https://devzone.nordicsemi.com/f/nordic-q-a/89463/nrf-52833-interface-with-pn532-with-i2c-interfaceHI, I am a newbie with NORDIC semiconductor. I am working with nRF52833 and working on NFC reader with PN532 using I2C interface. I can find libraries with SPI and UART but not with I2C. Can you some one help me in getting the I2C libraryen-USTelligent Community 13Thu, 30 Jun 2022 06:39:47 GMThttps://devzone.nordicsemi.com/thread/374828?ContentTypeID=1Thu, 30 Jun 2022 06:39:47 GMT137ad170-7792-4731-bb38-c0d22fbe4515:504bc799-4dfb-4be4-9bb6-f707acef8345Simonr<p>Hi</p> <p>I2C is not the best choice to use for communication between NFC readers and the nRF52832, which is why we don&#39;t have a specific example for it, as it might not provide enough bandwidth&nbsp; if you need to do roundtrips between the nRF52833 and the PN532. I would recommend use a faster SPI at 4 or 8MHz, but it should also work with the I2C. The libraries you&#39;re looking for are the <a href="https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.1.0/group__nrf__twi.html">TWI drivers</a> in our SDK, as TWI is the same as I2C.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
