Using the MCP215X/40 Developer’s Daughter Board
with the PICDEM? HPC Explorer Demo Board
D.1.2.3
DEMO #3 OPERATION - DIRECT TO UART (DB-9) MODE
In Demo #3, the MCP215X/40 Developer ’s Daughter Board will communicate directly
to the PICDEM HPC Explorer Demo Board’s DB-9 connector (and then to the PC). The
PICDEM HPC Explorer Demo Board is used to determine the communication baud rate
(9600) via the JP2 and JP1 jumper states. Given this state, the PICmicro MCU can then
configure the MCP2150 UART baud rate. Power is supplied over the H1 and H2 inter-
face headers. Jumpers JP3 and JP4 are used to select which demonstration program
to run. Figure D-7 shows the jumper configuration for Demo #3. The jumpers that are
circled are the jumpers that change position.
Table D-4 shows the steps for Demo #3 operation.
