I2C support for microcontroller

[vineetn]

I was wondering if the standalone nRF51822 microcontroller has support for i2c. If so which pins are supported. There doesn't seem to be any reference on i2c for the board.

Hi

Goose is absolutely correct. The nRF51822 does support I2C (TWI). You can check out the specifications for it (and what pins can be used) in the Product specifications. We do generally recommend SEGGER Embedded Studios or Keil µVision, as that's the environment it's easiest to get support for. Keep in mind that the nRF51822 is a rather old chip, and the newest SDK that supports it is SDK v. 12.3 which is not supported by SES.

Here are some links on the various TWI (I2C) examples in the SDK v.12.3:

• TWI scanner example
• TWI Sensor example
• TWI Transaction Manager example
• TWIS Slave and TWI Master mode drivers example

Best regards,
