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...
