Introducing MiniIDE

MiniIDE is a tool for students and embedded software developers who write software in assembler for Motorola's 68HC11 and 68HC12 microcontroller.

MiniIDE is an integrated development environment running under Windows XP or higher. It was especially designed for Motorola's M68EVB912B32 evaluation board and replaces the assembler which comes along with the EVB package. However, it can be used for any evaluation board that has the 68HC11 or 68HC12 on it. MiniIDE incorporates an editor and a serial communication terminal. A command line cross‑assembler, which is seamlessly integrated in the IDE, is included.
