Hello,

I am interfacing a stm8s003k3 MCU with 12c LCD but it is not showing any thing on display.

It is stuck on I2C-> SR! shift register which is showing 0 but it should be 1.

The i2c addres is 0x3F i have already checked the LCD with ARDUINO board it is workinh fine with the same address.

I have pull up the SDA and SCL line by 10K .

Please anyone help me out from this problem.

It should be very helpful for me.

Use first a SW emulated I2C master with GPIO, it's much easier to get started and break down challenges in smaller pieces.
