Hardware Details

SOCKETS

40 Pin ZIF socket is provided for the processor. Microcontroller can be removed from the board easily. This socket is intended to use our development board as programmer to program other IC’s. 10 pin FRC box type connectors: This will be found in each section of DSPIC 30F development board. A 10 pin FRC cable is used to make connection with the main board section. Any 8 bit port of microcontroller can be used for interconnection. Ports having less than 8 bits are used as control signals for various sections.





Pins 1-8 are Data Pins. Pin 9 is VDD and the Pin 10 is GND. All 10 Pin FRC connectors will follow the same rule.

JUMPER SETTINGS





CONFIG SWITCH

SW1: 10 way Multifunctional switch





ANi/P SWITCH

SW24: 4 way analog channel selection switch





 

POWER SUPPLY

The external power can be AC or DC, with a voltage (15V, 1A output). The DSPIC board produces +5V using an LM7805 voltage regulator, which provides supply to the peripherals. Power supply is controlled through slide switch SW2.





Installation Notes

Installing MPLAB IDE

Open up the user CD comes with DSPIC Microcontroller Board, Navigate to MPLAB IDE Folder

Double Click Setup.exe and Click → Next





Click >>I accept the terms of the license agreement and Click → Next





Select >> Complete check box and Click → Next





Click >> Next





Click >> I accept the terms of the license agreement for both Application Maestro as well as MPLAB c32 windows and Click → Next, Next







Click >> Next to Start Copying Files





Now the MPLAB IDE setup will Progress



After finishing installation MPLAB IDE, it will prompt for HI-TECH C Installation. Click → No

Click >> Finish to InstallShield Wizard Complete





Just Close the MPLAB IDE Document Support





Installing MPLAB C30 compiler

Purchase this compiler from microchip or download their 60 days student version. Install the compiler as per their manual. Then follow the next step.

Creating a Project on MPLAB IDE

Double Click the MPLAB IDE v8.xx from desktop





To create a new project, Click → Project and Project Wizard.





At the first page of Project Wizard, Click >> Next.





Step ONE: Next, you will need to select the device for your project. For this demonstration I will use DSPIC16F877A as the device.





Afterselecting the device, click >> Next





Step TWO: Select the Compiler for your Project.





Click the Active Toolsuite drop box and select MPLAB C30 ToolSuite.





 

There should not be any red “X” mark (For those with the red “X”, please reinstall the MPLAB C30). Click Next to continue.

Example: See the “Red X” mark that appears before CCS C compilers





Step Three: Select the directory to store your project and your project name.

i. Click on Browse to open a browser where you choose the directory and the project name.

ii. It is advised that you use a new folder for a new project, and all the coding file (c file, h file, asm file) should be stored under the same folder.





Now enter the Project Name and Click >> Save





Click >> Next to the following window





Step four, If you have an existing file Select that file and Click Add>>, Otherwise Just Skip this step by clicking Next.





You have successfully created the project. Click Finish to continue.





The project that you create will be open after you successfully created it, and this is what you will see at the IDE, a Project window and an Output window.

If you don’t have these windows on your IDE, you can always enable it back by clicking View >> Project and View >> Output.





Click on the icon (New File) to create a new file.





Enter All your codes or Enter spacebar once and Click File >> Save.





Enter the file name with “.c” extension. Check the box “Add File To Project”. Click Save to save it in project directory.





IF you forget to Check the box “Add File To Project”, You can add your source file by right clicking at the Source File and click Add Files.





Select the file that is being saved. Click Open





Now the code file “.c” is added to your project. You can see that it is shown under the Source Files at the Project window.





Now Right Click On Linker Script and Click Add Files…





Navigate to “C:\Program Files\Microchip\MPLAB C30\support\dsPIC30F\gld” and select your IC’s linker script. Click Open





Now everything has been done. Now write your code or modify the existing code….





Click build All to compile the project and correct the error, do rebuild etc…





Configuring Programmer for DSPIC Development Board

First attach the DSPIC Microcontroller Development Board with PC via USB cable.

Connect the 9V AC/DC Adapter with Development Board or Just use USB power.

Turn ON the Power Switch (either USB side or EXT side).

Wait until the PICkit2 Finishes Driver Installation*. If the driver not detected just try to reconnect or RESTART your system, then try again.



After Finishing the Hardware driver installation. Open MPLAB IDE. Select Programmer >> Select Programmer >> PICkit2





 

Note*: Driver installation is required for this board when it is connected to the PC for the very first time.

If the Kit is properly connected, you can see the PICkit2 Icon set on the Toolbar (Yellow Set) and the PICkit2 Ready Message. Very First icon is used for “Programming the device”.





Finally open our Example Programs, Burn it to the controller, do the hardware connection as per Chapter 4 and See the result.

POSSIBLE ERRORS

Error 1: MPLAB may throw "Write Failure-Get lost Error". If it does, follow the instructions below,

  • a) Unplug the Power supply from target board
  • b) Close MPLAB
  • c) Plug the AC/DC adapter
  • d) Reopen MPLAB

Error 2: MPLAB may throw "target not found" error or “Unspecified device error”. If it does, follow the instructions below

  • a) Ensure whether the DSPIC microcontroller placed properly in ZIF jacket.
  • b) In Configure-->Select device, ensure DSPIC16F877A (or any) is selected.

Error 3: MPLAB may throw "Verified Failed" error, due to the following

  • a) Hex File may be old, so compile the project once and try Programming.
  • b) Faulty microcontroller device, Replace it with new one.

Note *: If the error still retains check your windows firewall or antivirus software to allow this MPLAB and DsPICkit2 programmer.
