dtctr - Pocket sized 15Khz hsync generator.
Posted: Sat Dec 15, 2018 12:16 pm
The dtctr is a pocket device for use for testing if a monitor is 15KHz capable, a must if to be used with Atari ST and Amiga amongst other computers. It's powered by a 3V CR2032 battery and by the press of the power button it generates a test image within 6 seconds as of now since the firmware is really slow.
The firmware is based (slightly tweaked) on Nick Gammons work.
The hardware is basically an Arduino pro mini running at 16MHz, and can be programmed using the ISP header on the board.
