https://devzone.nordicsemi.com/f/nordic-q-a/33491/two-i2c-slaves-connected-to-nrf52832Dear Sir, I want to access two slaves viz. MAX30205 &amp; LIS3DH by using nrf52832. The problem is, as per the datasheet the values of the pull up resistors required by both the slaves are different. Max30205 needs 4.7k &amp; LIS3DH needs 10k. So what valuesen-USTelligent Community 13Thu, 19 Apr 2018 14:10:18 GMThttps://devzone.nordicsemi.com/thread/129007?ContentTypeID=1Thu, 19 Apr 2018 14:10:18 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b0e1b95c-bd14-43d7-8396-a628960f262eStian R&#248;ed Hafskjold<p>It is hard to give an exact answer to this because it depends on several factors. The driver strength on each of the slaves, the line capacitance, etc. </p> <p>You should check with a scope to see if the driver strength on the slaves are good enough to drive the pull resistor down, and that the pull resistor pulls the line back up again fast enough, for both of the slaves.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/128993?ContentTypeID=1Thu, 19 Apr 2018 13:22:08 GMT137ad170-7792-4731-bb38-c0d22fbe4515:72da55d7-dfa3-4717-9b98-5e8949b129a5Manoj Hiwarkar<p>I am using 100khz</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/128989?ContentTypeID=1Thu, 19 Apr 2018 13:11:56 GMT137ad170-7792-4731-bb38-c0d22fbe4515:058eb8a6-45f1-4e9a-9a3e-9f971a76be6dStian R&#248;ed Hafskjold<p>What is the bus speed you are going to use? You will probably be fine with just the internal 13k pull-up on the nRF chip for lower speeds.</p><div style="clear:both;"></div>
