Only outputs Saw Wave
aframires opened this issue · 5 comments
Hello everyone!
I'm trying to use this synth in an arduino UNO and, even in all examples, the only output I have in the osciloscope is a saw wave! I'm loading examples using the suggested connection with the supposed resistors and capacitors.
Anyone knows what's the problem?
Did you try to listen to it, or just saw it? Is your setting ok? It loks like the charge/discharge of the capacitor, but with various decharging slopes.
Also, I can see that the frequency setting is 62,5kHz, so there's a chance you're looking to the PWM that generates the audio wave. What do you see when setting a frewuency around what you should hear? That's to say, something between around 100-10000Hz.
Triangle is just a PWM artifact. Try listening to the signal (looks to be
correctly modulated)

I haven't explained myself correctely. The output wave was supposed to be a sine wave, in this situation we are using example "modulation.ini". I'm measuring in the audio output node.
Yes :)
