Using the MCP215X/40 Developer’s Daughter Board
with the PICDEM? HPC Explorer Demo Board
D.1.2
PC Demos using HyperTerminal
When using a PC with HyperTerminal as the Primary Device interface, all three
PICDEM HPC Explorer Demo Board programs can be demonstrated. These are shown
in:
Note:
D.1.2.1
HyperTerminal should be disabled before establishing a connection
between the PC and the MCP215X/40 Developer ’s Daughter Board. Make
sure that any other programs (e.g., HotSync ? ) connected to the IR ports
are disabled.
DEMO #1 OPERATION - 250 BYTE TRANSFER MODE
In Demo #1, the System 2 unit will receive a character and then stream 250 bytes of
data (25 lines of 8 alphanumeric characters plus the return and line feed characters, for
a total of 10 characters per line).
The System #1 unit is connected to the PC, while the System #2 unit is not required to
be connected, though it still needs to be powered. The PICDEM HPC Explorer Demo
Board is used to determine the communication baud rate (115,200) 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 interface headers.
Jumpers JP3 and JP4 are used to select which demo program to run. Figure D-3 shows
the jumper configuration for Demo #1.
Table D-2 shows the steps for Demo #1.
