Use debug calls in your spin program to output debug messages to a TV/LCD composite video. Supports chr/out/tx, str, hex, dec, bin, clear, home, gotoxy, cr. Screen size 40x25, 60x25, 64x25 (80*25 with overclocking), NTSC or PAL, B&W, Text only.
Can also be used as a B&W TV Text terminal in your program, and can be in addition to any other output device(s) connected including TV and/or VGA.
Simple interface uses a single prop pin and 100R-1K1 (270R preferred) series resistor.
Font and a simple terminal program also reside within the cog. The screen buffer overlays the hub code after it is loaded into the cog, so it is a small footprint.
Now also includes optional 1-pin Keyboard Driver which uses 3 resistors.
v1.25 allows user selection of columns and rows.
v1.20 adds automatic parameters and faster terminal mode.
