MiniIDE
• In order to communicate with the Dragon 12 Plus, we need to
have/use
– Terminal program to send typed inputs to the board and see the
output from it.
– Assembler to assemble the assembly program.
– Text editor to edit assembly program
• The IDE is a integrated tool for all of above.
• Integrated Development Environment (IDE)
– Source code editor, assembler, and etc.
• MiniIDE is an IDE for HCS12 assembly programming
– You can download the software at
