Based on the 5 yuan Raspberry Pi RP2040, 24-channel 100Msps logic analyzer open source project

Foreign netizen gusmanb has made it open source, making it easy for everyone to make their own. The hardware is independently completed by the Raspberry Pi microcontroller RP2040, which costs 5 yuan a piece. Just close a trigger design baseplate designed by KiCAD. The software uses the VSCode + GCC + Cmake method to create projects. It doesn't matter if you don't know how. The firmware upgrade uses the U disk drag-and-drop method that comes with the Raspberry Pi chip. If you want to add other functions, just compile the project with magic modification.

As for the host computer, .net6 is used. The advantage is that it supports cross-platform. At present, the author only downloads the Windows platform, and will launch Linux and MacOS platforms later. In the early design, the author used some open source analyzer software for testing, but the author didn't like it very much, so he designed a new host computer himself, and the results were pretty good.
