STM8 MCUs

Hi,I have been trying to interface stm8s003k3 with and external ic ​using spi in full duplex master mode .I have been successful to set up the spi in full duplex master mode but the part where recieving and transfering data becomes tricky and I have partially been able to get some data but I think it is wrong.

Hello,I have a LDF File with one Master and 2 almost identical slave nodes. The slave nodes only differ in name and ID. For example:slave_1 subscribs to slave_1_state and slave_1_position.slave_2 subscribs to slave_2_state and slave_2_position. Now I don't want to build two executables and flash them on two slaves. I'd rather build on executable and flash them on the slaves and then tell one after another which one of the slave it and which frames its suppost to subscribe.I think assing_*** or assign_frame_id_range are going in the right direction, but I can't figure out how exactly it is done. I'd be glad for every hint. Thank you for your help.

Our implementation of the SWIM protocol expects the "HSI clock is trimmed" bit in the SWIM CSR to be set after initialization. As UM0470 states, "At the end of the option byte loading, the HSIT bit in the SWIM_CSR is set by hardware."In a test with STM8AL3188, we are finding that sometimes HSIT doesn't get set - the entry sequence works, the CSR can be read, but HSIT is not set within 10 seconds. What could cause this? Does it mean that option bytes are not loaded, or does this relate to UM0470, page 10, item 9: "Depending on the target context since power on, the HSI clock could be not well calibrated in step 4"?

Hello,We have STM8S105K6T6C parts with same COO = Malaysia and same date code but some have MSL listed as 2 on the manufacturing label and the others have 3 as MSL. The question is which MSL is the correct one or they are both correct? I couldn't find any document to indicate what MSL should be. Thank you.

Hi,I am using window 10 version. Initially STVD was working well. Now from few days its not working. Automatically workspace get deleted, not generated. STVD starts not responding error. Automatically get closed. I am using COSMIC compiler.Then later, I have reinstalled the stvd , though I am facing same issue, Even no desktop icon is created

the DOS window says synchronization OK then gives a unknown exception then says ERROR and dosnt load code any ideas?

Hi =) Short version: should there be time (cycles) between updating ARR/CCR registers and generating an update event by setting the UG bit in TIMx_EGR?Long version:I am using one timer, which is automatically enabled (triggered) by another timer.I made sure that:The timer is not enabled and will not be started before the setup (lines below)Setting the UG bit will not call the interrupt (URS set in in TIMx_CR)Both ARR and CCR are pre-loaded (ARPE set in TIMx_CR and OC1PE set in TIMx_CCMR)Then I do:set ARR and CRR values into their preload registergenerate a UEV (UG bit in TIMx_EGR) to load the values into the shadow registersThen change again (right away) the values of the preload registers so that the shadows are automatically updated on the next UEVThen - later - the timer is startedI get very strange resul

Hello Dear,I am using STM8S105C6 microcontroller and want to toggle the GPIO, But I am not able to do this.Will you please help

I'm using STM8AF5288 and the COSMIC as my IDE.Everything working great accept for interrupts using.The interrupt are being fired as I accept but on returning from the interrupt the PC is out of the program memory addresses.It is happening with external interrupt as well as with UART TX interrupt.Anyone ?

I am trying to generate a delay in STM8s103 using Timer peripheral TIM2.but on equating the values to the Prescaler register(PSCR) and ARR. that is not happeninglike I debugged my code step by step and on seeing the values of TIM2 registers, they are not loaded with assigned values. below is oic for it.I am running my MCU at 2MHZ HSI and then using the PSC value for TIM2 be 1 so that my TImer frequency is 1MHZ and then generating delay of us, ms, and sec by using these functions#define PB_ODR *(unsigned char*)0x5005 #define PB_DDR *(unsigned char*)0x5007 #define PB_CR1 *(unsigned char*)0x5008   // Unsigned int is 16 bit in STM8. // So, the maximum possible value is 65536.   unsigned long int dl; // Delay #include <stm8s.h>       void timer_init(void) { TIM2->CR1 |= 1<<7; //ARR buffered   //Enable the update generation so that PSC and ARR can be loaded TIM2->EGR |= 1<<0; //Time

HI guys, i am using stm8s003f3.which have 10bit adc but my application count is more than 1024.so i am looking for some sample code of oversampling to reduce my adc step size.if anyone have any sample or reference plzz do suggest n tell me how to implement it in ssoftware with proper resolution.Thanks!!!

Hi,I am working with stm8s105c6 controller. I want to generate 6 PWM using timer1. For that I am using 6 step PWM sample. I am getting pwm at pc1, pc2, pc3 but complementry pwm at pb0, pb1, and pb2 is not available.At pb0, pb1 and pb2 I am constantly getting 5V Dc. why?will you plz help?Thanks

Hello everyone.I am in trouble with the SWIM pin of STM8S.According to the data sheet, unused pins should be set to OUTPUT.However, I would like to keep SWIM pins in a state where they are normally unused and can be debugged only when necessary.How can this be achieved?Thank you for your advice.�?Postscript】I supplement my questions.UM0470 has the following description.Perhaps I think that I can switch between SWIM function and I / O function with a jumper, but I don't know the internal settings to achieve this.In addition, when I / O is used, I want to apply unused-pin processing such as pull-up to the SWIM pin.(I

Hi all, I'm working on a part that has implemented something very similar to the ST-provided user bootloader for the STM8. I've tired uploading a binary using several versions of the STM flasher but none of them seem to work. Is there a script available intended to work with this bootloader?https://my.st.com/content/my_st_com/en/products/embedded-software/mcu-mpu-embedded-software/stm8-embedded-software/stsw-stm8006.license=1613127056306.product=STSW-STM8006.version=2.1.0.html#overview

Hello, I have looked in the datasheet and there is no "FT" like the stm32 family has. It does show that the UART pins are "HS" (high sink current). Can I assume there is something like a zener diode plus resistor to protect the core from 5 volts? That to me would be a reason why those pins are "HS". I will have a PL2303 USB-to-serial adapter connected to the UART, and it operates at 5 volts. Thank you in advance.

Hello, I'm using ST-Link / V2 to program STM8S001J3 with STVP (Swim connection). When I try to program MCU, the error appears that it was not possible to connect with the device. The pins are correct and I'm using 3.3V (Pin 19 to CN3 of ST-Link).Even if there is an error, the led turns green after programming.What is strange, I also use an STBM1008A for the same purpose and it works without problems.

Hi,I am using STVD to debug program for stm8s105c6 MCU. Here am able to compile code properly, and using cosmic compiler.I am getting error for Inline, and also prototype missing, semicolon missing, invalid constant expression, etc. errors are coming.Do they are occurring due to c language standard version or anything else?Please guide.Thanks in advance.

I am trying to use gsm module with stm32 to send sms. Which gsm library should I use?

Hello,I have to program STM8 device under Raspberry Pi OS. But I can't find any support page explaining how to use ST-Ling under RPI linux. Device is STM8S007C8T6 .It is not necessary that I have to use ST-Link, I only have to connect to and program/verify STM8 device, so every tool is acceptable.Any help is highly appreciated.

Please contact ST chip officials.Are there any plans to make STM8 series chips possible in STM32cubeide?

Hiii guys, i am using stm8s003f3.i configure it according to datasheet and it work almost fine,but problem is, it is generating random voltage when there is no input is connected and because of this input fluctuation getting unwanted output.how to make this adc value zero if there are no input connected,please help. here is my ADC initialization and ADC read code.....void ADC__Initialization (void) { ADC1->CR1_BitFields.ADON = 1; // Turn ON the ADC ADC1->CR2_BitFields.ALIGN = 1; // ADC data is right aligned ADC1->CR3 |= 0x00; //Disabling buffer ADC1->TDRH = 0xFF; // Disable High Schmitt Trigger ADC1->TDRL = 0xFF; // Disable Low Schmitt Trigger } float ADC__ReadChannel (uint8_t channel) { uint16_t val;   ADC1->CSR_BitFields.CH = channel; // Select the desired ADC channel ADC1->CR1 |= (1<<1); // Continuous conversion Mode. ADC1->CR1_BitFields.ADON = 1; // Turn ON the ADC do { _asm("nop"); _asm("nop"); _asm("nop");
