i2c in nrf51

[rushin]

hello there i have one nrf51 and other nrf52 kit. can we do i2c communication between these two microcontrollers??

[RK]

Yes. The nRF51 can be a TWI master, the nRF52 has both TWI master and TWI slave peripherals. So you can make the nRF51 the master, the nRF52 the slave and run communications between them.

You could also communicate with SPI between the two of them.

Whatever you like. Read the TWI Slave section in the manual which lists all the registers and things you can configure. The nRF52 slave will even answer to two different slave addresses if you like.
