Connect the RS-232 cable from the PC to the UART connector (J2). 6. Reapply power to the DC IN connector (J4). The PWR ON LED should illuminate. 7. Load the sample application program for the dsPIC30F2011 (see Section 4.4 “Device Programming”). TABLE 4-1: dsPIC30F2011 CONFIGURATION SETTINGS Component Header Socket U1A1 No. Jumper Setting Pin Device Functions (see Figure 4-1) Jumper JP1 JP1 Jumper — 5 VDC jumper installed Jumper JP2 JP2 Jumper — 5 VDC jumper installed Selector Switch S2 GP 18 ON 11,12 PGC and PGD Selector Switch S3 OFF — Not used in this configuration Selector Switch S4 OFF — Not used in this configuration PGM U3 H11 Open — No jumper connections CAN Tx H2 Open — — CAN Rx H2 Open — — UART1 Tx* H3 Open — — UART1 Rx* H3 Open — — Alternate UART1 Tx * H4 GP ALL 8 EMUD1/SOSC1/T2CK/U1ATX/CN1/RC13 Alternate UART1 Rx * H4 GP ALL 9 EMUC1/SOSCO/T1CK/U1ARX/CN0/RC14 UART2 Tx* H5 Open — — UART2 Rx* H5 Open — — Temperature Sensor H10 GP ALL 5 AN3/CN5/RB3 Potentiometer H13 GP ALL 4 AN2/SS1/LVDIN/CN4/RB2 Switch S5 H6 Open — — Switch S6 H7 GP 18 10 EMUC2/OC1/IC1/INT1/RD0 LED D3 H12 GP D3 2 AN0/VREF+/CN2/RB0 LED D4 H12 GP D4 3 AN1/VREF-/CN3/RB1 LCD - SPI™ Clock* H1 GP 18 16 AN6/SCK1/INT0/OCFA/RB6 LCD - SPI Data* H1 GP18 11 PGD/EMUD/AN4/U1TX/SDO1/SCL/CN6/RB4 * On this device, multiplexing of various peripherals on the pins does not allow the simultaneous use of: – Switch S5 and LCD – Primary UART1 pins and LCD. Since only one DB-9 connector is provided for RS-232 communication, you can select either UART1 (primary or alternate pins) or UART2, but not both. |
