Hi,

I'm trying to write a driver for i2c communication for the Stm8L discovery board.

After the Start (Master mode) is generated if I try to send an adress nothing happens and the i2c clock is hung at low level.

I an using  high speed internal clock and i2c at 100kHz.

Does anybody has an idea?

Many thanks,

Felix

HI felix 

Please post some code. 

Be aware on the STM8Lxxx peripherals you need to enable the clock before anything will work!
