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 |...

I am trying to run simple program to output HIGH on IO pin of microcontroller STM8S003F3P6. I am using PB5 pin to output High. I am using 3.3v power supply and expect GPIO to output 3.3v when I set it HIGH but surprisingly I am getting 5V instead, b...

I see correct address gets generated in asm file below; src/main.c: 173: I2C->CR2 |= I2C_CR2_START; ld a, 0x5211 or a, #0x01 ld 0x5211, a Below is the interrupt handler defined , but I do not see that getting invoked as print ...

Thanks, it seems somewhere there was loose connection, but it seems to be working now
