This crate abstracts target initialization and configuration, implementing traits from the embedded-hal crate for the ATSAM3X/A family of Atmel MCUs.
Target support:
| target | progress |
|---|---|
| atsam3a4c | untested |
| atsam3a4c | untested |
| atsam3a8c | untested |
| atsam3x4c | untested |
| atsam3x4e | untested |
| atsam3x8c | untested |
| atsam3x8e | simple applications running on Arduino Due |
| atsam3x8h | untested |
Peripheral support:
| peripheral | support level | notes |
|---|---|---|
| PMC/SUPC | clocking only | known issue affecting PLL configuration |
| MATRIX | SYSIO control only | allows switching ERASE pin to PC0 |
| SYST | Delay (sleep) support | |
| EFC0/1 | Configure op cycle time only | |
| PIOA-PIOF | switch between periph A/B/GPIO, pin config, driving/reading | |
| WDT | mostly complete | only disablement has been tested |
| UART | serial RX/TX, no hardware flow control | Only TX tested |
| USART | none | trivial to add serial RX/TX |
Many thanks to Michal Fita of the atsams70-rust project, and Wez Furlong, Paul Sajna, Michael van Niekerk, and Jesse Braham of the atsamd project. I have learned so much by studying how these projects support other Atmel SAM target families, and I wouldn't have been able to do it without their work.
