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.

thanks. but in i2c we require slave address. can you tell me what is 7 bit slave address of nrf52??
