[chirp_users] How to analyse the memory map for a new radio type?
I am a new Ham, and I foolishly selected a radio that is not supported by CHIRP. (Yaesu FT-4XR). I wish to add support for it and its recent Yaesu siblings. I have successfully analysed the serial protocol and I can read and write the memory, but I don't know what to do next. Is there a HOWTO somewhere? If not, I can attempt to create one, but some guidance would be appreciated.
Hi Dan,
There is no silver bullet, on the chirp's wiki search for /'developer', there is a frew simple guide for developers.
I will suggest this steps to you:
1. Subscribe to the developers maillist chirp_devel@intrepid.danplanet.com 2. Setup a dev environment (clone the chirp repo, dev wiki page has info about it) 3. Search on similar radios from the same OEM (Yaesu) usually OEMs tend to make one simple protocol for many radios, and you then need to tweak only the mem part, that also tend to be reused also. 4. Decide if you it worth creating a new drivers or reusing some of the actual code (Yaesu has a lots of reusable code) 5. Start coding 6. Don't hesitate to ask question on the dev list, may be you became the next Yaesu Guru for Chirp! 7. Funny, I was called recently by a user the 'Chirp's Kenwood Guru' ;-) on the chirp's wiki (not a guru at all, just hard work)
Happy hacking and Holiday, HNY to all.

Hi Dan
Please, first read this page: https://chirp.danplanet.com/projects/chirp/wiki/DevelopersProcess
I'm currently reverse engineering Yaesu FT-8900's memory map using following procedure:
* I'm working this reverse engineering primarily in Ubuntu, as it is easiest for me to debug Python there, using the Pycharm IDE. * Check out Chirp's repository using Pycharm's own Mercurial support. * I have created two spreadsheets for helping this development: o First one, where I'm maintaining settings areas as horizontal rows and configurations (readouts from device) as vertical columns. Sample: https://tuulos.org/nxld/index.php/s/5ELcBBKPqFGfZk2 (link valid till 14-Jan-2019) o Second one, where I'm writing out memory areas, which I have reverse engineered, if I'm not writing them directly to Chirp memory maps. * I'm making small changes to device configuration and creating a new vertical column, where I'm documenting the change. Then, I'm reading out the memory map from device. * I'm converting the memory map dump to text file using standard Linux hexdump command. Each vertical column has its own text file. * Meld is practical tool to compare those hexdump files. Using that, it should be possible to isolate, which memory areas were affected by device configuration changes. * After finding out, what was changed and how, I'm implementing support for those, by expanding the earlier implementation.
This is a pretty time consuming process, but so far, I have been able to isolate some new device settings/configurations and bring them to Chirp. Most likely, this will take still at least couple of weeks before I'm able to publish my changes.
BR,
Kalle
