Memory Map Hardware Descriptions • LEDs • DIP switch and pushbuttons* • 7-segment LED * • Keypad • LCD display • Dual RS232 communication ports – DB9 female connectors D-Bug12 A Debug Monitor for the MC68HC912B32 Microcontroller • Basically D-Bug12 is a software program that interprets commands that a user types in. • You can interact with the microcontroller through D-Bug12 command. – Download your program – See/manipulate contents of memory and registers D-Bug12 Command Set Frequently used ones • • • • • • • • • • • BF - Block Fill user memory with data. BR - Set/Display user breakpoints. G - Go. Begin execution of user program. LOAD - Load user program in S-Record format. MD - Memory Display. Display memory contents in hex bytes/ASCII format. MM - Memory Modify. Interactively examine/change memory contents. NOBR - Remove one/all user breakpoints. RD - Register Display. Display the CPU register contents. RM - Register Modify. Interactively examine/change CPU register contents. T - Trace. Execute an instruction, disassemble it, and display the CPU registers. <RegisterName> <RegisterValue> - Set CPU <RegisterName> to <RegisterValue> 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 http://www.mgtek.com/miniide/ MiniIDE Source code editor Output of assembler Terminal window Demo Questions? Wrap-up What we’ve learned • Dragon12-Plus Development Board • DBUG12 commands • MiniIDE What to Come • Lab sessions start next Tuesday at AB-2817
