How to setup the Miroslav Musil's HC12 board
The following section is a "How to" document dealing with HC12 board, developed at the Department of Control Engineering at Czech Technical University in Prague. The work is based on diploma thesis [1] and [2].
How to setup the board
- Disconnect the board from power supply
- Short JP1 and JP2 to 1-2 (Expanded Wide Mode)
- Disconnect JP6 (no auto run)
- Connect I/O module to CON1
- Connect RS232 bridge
- Canon connector to COM1:
- black connector to board connector CON4
- Connect the CAN interface to CAN bus
- Connect board to 12VDC power supply
How to download code from CodeWarrior to HC12
- Setup Codewarior
- Code can be simulated (see Help and included examples)
- Open Musil's VLoader application
- Open generated *.sx file
- Select correct serial port (eg. COM1 or COM2)
- Test HC12 connection (Test button)
- Download file to HC12
- Run application (Run button)
How to run HC12 application stand alone
