Stylus<p>Soon your RP2350 will be able to do graphics & text mode in Arduino using a new library I've been working on for <span class="h-card" translate="no"><a href="https://mastodon.cloud/@adafruit" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@<span>adafruit</span></a></span> -- I've created a wrapper around the DVHSTX library by <span class="h-card" translate="no"><a href="https://rebel-lion.uk/@mike" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@<span>mike</span></a></span> that enables the 16-bit and 8-bit graphics modes as well as the 91x30 cell, 7-color text mode.</p><p>This library is a lot more full featured than what I would have been able to achieve on my own, so big thanks to Mike for open sourcing it!
