Preamble
My mate Rodders sent me this to investigate.
Following on from A tiny one and Using an ATtiny development board, I figured that it was time to get the DigiStump/DigiSpark ATtiny85 board (that I had ordered over two months ago) to work, seeing as I had failed to get the ATtiny85 and the development board to work previously.
This time around it was a lot easier…
Code to make an ATtiny15 output a 2 MHz clock signal.
As the Atmel datasheet recommends frequencies no higher than 1.75 MHz, then you will need to use an ATtiny25/45/85 for frequencies greater than this.
Following on from the VGM player using the SD76496 mentioned in Chiptunes, I thought I’d look into the NodeMCU…
