MPLAB IDE
MPLAB PM3 USB Device Driver
First Time Installation

For Windows 2000 and XP

 

To use MPLAB PM3 with USB communications, the following steps MUST be taken in order to properly install the device drivers. 


 

Before You Begin

MPLAB PM3 should NOT be plugged into a USB port, powered, or have a device plugged into it at this time.

  • If you have already plugged MPLAB PM3 into the USB port and the "Found New Hardware Wizard" has popped up, click Cancel on that dialog, unplug the MPLAB PM3 and continue with these instructions.
  • If you have already plugged MPLAB PM3 into the USB port and used the  "Found New Hardware Wizard" to install drivers automatically, you have installed the wrong drivers. Follow the instructions specified in C:\Program Files\Microchip\MPLAB IDE\MPLAB PM3\Drivers\clnpm3.htm.

Software Preliminaries

Install the latest version of MPLAB IDE. You can get a free copy of this application from our website (http://www.microchip.com) or from your local Microchip sales office on CD-ROM.

During the-install, a dialog may pop up stating, "The software you are installing for this hardware: Microchip Development Tool has not passed Windows Logo testing..." In this case, Microchip Development Tool will be "Microchip MPLAB PM3 Firmware Client". Click "Continue Anyway".

If this happend, click the Continue Anyway button.

 

STEP 1

Connect  MPLAB PM3 to the PC with a USB cable. Then, connect the power supply and turn on the unit. Do not insert a device into any sockets modules on MPLAB PM3 at this time.

If you are using an external USB HUB, make sure it has a power supply and is powered or MPLAB PM3 will not work.

STEP 2 - Windows XP SP2

If you have service pack 2, the first time a new USB device is plugged into a Windows XP system, this dialog box will appear indicating that the system has found a new hardware device and asking you whether or not to search for update software. Select "No, not this time".  Click "Next" and continue with the steps below.

STEP 3

The first time a new USB device is plugged in, a small dialog box will appear indicating that the system has found a new hardware device. There also may be a dialog box that informs the user that a device data base is being built or updated.

After these dialogs appear, the Found New Hardware Wizard dialog box  is displayed. Select "Install the software automatically (Recommended)" and click "Next" to continue the installation.

Note: If you are running Windows 2000, you may not see this or the next dialog. Instead, the system will automatically install the software without asking you. This is OK. Proceed to Step 5.

STEP 4

During the install, a dialog will pop up stating, "The software you are installing for this hardware: Microchip Development Tool has not passed Windows Logo testing..." In this case, Microchip Development Tool will be "Microchip MPLAB PM3 Firmware Client". Click "Continue Anyway". (See Software Preliminaries for a picture of this dialog.)

The "Completing the Found New Hardware Wizard" will appear once the Microchip MPLAB PM3 Firmware Client has been installed. Click "Finish" to end the USB installation.

STEP 5
