The SAADC is triggered by TIMER + PPI, and samples are collected into a buffer and sent periodically. At around 1 kHz, it works relatively well, but whenen-USTelligent Community 13Mon, 23 Mar 2026 13:19:02 GMThttps://devzone.nordicsemi.com/thread/563879?ContentTypeID=1Mon, 23 Mar 2026 13:19:02 GMT137ad170-7792-4731-bb38-c0d22fbe4515:96962a58-8dd5-4d7d-9ef4-f50774487854Vidar Berg<p>Hello,</p> <p>I quickly made a small demo&nbsp;sample with good help of my coding agent that demonstrates how you can transmit 10k samples per second.
