INTRODUCTION
HIGHLIGHTS
COMMON PROBLEMS
This chapter describes common problems when using the PICDEM Touch Sense 1
Development Board and their solutions.
Highlights covered in this chapter:
3.3.1
Question:
I am receiving the error message, “PICkit™ Serial Analyzer could not be found” in the
Transactions window, but the PICkit™ Serial Analyzer is plugged in. What is wrong?
Answer:
Open the Windows
System, selecting the Hardware tab and clicking on Device Manager button. Check if
there is an error displayed under Human Interface Devices as shown in Figure 13-1.
If an error is displayed, try unplugging and then re-plugging the USB cable until the
error goes away (this may take 3 or 4 tries).
If the error persists, try another USB port or hub. Try plugging the PICkit™ Serial
Analyzer into another computer to verify that the USB port is working.
3.3.2
Question:
I received the error message “USB Hub Current Limit Exceeded” from the Windows
operating system. What is wrong?
Answer:
The USB port current limit is set to 100 mA. If the target device plus PICkit™ Serial
Analyzer exceeds this current limit, the USB port will shut down. Check for shorts. The
target device can be externally powered if more power is needed.
3.3.3
Question:
After plugging the PICkit™ Serial Analyzer into the USB port, Windows
for a driver. Where is the driver?
