Demo #2 Operation
In Demo #2, the System 2 unit will echo any alpha character received, changing the
case of the character (lowercase to uppercase/uppercase to lowercase). The System
1 unit is connected to the PC, while the System 2 unit is not connected, though it still
needs to be powered. The PICDEM™ HPC Explorer Demo Board is used to determine
the communication baud rate (9600) via the JP3, JP2 and JP1 jumper states. Given
this state, the PICmicro
®
MCU can then supply the 16XCLK frequency to the
MCP2122. Power is supplied over the J1 and J2 interface headers. Jumper JP4 is used
to select which demo program to run. Figure D-3 shows the jumper configuration for
Demo #2.
Table D-3 shows the steps for Demo #2.
