TrinketM0 does not play sound?

by Kroran on Tue Jun 11, 2019 10:22 am

I remember the description saying it can play 10-bit audio but have not had any success in doing so.
Is this a malfunction with my board or do the trinkets just not play audio?
P.s have tried Arduino IDE and Maker Code

Can you share more info on how you're trying to play sound in Arduino and MakeCode on your Trinket M0?

First off (OMFG ITS JOHN PARK!!!! AAAAHHH).

Second I tried using the following code with a piezo speaker or an 8 ohm speaker
using Makercode I use
Code: Select all | TOGGLE FULL SIZE
music.setVolume(10)
forever(function () {
    light.showAnimation(light.rainbowAnimation, 1000)
    light.setAll(0x00ff00)
    music.magicWand.play()
    light.setAll(0xff0000)
    pause(1000)
})

and Arduin I use this old code I took from a forum
Code: Select all | TOGGLE FULL SIZE

ha! So I don't get any sound using the MakeCode Maker code either, I've submitted a bug: https://github.com/microsoft/pxt-maker/issues/234

I'll try Arduino next as well as CircuitPython.

The github issue is the best place to check for updates. https://github.com/microsoft/pxt-maker/issues/234
