CPUStick is a 1”x4” very low cost standalone USB embedded computer based on the Freescale MCF52252 ColdFire MCU and MC13201 ZigFlea Wireless Transceiver, similar in size and form to a USB “memory stick” and suitable for use in soldered or solderless-breadboard applications. StickOS BASIC is an entirely MCU-resident interactive programming environment, which includes an easy-to-use editor, transparent line-by-line compiler, interactive debugger, performance profiler, and flash filesystem, all controlled thru an interactive command-line user interface. A StickOS-capable MCU may be connected to a host computer via a variety of transports and may then be controlled by any terminal emulator program, with no additional software or hardware required on the host computer. Once program development is complete, the MCU may be configured to autorun its BASIC program autonomously.
