Yeah. Some people have a hard time understanding unless they can see it.
Not me...not necessarily...the vid DOES explain very well what you wanted to say.
But for all the words and all the BOLD text, the conversation missed the target for me.
I can sorta see why digirig doesn't want to mention the words "RA Board"
Except they DO mention it, and that is what led to my initial confusion.
It's all written out in the Digirig Lite Setup Manual: <>
It doesna mention fldigi's setting "Rig Control > C-Media PTT"
and why you'd choose C-Media PTT when what you really want is to toggle GPIO3 on the chip. And explain why GPIO3 isn't special...GPIO pins are uncommitted digital signal pins. A lot of detail is not needed, but SOMETHING to help lay a base for learning. (I haven't looked into why pin 3 and not another. I assume some design decision by some folks somewhere....)
They DO mention "RA Board" and "CMedia GPIO3" in the PTT section, though.
Yes, they do...leading to my confusion about needing a board.
has one of the answers, but I needed to read 2 blocks to get the answer.
GPIO3 (RA-Board),
Each can be disabled via solder pads. &&&
PTT by VOX (enabled by default), PTT by GPIO3 (enabled by default)
I now understand this means that
1. Both PTT methods are enabled on the lite as shipped
2. Either method can be used without disabling the other ***
*** This is not stated. Nor is any reason given why one might want to disable one of them, if they can coexist without interfering with one another.
