NTSC composite video test programs for Raspberry Pi Pico

I've implemented some test programs for Raspberry Pi Pico to generate NTSC composite video output.

Connection from Raspberry Pi Pico to RCA pin jack

GPIO14(pin19) -> 330ohm resister -> RCA+

GPIO15(pin20) -> 1kohm resister -> RCA+

GND(pin23) -> RCA-

Mini game pad with tact switches

Demo programs

• test_ntsc.c: Basic test for NTSC signal generation.

• test_ntsc_lifegame.c: Life game with NTSC video output.

• test_ntsc_shot.c: Tiny game named "FLYING METEOR!!".

• test_ntsc_shot2.c: Tiny game named "FLYING METEOR 2!!".

• test_ntsc_wall.c: Tiny game named "DROPPING MONSTERS".

All programs need font8x8_basic.h to draw ASCII fonts and some characters and are compiled with release option(speed optimization).

To compile a project

To copile a project, you need

• CMakeLists.txt,
• pico_sdk_import.cmake,

other than source and header files.

CMakeLists.txt

In CMakeLists.txt, you need to edit 'test_ntsc' as proper name to compile project.
