Function Generator android APDE the signals generated with continuous mode or PRF /pulse mode slider simulate R1 in the schematic 15k to control PRF and PRP or interval as in real the 555/556 acts

Looks very nice and usefull!  
I used some weird online calculators or hand math back in the days…  
This looks much more comfortable to use.

Hi

The sketch generates realtime audio sine square sawtooth triangle with desired frequency in two modes … 555/ 556 not just simulation but given the function Generator realtime PRF/PRP

My next step making the android sound card as TX /RX or as transceiver at the same time

APDE has the same issue as it uses processing for android 😅
