OpenGD77

Since I am just starting to look at the firmware and CPS, I wonder it there is a diagram of the memory layout of the device(s). Don't get me wrong, if one does not exist, I would be more than happy to start a shared Google doc or something to document these.

It seems to me that the closest radio to the GD-77 is the RD-5R. Would button mappings be sufficient, or are there electrical differences like you are finding with the DM-1801 ?

What gave me the idea is this file: https://github.com/rogerclarkmelbourne/radioddity_gd-77_cps/blob/master/CodeplugComms.cs where HID is definitely used to read and write to the GD-77. So I started my little JS project, and yes I am starting to get results from it. Yes, and I was looking into WebUS...

I was browsing through the CPS code, and it appears that one can read and write to targeted areas of memory separately. That a complete read/modify/write of everything is not required. Is this true? I have started a Javascript tool that can read the configuration of a GD-77 using node-hid. Reason I ...

Hi,
I'm Bob, a programmer in Austin, Texas and a lifelong ham. I bought a GD-77 just for trying this excellent firmware. If possible, I would like to contribute to this project.
