Full open-source(GPLv3) platform for multiple applications, including programmer, debugger, logic tester, logic analyzer, simple oscilloscope and so on.



Versaloon is a full-opensource multi-functional platform based on generic USB_TO_XXX protocol, which can now support more than 10 kinds of interfaces including JTAG, SWD, SPI, IIC and so on. USB_TO_XXX is not only used to control these interfaces, but also it can play in one command a complex timing on multiple interfaces with some high-level functions(accurate time control, polling, nesting, compare/verify and so on). The coming VersaloonHandy platform expands HMI and storage functions, and is suitable for some interesting applications, including logic analyzer, simple oscilloscope and so on.
