https://devzone.nordicsemi.com/f/nordic-q-a/17245/software-i2c-for-nrf52832Hi, Is there any software I2c library or example projects for nRF52 devices (PCA10400) with pin configuration, read and write functions? I am using an SMBus based sensor and the inbuilt TWI drivers are not working. Thanks, Vishnuen-USTelligent Community 13Mon, 24 Oct 2016 09:07:07 GMThttps://devzone.nordicsemi.com/thread/66236?ContentTypeID=1Mon, 24 Oct 2016 09:07:07 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c118a17b-c7f2-449e-9bf6-20e27b6ca4c0Vishnu Pradeep<p>Thanks Kim, I&#39;ve tried with these examples and it was not working.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/66237?ContentTypeID=1Mon, 24 Oct 2016 07:50:03 GMT137ad170-7792-4731-bb38-c0d22fbe4515:57a5151c-f379-48ef-b6e3-b7fc47fe091bbjorn-spockeli<p>Hi Vishnu,</p> <p>I am afraid that we do not have any libraries for software I2C for the nRF5283. The GitHub repo that Steven Kim is referring to uses the TWI hardware drivers in our SDK.</p> <p>As far as I understand you should be able to interchange I2C and SMBus devices as long as you ensure that the clock frequency is set to 100 kHz.</p> <p>Best regards</p> <p>Bjørn</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/66235?ContentTypeID=1Sun, 23 Oct 2016 08:09:03 GMT137ad170-7792-4731-bb38-c0d22fbe4515:cd1ecbc4-ea89-4c08-b33d-a045ff7f1647Steven Kim<p>Hi!</p> <p>can are you check this git?</p> <p><a href="https://github.com/Martinsbl/nrf5-mpu-examples/tree/master/nrf52-mpu-easydma-using-timers-and-drivers">github.com/.../nrf52-mpu-easydma-using-timers-and-drivers</a></p> <p>and if you want more info check here</p> <p><a href="https://devzone.nordicsemi.com/question/69636/nrf52-twi-easydma-feature/">devzone.nordicsemi.com/.../</a></p> <p>thank</p><div style="clear:both;"></div>
