From 733094aead6e84b42da54655b2b0a5d0dbd1a503 Mon Sep 17 00:00:00 2001 From: Scott Shawcroft Date: Wed, 20 Jan 2021 16:47:18 -0800 Subject: Add initial RP2040 support The RP2040 is new microcontroller from Raspberry Pi that features two Cortex M0s and eight PIO state machines that are good for crunching lots of data. It has 264k RAM and a built in UF2 bootloader too.
