Structs

Command

ConsoleWriter

KernelAddresses

Data structure to hold addresses about how the kernel is stored in memory on the chip.

ProcessConsole

Constants

COMMAND_BUF_LEN

Commands can be up to 32 bytes long: since commands themselves are 4-5 characters, limiting arguments to 25 bytes or so seems fine for now.

DEFAULT_COMMAND_HISTORY_LEN

Default size for the history command.

QUEUE_BUF_LEN

Buffer responses are initially held in until copied to the TX buffer and transmitted.

READ_BUF_LEN

Since reads are byte-by-byte, to properly echo what’s typed, we can use a very small read buffer.

WRITE_BUF_LEN

Buffer to hold outgoing data that is passed to the UART hardware.
