A description of the demos, including step-by-step instructions are shown in this
section.
2.3.1
In Demo #1, the MCP2120/22 Developer’s Board #2 will take any data that is received
from the IR interface and send it directly out the UART interface to the PC’s serial port.
Any data that is received from the UART interface will be directly sent out the IR
interface.
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 2-1 shows the system setup for this test, while Figure 2-2 shows the jumper
configuration for both of the MCP2120/22 Developer’s Boards. Lastly, Table 2-4 shows
the steps for Demo #1 operation.
