Hey I too is running into the same trouble you are having. Can I ask you what chat pad you have. Is it the white and gray one with the PIC/Microsoft chip or is it the black one with gray buttons. If you look around the internet all the people that have had success with there chat pads have been using the black and gray one.spydergto wrote: ↑Mon Feb 08, 2016 7:59 pmHi not sure how old this is now ?
ive done all this and still no chatpad , theres another guy working on something similar to me over on hackaday.io and he has the same as me.
Ive got 4 wires with pin headers on the cables two wires soldered a 1k onto inline , RPI B+ i checked the pins ive wired chatpad rx to tx pi and chatpad tx to rx pi , i did your instructions step by step , i also read here and changed the file , it was default for 250 but it didnt work so i set it to 250 still didnt work ,
i ran your grep and two instances were there, root and users
i saw somewhere else i thought it was here but you mentioned a config file and editing the gpio pin headers to leave 14 and 15 , i did that too , still nothing ,
im stumped but i refuse to give up , at first i though you had flashed the other firmware with a pickit2 which i now have from chain post in my possession so even a usb to rs 232 idk how this thing ends up working i want the chatpad ...
can anyone help me peas ?
I can't speak for the Pi software / driver being discussed here but I have just completed a project to interface a microcontroller to Chatpads and that is all working fine using Microsoft manufactured Chatpads; White/Grey X814365-001 and Black/Black X852479-001.
