The Raspberry Pi Thread [3]

Soldered up my second Proto Hat with my shut down button circuit. Added the jumper wires and header for my 4 10mm LEDs too. I'll move that over to this Proto Hat. It's just 4 short jumper wires and a 4 pin header to unsolder and remove. Then edit my python file to add the shutdown code to it. Can't install it until I get my tall stand offs. It's not a big deal. I just take the clear cover off to shutdown. I have got to tell you, it sure looks a lot better without all the holes in the case. Live and learn.

I have a apt for my car on monday in sydney ,i will drop of the tall header i have ,i wont be using it any time soon, running it right now on the pi-zero on the phat stack ,but the zero will be in the way of the piano, just to many wires ... i will lend it to you till adafruit get them in stock....i also have a few other Free things i will likely never ever use ,and you might or ,might not ,i bring them too..andi wont take no for an answer ,,

I had 1 Proto Hat board, and 1 tall stacking header in my parts bin, so I'm good to go there. Assuming I don't build anything else in the near future. Thanks for the offer though. It's the tall 16 mm standoffs that I've run out of. My Pirate radio ate some up, I put a Proto bonnet in there with a stacking header to wire up my buttons. I think I used some on my Rover project too. Poor planning is all it is.

I COULD SCREAM. set the phat stack up following pimorni instruction , running on bootup ,piano lights LEd's when hitting keys ,but no sound ,drum hat works as expected with sound .......I removed it from the pi zero to a Pi2....more room

Looking at the pinouts the Piano Hat and Drum Hat don't conflict. Speaker pHat looks OK too, no conflicts with the other two, that I can see. They all use i2c but that's OK. Have you run all there together before? Namely the Piano and Drum Hat on the same Pi? Might be a software conflict. Other than physical layout I bet the electronics are very similar. Try just the Piano or Drum Hat with the Speaker pHat. One then the other. If they work separately then its a conflict when both are wired up.

How are starting everything up on boot up? One python file for each Hat?

Pimoroni created a bash file to run them both .just scroll down a bit on this page ..
Build an Itty Bitty Beat Box - Pimoroni Yarr-niversity

Ah, OK, all the hard stuff is done for you, cool. IMHO, Pimoroni is a big step up from what you get from Adafruit, tutorial wise.

So it's launched with crontab, which is what I expected.

Does the piano hat work if you manually run some of the examples? Did you clip and past that sh file stuff? I'd double check that file for typo's etc.
