Installation of the Expansion Board

  • When mouting Expansion Board on e-Bug, double check that ALL of the pins are aligned correctly before providing power to the board.
  • The function in the firmware (FW) which sets up the Expansion Header is here:
    http://code.google.com/p/monash-wsrnlab/source/browse/trunk/ebug/ebug/src/ebug.c#3699
    At FW startup, it is called here:
    http://code.google.com/p/monash-wsrnlab/source/browse/trunk/ebug/ebug/src/ebug.c#1179
    So, you need to change that rotary switch to 1 when Expansion Board is connected to an eBug.
  • When expansion board is connected to the eBug, you don't want any header jumpers on P4 (Board Power Enable) or P6 (Enable onboard 3.3V reg enable) - this is because you want the eBug to turn on the power to the board via the FW, here:
    http://code.google.com/p/monash-wsrnlab/source/browse/trunk/ebug/ebug/src/ebug.c#3730
    and because the eBug also supplies the required 3.3V, respectively.
  • Ensure that:
    • resistor (R10) is not installed
    • resistor (R4) is installed
    • Following jumpers and resistors should not be installed (marked with blue on the diagrams below)
