https://devzone.nordicsemi.com/f/nordic-q-a/40171/twis-minimum-scl-frequencyHi What is the minimum clock frequency that the TWIS module will work with? Obviously the I2C spec minimum is about 100kHz however the device I am communicating with is using a clock of 30kHz. There is no way to speed up this device.

If you decide to test/use other frequencies, this will be at your own risk.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/236381?ContentTypeID=1Tue, 25 Feb 2020 19:46:30 GMT137ad170-7792-4731-bb38-c0d22fbe4515:39c4251d-0311-4749-b181-e3ec7b2a359fEnovateCam<p>Has any testing been done at lower than 100 kHz?&nbsp; Should the TWIS peripheral be expected to work properly at 50 kHz or 25 kHz?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/156024?ContentTypeID=1Mon, 05 Nov 2018 17:03:43 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e32089dd-71b1-4070-a814-0933a364c047J&#248;rgen Holmefjord<p>Hi,</p> <p>The TWIS peripheral have a minimum bit rate (<a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52832.ps.v1.1/twis.html?cp=2_1_0_33_9#unique_1347530288"><span>f</span>_TWIS</a>) of 100 kbps.</p> <p>Best regards,<br />Jørgen</p><div style="clear:both;"></div>
