you help it?create a new workspace using STVD tooladd the source and head files from the STM8L15x library folder compile the projectbut it show the error during the process, below the snapshot about the errors

Hi :)So I've been using the lovely software provided by ST, called ST Visual Develop, which is, not only one of the worst IDE I have ever encountered (I quickly switched to writing the actual code in another editor), but also is full of so many bugs.It got to the point now that I can literally create an empty new project, add my files and the program crashes every time. I also try added empty files - which works - but when manually copy-pasting my code in it the program crashes again. I also tried copying small bits at a time, but I cannot really identify which bits makes the program crash.Anyways - sorry for the rant - point is I am only using the program for debugging, so I was wondering if there are other alternatives?CheersSimon

the STM8 bootloader manual (UM0560 rev10) appendix B describes fewer families/bootloader versions than the erase/write RAM routines bundled with the FLASHER-STM8 v2.8.0. Specifically the newer BL versions

hi friends i asked my question just a few days ago but nobody answerd i dont know what should i do when i configure micro controller for cco output it generates out put of course its a little unaccurate when i check that is cco stable by checking CCORDY flag it remains in while loop for ever and flag CCOBSY is set forever and CCORDY never set ,itested it on two diffrent stm8s series result was same,i also check code with debugger ccor will remain 0x69 , i work with cosmic compiler and stvd environment. this is my code: #include "STM8S.h"#define LED_pin GPIO_PIN_0#define LED_port GPIODvoid setup(void);void clock_setup(void);void GPIO_setup(void);void main(void){ setup(); GPIO_WriteLow(LED_port, LED_pin); while(TRUE){};}void setup(void){ clock_setup(); GPIO_setup();}void clock_setup(void){ CLK_DeInit(); CL

Cosmo has no space limited version, you can download it there, thank you!

I created a program on STM8S103F3 to generate a delay in rage of micro seconds using TIM2 module, but the timer is not ticking as expected and when I tried to call 1 sec delay using it, it is giving around 10 sec delay. I'm using 16MHz HSI oscillator and timer pre-scalar is set to 16. please see my code below. Please help me to figure out what is wrong with my code.main(){     GPIO_Init(FAN_PORT , FAN_PIN, GPIO_MODE_OUT_OD_LOW_SLOW ); // Need to change mode to push pull GPIO_WriteLow(FAN_PORT , FAN_PIN); Serial_begin(9600); //Initialize Serial communication at 9600 baud rate Serial_print_string("\r\n>>>>>>>>>>>>>>>>Board Up and Ready<<<<<<<<<<<<<<<<<\r\n"); //print a string while (1){    GPIO_WriteHigh(FAN_PORT , FAN_PIN);    delay_ms

Here I am using the STM8s003k mcu .In my application,I am configuring the external interrupts for a port .after rising the interrupt how can I clear that interrupt.If I can not clear that interrupt the external interrupt handler only will execute. I am not able to execute another functions .please tell me how to clear the pending external interrupts

Hi,Reset is not happening at only particular project while debugging using STVD. But the same code is working fine if I load the code through STVP. Same MCU Reset is working fine with other project while debugging. I don't know is there any settings need to be changed in the STVD. I commented all the lines except CLOCK INTZ but still in that project, reset is not happening. If I manually short the RESET and GND pins means Reset is happening but through STVD not happening. Help me to solve this problem...MCU: STM8S003K3Regards,Nishanth M

Hello,I have got an industrial PCB with a STM8S207RBT6. I'm able to READ programm memory, data memory and option bytes with ST Visual Programmer and STLink V2.Also I can write data memory and option bytes. But if I try to write program memory I get an error:"Programming failed. Device is write protected. Check by values."But in by value I can't find anything about write protection. Only read out protection, which is turned off.Option bytes are set to:000102000000000000Any advice for my problem?RegardsChris

i tested it with below code and ieven change prescalers for lower and higher frequency , i also check it with external crystal (and change the code) but it remains in while(CLK_GetFlagStatus(CLK_FLAG_CCORDY) == FALSE);for ever . when i debug the code and step over in debugger environment after the programm enables CCOEN bit the out put will start and frequency is just true . but both flag CCORDY and CCOBSY remains set (CCOR=0x69 in debugger) and it always remain in while loop. my code is: #include "STM8S.h"  #define LED_pin                      GPIO_PIN_0#define LED_port                     GPIOD  void setup(void);void clock_set

Everything I'm seeing seems like it should be straightforward. But I have been through everything Google came up with and have tried as many pull up resistor values, configurations, and sequences as I could find and had no luck. Have tried STVD Light Programmer as well as STVP. ST Link V2 connection seems like it is right. (1 - VDD, 2- SWIM, 3- GND, 4 - NRST) MCU schematic is as follows:VDD(5V) -> 1uF to GNDSWIM-> Same results with both: 1. Connected right to ST Link or 2. Added ~750ohm pull up to VDD.NRST-> 0.1uF to GND. I am seeing different errors based on NRST configuration when trying to program through STVD light programmer. Error 1:<NRST just going to ST Link OR NRST pulled up to VDD regardless of Pull Up value> Error: Problem while trying to Reset swim and device. Apply a Power On Reset.

Hi =) I am using a STM8L151 but I am pretty sure this is the same for any STM8 with i2c.The register I2C_FREQR is described in:page 507 of the RM0031: https://www.st.com/resource/en/reference_manual/cd00218714-stm8l050j3-stm8l051f3-stm8l052c6-stm8l052r8-mcus-and-stm8l151l152-stm8l162-stm8al31-stm8al3l-lines-stmicroelectronics.pdf

hi,I am new to this stvd tool i want to use string comparison function can please any one help me thanks in advance

Hello Guys,I am using STM8L board and would like to learn how can I generate a PWM Signal at the output port with TIM2. How should I set the configuration?Thank you

Hello,I am new to ST processors. Here is the issue:I am trying to setup Timer 3 for interrupt, Code: TIM3_DeInit(); CLK_PeripheralClockConfig(CLK_PCKENR1_TIM3, ENABLE); TIM3_TimeBaseInit(TIM3_Prescaler_64, TIM3_CounterMode_Down, 2500);    TIM3_SetCounter(0);     TIM3_ARRPreloadConfig(ENABLE);       TIM3_PrescalerConfig(TIM3_Prescaler_64,TIM3_PSCReloadMode_Update);    TIM3_ITConfig(TIM3_IT_Update,ENABLE); TIM3_Cmd(ENABLE); The funny thing is that the call "CLK_PeripheralClockConfig(CLK_PCKENR1_TIM3, ENABLE);" does not turn the Timer 3 gate on. As a matter of fact it turns on gate for Timer 4.I had to use "CLK_PCKENR1_TIM2" to turn on the gate for Timer 3.I traced to the function and fund this line inside "CLK_Pe

Hello,I'm working on a project in which I want to generate some trigger output ( which is connected to a sound chip APR33A3). Hence, I'm using the controller STM8S003FS GPIOs to generate the trigger output. Unfortunately, for an unknown reason, some of the GPIOs are not working properly in the normal push-pull out mode. I've marked them in the Image attached below. The output of these GPIOs is staying unchanged (checked physically via multi-meter).I'm also adding the snippet of my code, so, if I made any mistake please let me know.The nor working pins are as follows:PA3 (HS)/[SPI_NSS] TIM2_CH3PD3 (HS)/AIN4/TIM2_CH2/ADC_ETRPD4 (HS)/UART1_CK/TIM2_CH1/BEEP/* Includes ------------------------------------------------------------------*/ #include "stm8s.h" #include "stm8s_conf.h" #include <stdio.h> #include <string.h> #include <stdlib.h> #include <intrinsics.h> /* GLOBAL DEFIN
