[fpc-pascal] Interrogating external devices using USB

[BobJ]

Good morning all,

I have multiple amateur-radio transceivers which may be programmed with computer software through a USB cable connection.  There already exists various software applications to perform those tasks, however, most, if not all, are either inaccessable or very difficult to use by blind amateur-radio operators.

My goal is to develop software that is as easily used by blind amateur-radio operators as it is by sighted users.

I am a retired software developer so I believe I can develop a suitable user interface, however, I need to overcome two major challenges which I never encountered in my professional career.  I am hoping that someone out there can provide some direction as to where I can start mastering the two following challenges.

1. I have never written code to access external devices via USB connections.

2. I have no clue as to how to read/write to external devices for which no technical details are available.

I need at least a starting point which I have been unable to discover through several searches on the internet.

Any and all suggestions/assistance will be appreciated!  Thanks for your consideration!

73   Bob   AD8RJ
