Re: missing lirc init

CrowPi v2 with the Pi 4B requires new version of drivers and these were not shipped on the MicroSD shipped with the unit. You have to (1) Download the updated CrowPi image from https://drive.google.com/file/d/1ZLW9xXooh-E7gQ0tKTVnSiIXHXc1O9O8/view?usp=sharing with the new drivers (2) If you haven't ...

missing lirc init

The init routine which should be in the lirc library isn’t. Reading comments under the video I saw others had the same problem and I have asked elecrow for a response which I will post here when I get it. I’m guessing it is related to the software upgrades since v1.0 which have mainly been beneficia...

Re: relay first timer

I found the problem. The v1 relay doesn't carry a voltage like the v2 relay does, which I knew. The points not made clear in video or docs are these: 1) Although Elecrow posted a relay video v2 on YouTube, the only difference between the two videos is a superimposed whiteboard in the bottom right of...

relay first timer

I can’t find a wiring diagram for the crowpi and blew a LED by connecting it directly to terminals 2 and 3 of the relay without putting a resistor into the circuit because I don’t know what voltage there is across the terminals or what voltage i should be putting on a LED. I have relay version 2 on ...
