1.3.1. Design Notes

To demonstrate this design on the MDN-B2 Demo Board, follow these steps:

  1. Turn on the power to the demo board (using slide switch SW1).
  2. Download the design on to the MAX II device through the JTAG header JP5 on the demo board and a conventional programming cable (ByteBlaster™ II or USB-Blaster™). Keep SW4 on the demo board pressed while starting the programming process. After programming, turn off the power and remove the JTAG connector.
  3. Mount the DS2745 battery gauge module (supplied with the MDN-B2 demo board) on the header JP3 of the demo board. Make sure that the red mark on the connector meets pin #1 on JP3.
  4. Turn on the power to the MDN-B2 demo board.
  5. Observe that the red LED array on the demo board vary with changing voltages on the battery gauge module. This voltage can be varied by changing the preset on the battery gauge module.
