Function Documentation

decfloat read_digit __attribute__

(

(__section__(".bss"))

)

crude floating point data storage

this is where we store all the data for the current command before we work out what to do with it

void gcode_parse_char

(

uint8_t

c )

Character Received - add it to our command.

accept the next character and process it

Parameters:

c	the next character to process
