menuconfig'. The UART pin selections would need to be changed by editing
configs/pc32mz-starterkit/include/board.h.
If using a AC320006 by itself, JP7 pin 2 and JP8 pin 2 is where you would
connect a 3.3 Volt ttl serial interface.
For a configuration using UART1 connect:
TX to AC320006-JP7 pin 2 which is PIC32MZ pin 106 (RPC14) used as U1RX
RX to AC320006-JP8 pin 2 which is PIC32MZ pin 31 (RPB3)) used as U1TX
For a configuration using For UART3 connect:
TX to AC320006-JP8 pin 2 which is PIC32MZ pin 31 (RPB3)) used as U3RX
RX to AC320006-JP7 pin 2 which is PIC32MZ pin 106 (RPC14) used as U3TX
If using a AC320006 plugged into a DM320002 then regardless of which UART,
UART1 or UART3 is configured in software, the jumpers on the AC320006 are
the same, just the signal directions and UART changes.
UART1 UART3
AC320006-JP7 connect pin 2 to pin 3. U1RX U3TX
AC320006-JP8 connect pin 2 to pin 3. U1TX U3RX
For the default configuration using UART1 the PIC32MZ pin 106 (RPC14)
will be configured as U1RX and is tied to the AC320006's JP7 Pin 2.
With the jupmpers as listed above, once the AC320006 is plugged into
the DM320002, the PIC32MZ U1RX will be connected to the DM320002's
J11 pin 43. The DM320002's J11 pin 43 should then be connnected to
the TX of a 3.3 volt ttl serial converter such as a FTDI TTL232RG.
For the FTDI TTL232RG TX is the oranage wire.
Likewise the PIC32MZ pin 31 (RPB3) will be configured as U1TX and
is tied to the AC320006's JP8 Pin 2. With the jupmpers as listed above,
once the AC320006 is plugged into the DM320002, the PIC32MZ' U1TX will
be connected to the DM320002's J11 pin 41. The DM320002's J11 pin 41
should then be connnected to the RX signal of a 3.3 volt ttl serial
converter. For the FTDI TTL232RG RX is the yellow wire.
For the alternate configuration using UART3 the PIC32MZ pin 106 (RPC14)
will be configured as U3TX and is tied to the AC320006's JP7 Pin 2.
With the jupmpers as listed above, once the AC320006 is plugged into
the DM320002, the PIC32MZ U3TX will be connected to the DM320002's
J11 pin 43. The DM320002's J11 pin 43 should then be connnected to
the RX of a 3.3 volt ttl serial converter such as a FTDI TTL232RG.
For the FTDI TTL232RG TX is the yellow wire.
Likewise the PIC32MZ pin 31 (RPB3) will be configured as U3RX and
is tied to the AC320006's JP8 Pin 2. With the jupmpers as listed above,
once the AC320006 is plugged into the DM320002, the PIC32MZ' U3RX will
be connected to the DM320002's J11 pin 41. The DM320002's J11 pin 41
should then be connnected to the TX signal of a 3.3 volt ttl serial
converter. For the FTDI TTL232RG RX is the orange wire.
