JP1 Remotes

Hello all and thanks for reading.

I am still very green when it comes to JP1 but find it quite addictive
and after finding an old URC-7541 remote behind the "Wicker Whatnot" I
decided to try and extend my learning by trying to build the JP1 eeprom
interface using the Arduino 2560 here (using the appropriate SCL, SDA pins for this model)

Using IR version

Code: Select all

Remote Control Programmer
Version 8.04

Learned Signal Decoder: DecodeIR (Version: 2.41)

ExchangeIR Version: 0.08

JP12Serial Driver Version: 0.16

I get :-

Failed to open JP1.x interface.

However when I follow one of Tommy Tylers fantastic documents here using Realterm
https://www.hifi-remote.com/forums/dloa ... e_id=7959

I get this response back in the terminal

JP1 EEPROM Programming Adapter
Copyright 2010 Kevin Timmerman
Ported to Arduino 2012 Tim6502
Rev 003 Config 08 1

d Display EEPROM contents
f Fill with FF
z Fill with 00
t Fill with test pattern
4 24C04
8 24C08
6 24C16
3 24C32

and if I press "d" , I get all the eeprom contents.
I feel that I am quite close to using this interface but something is eluding me "RTS" possibly?
I have also tried RMIR 2.02a with no success in finding the remote.

Windows 7 64
Arduino 2560 r3
URC-7541

Thanks in advance for any pointers/suggestions
