Hi. I am working out if I have the time (and effort) to look into the firmware support for the gps module and the nmea modules. I have had a quick look and would like to make some modifications, initially to support more messages. What would be the best forum to get help on/discuss code changes in the firmware module to do with the gps module shim. A lot of my questions will not be purely bug requests, or even support requests, just things like 'why is this here' or 'why not do this'. I assume a lot of my questions will already have been answered by the original authors, hence I do not want to create pull requests that get knocked back simply because its the wrong design.
