STM8 MCUs

Incorrect example files are on the ST website for STEVAL-ISA164 STNRG388A digital controller eval board. If someone could create a simple example to fix missing Example 4 we would reward you for your time

I wasn't sure where to post this request for the STNRG digital control IC example files so I'm reposting in STM8 after getting no responses in Power Management or from technical support in a weekThere is a link to download 5 sample files for the STLU...

Hey guys, I want to controll motors via joystick. Unfortunately, when I connect joystick to my STM8S103F3 analogue pins it reads 800 in the middle position instead of 512.

As the result, the right side has very short run (it reaches 1023 in one sixth of travel). The same for Y axis, the same with another joystick. Both joysticks work properly with arduino - middle 520 (or so). Is there any (obvious) reason; how can I r...

MCU restarts after I2C->CR2 |= I2C_CR2_START; during setting I2C_GenerateSTART

I am trying to get I2C communication working between two STM8S003F3P6.From I2c master I am trying to initiate I2C start message using CR2 registers with below code#define I2C_CR2_START ((uint8_t)0x01) /*!< Start Generation */   .....   I2C->CR2 |...

STM8S I2C master crashing on I2C_GenerateSTART(ENABLE);

I am trying to run example code for i2c master and slave, provided in Stm standard peripheral library from https://www.st.com/en/embedded-software/stsw-stm8069.htmlBut the master keeps crahing at I2C_GenerateSTART API call.I2C_ITConfig enableInterru...

How to check open drain pins PB4 and PB5 working properly for I2c communication [STM8S003F3P6]

I am trying to get I2C working for STM8S003F3P6 with ESP8266. I tried I2C sample code available with standard periferal library https://www.st.com/en/embedded-software/stsw-stm8069.html . But for some reason I2c is not working. Now I just noticed the...

On the STM8L101F1U, some IO port register bits do not have actual pins on the package. How should these register bits be initialized? Should I set them to input pullup, output or just input floating? Note: Part does NOT have COMP_REF.

What happens if PA1 bit is set in PA_CR1 on STM8L101F3U? According to manual, NRST has a permanent internal pullup - is bit 1 in the PA_CR1 register a "don't care" or does the internal pullup only matter if RST_CR==0xD0?

How can this code be simplified?

Can the TIM1 part of this tutorial be simplified as follows?https://embedded-lab.com/blog/continuing-stm8-microcontroller-expedition/6/Remove everything related to the the interrupt, because TIM1_GetCapture2() can be called at any time from main(). I...

What is going on with this PWM output timer 2?

I am following this tutorial and trying to get a complete understanding of the code:https://embedded-lab.com/blog/continuing-stm8-microcontroller-expedition/6/I have a few questions regarding the TIM2_setup(void) function:1 Why is channel 1 and chann...
