Editing Frontend usart interface

[[Category:Index]]

USART protocol for talking with frontend

== HELP ==
- debug command, prints out command and description of usage for all commands registered

Example format (THESE ARENT REAL COMMANDS)
 help: prints command output and description for all commands
 dump_debug: starts writing raw adc data to terminal
 listknownmessages_gui: returns a list of indices of messages the board knows about


== list_indicies_of_known_messages ==
A returns a space separated list of indicies of every index of every known messages. Each message recieved/put out gets a per-board index.

Example format
 list_indicies_of_known_messages                <= command to stm
 4 5 6 7 8                                      <= from stm

== print_message [int n] ==
Prints a pgp-like formatted message stored in the stm's memeory

Example format
 print_message                <= command to stm
 5                            <= command to stm
 this is my message
 you can't have lines over 40 chars
 or lines with a pipe
 but that's okay|                          <= text from board, raw text of message, | terminated

== send_message_to_board ==
Puts the board into uart multi-line receiving mode, interface will send the string content of a message, maybe format it to handle required feilds.

Example format
 send_message_to_board                <= command to stm
 0010                                 <= recipient id, sent from gui to stm
 this is my very cool message
 it contains a couple of lines
 and some fun smiles :) :p|           <= text to stm, raw text of message, | terminated

The gui will then write out the message content to be sent out by the board

== load_callsign_into_board ==
Puts board into one line uart receiving mode, then the gui enters a callsign as text, to be sent out at the end of each message per fcc

SUBJECT TO CHANGE! WE probably don't feel like writing a ascii => morse thing then a manual beeper, we may want to hardcode that
Example format
 load_callsign_into_board        <= command to stm
 aadaaa                          <= callsign as text sent to stm from gui controller
 

Notes:
 - serial number id is hardcoded
 -
