It connects to a bluetooth gamepad, relaying controller input to the Pico, and acts as a WiFi access point to provide network connectivity.</p> https://blog.usedbytes.com/2021/01/m5stack-core2-early-impressions/ Sat, 16 Jan 2021 11:13:08 +0000 https://blog.usedbytes.com/2021/01/m5stack-core2-early-impressions/ <p>Just after Christmas I ordered an M5Stack Core2 (referred to as M5Core2 in many places) on a bit of a whim. I&rsquo;ve been annoyed about my lack of a self-contained rapid-prototyping platform, and the M5 hardware looks pretty good, and appears popular online.</p> <p>Historically I&rsquo;ve used original Mbed LPC1768 boards which I&rsquo;ve collected over time. However the &ldquo;old&rdquo; online compiler platform for Mbed is more-or-less unsupported now, and last time I tried the newer <code>mbed-cli</code> system, I had a lot of trouble setting it up.</p>
