Experiments with the Atmel SAME54P20A

some code I hacked together for a project I'm working on. i've since switched to a ST micro.

#features

• serial console with forth interpreter (zForth)
  • ADC dump command
  • memory dump command
  • set mux command (for external signal muxing board implemented with 74HC595 shift registers)
  • command history
  • dump module statistics
• ADC with DMA
• OLED display driver (character display only)

#bugs

• uart buffer mgmt code is lossy
• adc/dma code lives in main (i think I lost a commit where it had its own file)
• uses Atmel's START pile. (ugh, the low-level ADC and DMA stuff is so bad)

Anyhow, maybe it's useful and maybe it's not. Posted mostly for my own reference.
