Firmware explanation - lots of code is confusing

[robodude666]

Hey guys,

I have been looking through the SSC-32 firmware source code again to try and figure out how does jim get away with doing regex without actually using regex And im stuck!! There is a massive amount of code and its all around the place and I can’t keep track of stuff Does anyone here understand the SSC-32 code?

Reason I am asking is I will need a similar serial system where I can send characters to my PIC and it will execute different functions based on it. I could do the long if/ifelse/else statement but that would be a pain in the ■■■■ and using a large array seems quicker.

So far I understand that there is some sort of “rx_queue” and an array with all the commands and function that gets executed. What I don’t understand is where/how does the SSC-32 listen to the serial port to get incoming strings and parses them. And also where does the correct function get executed.

Thanks,

There is an interrupt routine for the tx and rx, these read a queue of chars sent either to or from the RS232. The main code calls process_commands and this takes each character and processes it.

I am trying to find a way of modifying the code to easily put things straight onto the rx buffer so that I can simply list my program in an array of strings “#5 P1600 T1000” style within the chip…

Antone got any ideas about that one, let me know…
