9.13 PN7462AU_ex_phExVCom
This example application features TypeA card detection, RF filed control and
communication with the PC host over USB CDC interface (VCOM).
9.13.1 Demo setup
Board is connected to the PC host via USB interface. USB micro socket X3 needs to be
connected to the PC’s USB port. The proper USB host interface configuration on the
board is depicted in 3.2.1.1 (not needed for PNEV7462C). Application outputs debug
traces to and receives commands from the terminal emulation application running on the
PC host. Serial port parameters are 9600/8/1/N/1.
9.13.2 Command sets
Commands are entered by the terminal emulation program. Each command is one-
character long.
a) T command (character T), example application enters Type A detection mode and
the terminal output is as follows:
Poll command received
Entering TypeA Polling mode..
Type A Polling
Type A Polling
Card UID=0424566AF13B80
Card UID=0424566AF13B80
Card UID=0424566AF13B80
Type A Polling
Type A Polling
LED8-10 lit in circular pattern.
b) O command (character O), example application turns RF filed permanently ON, the
corresponding output on the terminal console is:
RF ON command received
LED9 (Green) and LED10 (Blue) lit.
c) F command (character F), example application turns RF filed permanently OFF,
output on the terminal console is:
RF OFF command received
LED7 (Red) and LED8 (Yellow) lit.
9.14 PN7462AU_ex_phExDoorAccess
The example application demonstrates card detection, card authentication and HSU
interface communication with the PC host. The application is running a NFC polling loop
and goes to standby mode after each polling loop in case no CL card is detected by the
RF field of the reader. The polling loop is implemented for Type A, B, F, ISO15693 and
ISO 1800-P3M3. The application prints out the detected type of the card and UID if
