program?
Answer
Verify that the application circuit is not drawing more than 25 mA from the PICkit 2.
Microsoft Windows Driver
Question
After plugging the PICkit 2 unit into the USB port, Windows 98 SE asks for a driver.
Where is the driver?
Answer
The PICkit 2 uses the drivers included with Windows 98 SE. When Windows 98 SE
prompts for a driver, select “Search for the best driver for your device.” Then select the
checkbox next to “Microsoft Windows Update” and click Next. Windows OS will
automatically install the appropriate driver. Do not use Microchip’s MPLAB ICD 2 USB
device driver.
