Re: Modular uBitx - "Ex: Harmonics"

We ended up using the Teensy 3.6. 1Mb of flash, 256K of SRAM, 4K EEPROM, 62 I/O pins, I2C, RTC, 25 analog pins with 13-bit resolution and 2 analog output pins with 12-bit resolution (Mega has 10-bit). True, the blue pill cost less, but the libraries for the Teensy include most of the Arduino plus many others (FFT and audio). While this screen doesn't show everything:
we're using less than 20% of its memory resources. The companion audio board allows us to do some pretty cool stuff, like an 8-band equalizer (plot is on the left):
It's not cheap ($30), but is sure brings a lot to the table.

Blue Pill looks to be a winner too me, I have 2 laying about actually. VERY cheap, 2x the nano memory. and 32bit.
Should fit the bill perfectly, extra IO too. (26)
Just got to get the Code running on it, Jack?
