I’ve looked at the code by a pull from Github and I think that a completely new function call for the GPIO could be called during SDRAngel’s normal operation by polling it at a convenient spot in the overall implementation. Obviously I would have to consult Edouard (@F4EXB) about this - but your biggest ‘bang for the Euro’ would be to send Edouard the same board and have us collaborate on it - Edouard from a code perspective and I can do a hardware implementation for it for bandswitching, PTT, and PA control - this is something I’ve wanted to do, but had planned to do that via LattePanda’s Arduino hooks. But this puts a completely new spin on all that.
Again, if you send Edouard a board for his use, and I get a board for HW implementation, THAT would be a incredibly great post and would finally attract everyone to it…But @9a4db (Djani) is right…Price may have to be adjusted a little to bring the hoard of Hams clammering to buy them.
Bring it on, Andrew…!!
