nrf 51822 spi sensor applications

[pavan]

Dear all,

I am working on one sensor project(temp and accelerometer sensors) where our Nordic nrf51822 soc should read the data using spi protocol and transfer it to the smartphone app via BLE.. for this i have few queries

1. which pins can be used for SPI and I2C protocol?how to initialize the same?any example codes available ?
2. before designing the custom board can i try the SPI and I2c protocols on nrf51Dk?if yes how to configure the things ?

In nrf51822 production manual there is not much explanation pin configuration for SPI and I2C protocol like in nrf52 series Product specification manual .

Please share

1. Any pin can be used. Examples code are available in the SDK
2. Yes, you can. Configuration ? just wire the pin you use in your firmware
3. Yes, the is 2 chapters dedicated to SPI & TWI (I2C) in the nRF51 manual
