I2C- SCL & SDA pin change!!

[HPC]

Hi

In my custom project I'm using pins P0.14 as SCL and P0.15 as SDA . I know the pins selection #define is in twi_master_config.h. But the question is whether I have to use twi_hw_master.c or twi_hw_master.c for this pin configuration?

Do I have to do any extra configurations other than this?

Regards HPC

Hi,

I found the answer myself

According to nRf51822 Reference Manual, The different signals SCL and SDA associated with the TWI master are mapped to physical pins according to the configuration specified in the PSELSCL and PSELSDA registers respectively so the pins configured in the register are mapped to the TWI/I2C hardware inside the board

I couldn't find the twi_master_config.h file, where it is?

Define it by yourself.
