SweCRTTester
RP2350B test-pattern generator for old CRTs: VGA, composite, S-video, and CGA.
Pictures are KiCad 3D renders of revision 0.99. A photo of a built board can replace them later.
SweCRTTester is an RP2350B board that streams test images for aligning old CRT monitors. Horizontal rate, vertical rate, and pixel clock are programmable.
- VGA: RGB 333 plus horizontal and vertical sync
- Composite and S-video through an AD724, sharing those same video pins
- CGA: RGB, intensity, and sync on their own pins
The pictures here are board renders from KiCad (rev 0.99). KiCad sources and RP2350 firmware are in git.
