When using the MPLAB ICD 2 as a programmer, the microcontroller will not run unless
you disconnect the MPLAB ICD 2 or release the MPLAB ICD 2 from Reset. Figure 3-1
shows the “Release From Reset” button.
FIGURE 3-1:
3.2.5
Check that a Fault has not occurred by checking that the FAULT LED is off. Verify the
Brushed DC motor is connected between DRIVE 1 and DRIVE 2. In order to measure
Back EMF, DRIVE 1 must float and DRIVE 2 must be grounded (i.e., the N-channel
MOSFET for Drive 2 is the only MOSFET turned on).
3.2.6
Only one microcontroller should be installed on the board at any given time.
3.2.7
The optical interrupter circuit is susceptible to interference from outside infrared light
sources (i.e., incandescent lights, sunlight, etc.). It may be necessary to block this
source or turn off the light source when using the optical interrupter.
3.2.8
If using the USART on the PIC16F690 or PIC16F917, note that the TX and RX pins are
already connected. Make sure there is no shunt present on JP2.
