This Library is to control all pins on a port as a PWM signal which is known as bit-banging. Bit-banging is when the microcontroller generates the signal and not external hardware. This can work but ...

Use the CCL peripheral of the ATmega4809 on the Arduino Nano Every board to create a WS2812B "NeoPixel" addressable RGB LED driver without bit-banging.

Besides the standard tools like Bus Pirate, GreatFET, FTDI modules, etc., are there any similar tools you like to use for bit banging and serial testing? Let us know in the comments below.
