Sparkfun Thing Plus stm32f4 i2c bus hangs slave mode

[hareshel]

Hi,

Programmed sparkfun thing plus stm32f4 i2c bus in slave mode and sending the serial data to the i2c bus. The bus is hanging after some point of time.

 

Any help will be appreciated.

 

Thanks,

Please give more detail on that.

Show your code: How to insert source code.

If it's a slave, what is the master?

Please show your connections.

What debugging have you done so far?
