README
README.mdPico-scanline
Pico Scanline is a 15kHz test pattern generator for CRT monitors and arcade hardware (JAMMA), powered by a Raspberry Pi Pico (RP2040).
This project uses the PicoVGA library and generate 15kHz (240p) video signals for cathode-ray tubes, using the RP2040's PIO and DMA capabilities.
Features
- 15kHz Signal (240p): Native output optimized for arcade monitors and CRT TVs.
- Built-in Test Patterns:
- Geometry grids.
- Color bars.
- Purity and convergence patterns.
- THT testing
- PicoVGA Core: Utilization of PicoVGA for high-speed graphics rendering and precise timing.
- Open Source: Built using the official Raspberry Pi Pico SDK and PicoVGA.
Prerequisites
- Raspberry Pi Pico
- Custom PCB (Download Gerber files or Order on PCBWay)
- Pico SDK 2.2.0+.
- PicoVGA Library.
Compilation
To build it standalone:
mkdir build && cd build
cmake ..
makeThis produces picoscanline.uf2 in the bin/ folder.

Questions
How big is the Pico scanline PCB?
It measures 114.8 × 58.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pico scanline use?
24 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Pico scanline KiCad files?
From the philhp/Pico-scanline repository on GitHub, at the commit this page was made from: the board is hardware/picoscanline.kicad_pcb and its schematic hardware/picoscanline.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pico scanline design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
