# atsamd & atsame support for Rust

This language makes the PIC32CX SG feel really "bolted on", maybe something like "working with Microchip SAMD family of devices including SAMD11, SAMD21...PIC32CX SG."

"This repository holds various crates that support/enable working with Atmel (Now Microchip) devices (samd11, samd21, samd51 and same5x), as well as Microchip's own PIC32CX SG series using Rust "

sound better then?

(We could change this into a list, to better future proof this if we eventually get around to 1 day adding the next generation PIC32C series of ICs)
