BATC ATV repeater logic software design
Posted: Sun Jan 02, 2022 6:20 pm
Prompted by the desire to replace the video switcher and logic on GB3HV, I put together a specification for an HDMI switched and repeater logic which Dave G8GKQ has decided to turn into the standard BATC repeater logic.
Based on the RPi 4 (of course) the software will control a video switcher either by RS232 or GPIO pins and will generate a carousel of images. On receipt of a valid signal from, for example, a Ryde receiver, it will switch to that input - when the receiver closes, the logic will play a key sequence, dekey the tx and go back to the carousel.
We recognise every repeater is different and so we intend this to be a core logic that can be used as the basis for your repeater. We have tried to think of the type of options users will want and Dave has put a lot of parameters in the SSH config file but we won't be doing specials! The code will be on Github so you can modify it to suit your own needs.
The requirement spec (attached) has only just been finalised and Dave has just started writing code - an initial release is targeted to be available at the same time as the next issue of CQ-TV.
