can we use other pins as SDA and SCL for TWI other than 24 and 25?

hello everyone,

i am trying to use SDA and SCL pins of TWI other than 24 and 25, is it possible? i want to know before using other pins for twi other than 24 nd 25 with hardware not with software twi!

Yes it should be possible.

See section 27.2 in the nRF51 Series Reference manual. The pins to use are specified in the TWI registers PSELSCL and PSELSDA.

Disclaimer: I don't work for Nordic, and I have not tried this (although I will soon).

Good luck,

/Erland

Yes it is possible , in twi_master_config.h file you can select other pins than 24 & 25 for SCL and SDA . Please be careful for using UART pins because need to break the solder bridges for using it
