Example code for STM8S003F3

I am working with STM8S003F3 in our custom board . I need to communicate with an transceiver through SPI. I need a sample code for configuration of SPI in master mode and write /read process in SPI. Pls support by providing sample project.

Hi, L6387ED is used in STM's B-G431B-ESC1 which uses 3.3V logic when the L6387ED is only rated for 3.6V minimum high level logic threshold. Can L6387ED be reliably used at 3.3V? Please see additional details below.

The L6387ED datasheet indicates that the high level logic threshold is 3.6V as a minimum. https://www.st.com/resource/en/datasheet/l6387e.pdf#page=7The STM ESC eval kit (P/N: B-G431B-ESC1) definitely uses the L6387ED. We checked schematics and a some...

Can someone please suggest a direct replacement for a BUX98A transistor? I have attached a photo of 3 that I need to replace with a new model.

This is a discontinued model, and only 1 has the model number BUX98A printed on the body. I do not know what the other markings mean, and I would like to know if anyone does know what they mean.

USART Communication with PC (stm8al3l68)

Hello,I'm trying to implement serial communication between a stm8al3l68 an a serial terminal installed on my PC.The problem is that there is no virtual port on my STM8 as on STM32.How can I communicate with the PC if there is no virtual Port. What ki...

L9651 Low side switches - SPI compatible interface

Hi,the chip L9625 has a serial interface, but is this compatible with the SPI protocol?Moreover, is possible to use SPI commands to drive the outputs?Is there a more detailed documentation of this component?

Power Draw with ADC on STM8L152C6

I'm attempting to program this chip to act as a thermometer that can run on a low power solar panel. The issue I'm having is the power draw is way too high. Halted i have the power draw with an LCD and RTC interrupt ready at 5.5uA, but when I'm using...

Hallo, i need the Failure Rate or the MTBF - Mean Time Between Failures values from SM15T220CA and SMCJ48CA-TR. Maybe could you help me. Best regards

About TIM1 in STM8L series. I have been trying default PWM testcase available by STM for modulating Duty channel and frequency. I change values of TIM_PERIOD and CCRx_Val. I only see frequency changing. For some reason I observe only 50% duty cycle.

For some reason I am not able to see pins behavior in plotter. I am not able to see PD 2,4,5 output on plotter on STVD tool.I got the testcase from https://www.st.com/content/st_com/en/products/embedded-software/mcu-mpu-embedded-software/stm8-embedde...

Stvd newbie

I've generated an output file from STVD in .elf format. But stvp requires motorola hex format. Do I have to do another conversion?

Is there an 8-bit USB with HS or 3.0 USB MCU?

I found that the ST72681 8-bit MCU has HS function. Do you still support this MCU? Or is there a related follow-up product?Looking forward to your message​
