https://devzone.nordicsemi.com/f/nordic-q-a/21412/i2c-read-write-on-nrf24le1Hello, When using hal_w2_read() and hal_w2_write(), should the 7 bit address of the slave be passed in or the 8 bit read/write address? It seems to me that passing in the 7 bit address works in hal_w2_write().en-USTelligent Community 13Wed, 19 Apr 2017 06:49:41 GMThttps://devzone.nordicsemi.com/thread/83954?ContentTypeID=1Wed, 19 Apr 2017 06:49:41 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1135f363-5a3d-4c1b-b0ba-1e1e9355d1f4ovrebekk<p>Hi</p> <p>You just need to pass the 7-bit I2C address, not including the RW bit.</p> <p>The library will shift the address to the left and add the RW bit for you, depending on whether or not you call the write or read function.</p> <p>Best regards<br /> Torbjørn</p><div style="clear:both;"></div>
