dsPICDEM™ 1.1 Plus Development Board User’s Guide
DS70099D-page 66
Oscillator selection parameters are shown in Table 5-2.
TABLE 5-2:
5.1.16
By placing J10 jumper in the MCLR1 position, the Reset switch connected to the
processor MCLR pin provides a hard Reset to the dsPIC DSC device. By placing J10
jumper in the MCLR2 position, the Reset switch is connected to the PIC18F242 LCD
controller.
The Reset switch circuit is shown in Figure A-2: “dsPICDEM™ 1.1 Plus Develop-
ment Board Schematic (Sheet 1 of 5)”.
5.1.17
A prototyping area and associated header are provided on the development board to
enable additional ICs and attachment boards to be added (see Figure
A-2: “dsPICDEM™ 1.1 Plus Development Board Schematic (Sheet 1 of 5)”).
5.1.18
A sample dsPIC DSC device programmed with the demonstration code is included in
the dsPICDEM™ 1.1 Plus Development Board Kit. The 80-pin TQFP is soldered to a
1.5” x 1.5” adaptor PCB, which is inserted onto the emulation header, J11 and J13-J15.
Handle the device carefully when inserting and extracting the adaptor board. The
orientation of the adaptor board is important. The Microchip logo and device part
numbering should be aligned to read from left to right before insertion of the adaptor
board. The pin 1 index marker of dsPIC30F device should align with the lower left
45° corner of the 80-pin QFP footprint (pin 1 of Emulation Header J14).
Pin-out information for the emulation header is shown in Figure A-2: “dsPICDEM™
1.1 Plus Development Board Schematic (Sheet 1 of 5)”.
