Note: For users who will use CodeWarrior IDE with serial monitor:
This manual is written for the board that is pre-installed with bootloader and D-Bug12
monitor. For some university students who need to work with CodeWarrior IDE, the board is
pre-installed with serial monitor and a factory test program. The software installation on the
page 13 is not needed. Once the serial monitor is installed, the board will not work with AsmIDE
or other terminal programs.
The left DIP switch of S7 has been set in the “up” position as a factory default setting for running
the test program. When the board is turned on, it will display the letter “U” on the 7-segment
LED before running the test program. If it displays the number “5” then the left DIP switch of S7
is set in the “low” position. You have to set it in the “up” position and then press the reset
button. The functions of the test program are described in the test16P3,asm in the
C:\MiniDragon_P3\CodeWarrior_examples. The letter “U” stands for running User program.
After running through the test program you have to reset the left DIP switch of S7 in the “low“
position for interfacing with Code Warrior IDE.
When the left DIP switch of S7 is reset in the “low“ position, then if you press the reset button,
the 7-segment LED should display the number “5” momentarily. On a 7-segment LED, the
number 5 and letter “S” are exactly the same. The number “5” means the letter “S” which
stands for serial monitor mode.
