4.2.3
An RS-232 level shifter (U3) has been provided with all necessary hardware to support
RS-232 connection with hardware flow control through the DB9 connector. The port is
configured as a DCE device, and can be connected to a PC using a straight-through
cable.
The PIC24/dsPIC33F RX and TX pins are tied to the RX and TX lines of U3. The
PIC24/dsPIC33F RTS and CTS pins are tied to the RX2 (DIN2) and TX2 (DOUT2) lines
of the MAX3232 for hardware flow control.
4.2.4
An analog output thermal sensor (Microchip TC1074A, U4) is connected to one of the
controller’s A/D channels.
4.2.5
The Explorer 16 board includes a PIC18LF4550 USB microcontroller, which provides
both USB connectivity and support for protocol translation. The PIC18LF4550 is
hard-wired to the PIC24/dsPIC33F devices to provide three types of connectivity:
• SPI™ of PIC18LF4550 to SPI1 of PIC24/dsPIC33F
• I/O pins of PIC18LF4550 to ICSP™ pins of PIC24/dsPIC33F
• I/O pins of PIC18LF4550 to JTAG pins of PIC24/dsPIC33F
The type of connectivity depends on the firmware installed on the PIC18LF4550. At the
time of initial release, the PIC18LF4550 is loaded with USB bootloader firmware, which
permits easy upgrades of connectivity firmware over the USB. Installing this firmware
is described in Appendix B. “Updating the USB Connectivity Firmware”.
PIC24 and dsPIC33F devices both have some 5V tolerant input pins. If a 5V tolerant
input is connected to the PIC18LF4550, protection diodes on the PIC18LF4550
device’s port pins will limit inputs to V
16-bit devices are 5V tolerant, refer to the appropriate device data sheet.
4.2.6
An MPLAB ICD 2 module can be connected by way of the modular connector (JP1) for
low-cost debugging. The ICD connector utilizes port pins, RB6 and RB7 of the
microcontroller, for in-circuit debugging.
Jumper J7 decides the terminus of the ICD 2 connector. If the jumper is set to the
“PIC24” side, JP1 communicates directly with RB6/RB7 of the PIM or on-board device
(determined by S2). If the jumper is set to the “F4450” side, JP1 communicates with the
on-board PIC18LF4550 USB device.
4.2.7
The Explorer 16 board includes an alphanumeric LCD display with two lines of 16 char-
acters each. The display is driven with three control lines (RD4, RD5 and RD15) and
eight data lines (RE7:RE0). On PIC24 devices, the LCD is driven by the PMP module,
not the I/O port.
The Explorer 16 board has multiple LCD footprints and support options, although only
one footprint is ever populated at one time. The Lumex LCM-SO1062 (populated at
LCD4) is a 5V LCD with TTL input, and is used in the initial version of the Explorer 16
board. The Tianma TM162JCAWG1 (populated at LCD1) is a 3V LCD; it is anticipated
to be used in future versions of the board.
An alternate configuration option allows the use of RD3:RD0 as four of the data lines,
instead of RE7:RE4. To do this, the user must cut the trace jumpers at R60/62/64/66
and create solder bridges from the pads for R61/63/65/67 (see Figure 4-1).
