Novice pico time w/ Jojess

• I decided to make a music visualizer for my C64's PCM5102 DAC using a NeoPixel Featherwing and a Raspberry Pico. It was easy! ^///^

• Using blaz-r's extended ws2812b lib, which builds on benevpi's work.

• Please let me know what I'm doing wrong. It does work tho. <w<

Hardware list

• Raspberry Pico H
• PCM5102A
• NeoPixel FeatherWing
• 2-3 x 360/400 pin breadboards
• 220 ohm resistor [maybe a good idea?]
• 10k ohm resistor [is this right?] r* 220 ohm resistor
• 6-7 wires ;p

PicoH 2 NeoPixel - Cool Scripts

• pixldac.py - the purpose of this project. audio <=> pico <=> neopixel, cute rainbow marquee equalizer :3

PicoH 2 NeoPixel - Pinout

• pico H 1/GP0 => 220 ohm => neopixel_featherwing {DIN}
  • can I use a diode or something here, to minimize any impact it might have on the audio line? Is the resistor sufficent?
• pico H 40/VBUS/5v => neopixel_featherwing {VUSB}
• pico H 23/GND <=> neopixel_featherwing {GND/dataGRNRef}

PicoH 2 DAC - Pinin

• pico H 33/GND/AGND <============> PCM5102A DAC {GND}
• pico H 34/ADC2/GP28 <= 10k ohm <= PCM5102A DAC {R}

PicoH 2 NeoPixel - Toy Scripts

• transflag.py - trans flag marquee
• rainbow.py - raainbow flag marquee
• jojessowo.py - silly dots toy script
• rainbowsin.py - heartbeat over rainbow marquee
• pintestanalog2digital.py - read analog audio for an "oscilloscope", print val to STDOUT

Pico H File System

• mpremote fs
  • mpremote fs ls
  • mpremote fs rm :remotefile
  • mpremote cp localfile :remotefile
