I've also seen small computer boards used to flash LEDs and display "Hello World" on an LCD etc...!

My thought on them is: "Use a sledge hammer to crack a Walnut" :-)

A total waste of resources and time, because Python is so convoluted and bloated, and actually rather slow, and sitting on a computer running a Linux operating system, for what?.

I have some Positron8 code that will read 16-bit WAV audio files from an SD card formatted as FAT32, and play them via two 8-bit HPWM channels operating as a single 16-bit DAC using two resistors, where one resistor is approx 256 times larger than the other, and the audio is excellent with a decent amplifier chip and a good speaker. And all on a single, small, PIC18F device using its internal 64MHz oscillator!

Hi Less
Do you mind to share that Positron8 code that will read 16-bit WAV audio files from an SD card formatted as FAT32 with the circuit diagram, I found this fascinating.
Cheers

Hi Less,
I've been looking for a project  like this one for a while..!

Unfortunately, it is part of a, hopefully, future commercial product I am going to try to make and sell, so I cannot give the code.

The product is my unique "storypainter" audio light. However, I do not have a commercial mind, so it is taking a lot longer than it should to sort the commercial side out. The code and circuit are all done, as is the PC application to add the colour to an audio story, but I struggle with the commercial side, as to... How to advertise it. How to promote it. How to sell it, and at what price etc...
