How can we do with the System incompatiblehttps://devzone.nordicsemi.com/f/nordic-q-a/22175/how-can-we-do-with-the-system-incompatibleI used to do with the iso7816 run on nRF51822 SDK9 and S110_v8.0. However,as the BLE stack is running, the iso7816 interface clock signal is abnormal. as the picture below,notice：the iso7816 clock signal was create by the PPI with GPIOTE and timer. theen-USTelligent Community 13Mon, 22 May 2017 09:10:41 GMTRE: How can we do with the System incompatiblehttps://devzone.nordicsemi.com/thread/87172?ContentTypeID=1Mon, 22 May 2017 09:10:41 GMT137ad170-7792-4731-bb38-c0d22fbe4515:bb8ef658-9d1f-4e3b-9748-05acfe0ccd58LIANGTAO<p>Thank you very much ！ I solved it just now</p><div style="clear:both;"></div>RE: How can we do with the System incompatiblehttps://devzone.nordicsemi.com/thread/87171?ContentTypeID=1Mon, 22 May 2017 09:06:57 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ab759cdb-3412-4450-86ab-34a0720967f8FormerMember<p>What does your code for generating clock signal using PPI and GPIOTE look like?</p><div style="clear:both;"></div>
