In Demo #4, the MCP2120/22 Developer’s Board #2 will take any data that is received
from the IR interface and send it out the UART interface (after passing through the PIC)
to the PC’s serial port. Any data that is received from the UART interface will be sent
out the IR interface (after passing through the PIC).
This shows the MCP2120/22 encoding and decoding data between the IR port and the
Host UART port. In this configuration the MCP2120/22 Developer’s Board can be used
as a IR to UART dongle.
Figure 2-7 shows the system setup for this test, while Figure 2-8 shows the jumper
configuration for the MCP2120/22 Developer’s Board. Lastly, Table 2-7 shows the
steps for Demo #4 operation.
