History
MrJake222 576577fcb5 Fixed 10ms per-byte delay 
Replaced call to getchar with delay 0
Now "timeout" is handled in main loop
Repl responds only to valid characters (not timeouts)

Default Firmware

Downloads: releases

  • A first USB-UART (#0) is used for the and a REPL command line interface for now only showing help message and version information.

  • A second USB-UART (#1) is used for mirroring everything between this USB interface UART TX on RP0 with ICE27, UART RX on RP1 with ICE25.

  • A third USB-UART (#2) is exchanging data with the main SPI bus onboard (doc).

  • A 12 MHz clock is exported from the RP2040 pin 24 toward the iCE40 pin 35.

  • An USB DFU interface allows programming through dfu-utils as shipped with oss-cad-suite.

  • An USB MSC interface allows programming the board by copying a file to an USB device (doc).

See the documentation for how to use them.
