 I have implemented a hx711 sensor readout with PPI, using SPIM and PWM peripherals. But for this is needed 4 GPIO and one external OR Gate. I wait for a LOW pulse on AL_SPIM_MISO_PIN, and Read SPI data and disable pulse detect. When SPI RX end,</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Thu, 17 Oct 2019 11:23:16 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/53358/hx711-communication-ppi-spim-pwm-how-to-improve" /><item><title>RE: Hx711 Communication.

&lt;p&gt;Yes I did.&lt;/p&gt;
&lt;p&gt;But Vidar implementation don&amp;#39;t use easyDMA.&amp;nbsp;It&amp;#39;s not completely automatic.&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;I wonder if there is anyway to eliminate OR gate or ALT_SPIM_MISO_PIN.&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;Thank you for your reply.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Hx711 Communication. PPI, SPIM, PWM.

&lt;p&gt;Have you seen &lt;a href="https://devzone.nordicsemi.com/members/vibe"&gt;Vidar Berg&lt;/a&gt;&amp;#39;s implementation from &lt;a href="https://devzone.nordicsemi.com/f/nordic-q-a/40271/timer-issue-with-hx711---stopped-by-vector-catch-error/156552#156552"&gt;this post&lt;/a&gt;? It uses fewer pins and does not rely on any external components.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
