Run Code with Serial Debug
This debug method gives feedback from a running program via the FX3 UART port. Since modern
PC’s do not include serial ports, you will need a serial-to-USB converter such as the Keyspan (Tripp
Lite) USA-19-HS (
Figure 2-19
). If you have a serial port, you can connect a DB-9 cable instead.
Figure 2-19. Connect a Serial-to-USB Adapter to the DB-9 Connector
To see the debug messages you need a terminal program such as the free
Tera Term
used in the
following steps.
1. Plug the serial adapter USB cable into the PC, and then start Tera Term. A serial device must be
plugged into the PC before starting Tera Term to be recognized.
2. Select the
Serial
option and the adapter COM port as shown in
Figure 2-20
.
