COMMON PROBLEMS
This chapter provides information for troubleshooting problems encountered while
using the dsPICDEM MCSM Development Board.
1. Problem: USB connection in DMCI fail (amber and green LEDs are ON)
FIGURE 4-1:
2. Problem: Switching noise
This condition is accompanied by the following error message:
Solution:
a) Disconnect the USB cable. When disconnected, the green LED turns OFF.
b) Reconnect the USB cable. When reconnected, the amber LED turns OFF,
While using a stepper motor, inductances are being switched on and off
frequently. Switching noise is present and can be seen with an oscilloscope.
Solution: To properly measure a signal, connect a probe to the desired signal
and one to ground and perform a division. The signal that results is what the
dsPIC DSC sees.
