Hi Mike.

I'm using the PIC16f877 with the microchip ICD2. I've reached the point in this project where the debugging is over and the microcontroller is now required to run independently of the PC as part of a stand-alone device.

I've tried to program the device in program mode in the MPLab IDE but the device doesn't work after it's switched off and on again. What needs to be done to get the PIC to operate independently? Is it some kind of jumper on the MCLR pin?

Thanks very much,

Richard

Hi,

If your project works in debugger mode while connected to ICD2 and doesn't when in standlone mode, it probably means you did not set properly the configurations bits...This shoule be done in your source file.

In case you have an external reset, then select this choice. If not program the configuration bit so that it uses the internally generated reset.

I would like to use a resistive touch screen with a PIC controller. I don't have experience with touch screens.

How can I interface the touch screen with PIC? Should I use a touch controller?

What communication interface is mostly used for touch controllers (SPI,I2C,UART)?

How can I program the GUI? Is it done on the PIC or touch controller?

Is there any software form microchip for programming GUI?

Thanks very much

Alen

Hi,

It depends what you want to do.

For resistive touchscreen you can either use the PIC onboard A/D converter or an external Touchscreen controller.

If you use the PIC onboard ADC significant computation will be needed to filter / shape the signals from the resistive inputs. This should be preferred if you use a more powerful PIC like 16 bits one or possibly also with PIC18. Of course the larger the screen & resolution the more computation will be needed.

On the other hand if you use a touchscreen controller like the AR1000 family from Microchip, you get a clean input as it takes care from all the filtering / sampling / averaging. No CPU bandwith is needed ;=)

If you want to get started fast, Microchip released a Touchscreen starterkit with PC GUI :

All details on the AR1000 familiy here :

Hi

Is the AR1000 touch controller used only for the touch interface or also for GUI? Or should I use another controller for GUI? How is the programming done for GUI.

Thank you

Hi

I got an explorer 16 board, tried to build it but I couldn't. The error is

Make: The target "C:\tutorial\adc.o" is out of date.

Executing: "C:\Program Files\Microchip\MPLAB C30\bin\pic30-as.exe" -mcpu=24FJ128GA010 -x c -c   "adc.c" -o"adc.o" -D__DEBUG -D__MPLAB_DEBUGGER_ICD2=1 -g

C:\Program Files\Microchip\MPLAB C30\bin\bin/pic30-coff-as.exe: unrecognized option `-mcpu=24FJ128GA010'

Halting build on first failure as requested.

The user guide I got is not matching with MPLAB. I have bought Explorer 16 100 pin and I would like to use PIC24FJ128GA010. The code example and other demo files provided in the CD are for PIC24FJ64GA004.

Is there any new version of explorer 16 user guide available or demo files for PIC24FJ128GA010. Could you please advice me how to get the build succesful.

Thank you

Alen

Hi,

There are 2 different EXPLORER16 versions :

DM240001DM240001 explorer16 board shipped with 2 different processor modules(PIC24FJ128GA010 dsPIC33FJ256GP710) both 100 pins

DM240002.DM240002. : explorer16 shipped with the PIC24FJ64GA004

Bonjour,

Nous voulons réaliser un projet avec des  produits Microchip.  Nous souhaitons chargé mécaniquement la machine qui  est controlé actuellement par un onduleur.  Nous avons en main les  produits suivants:

DISPIC30f  MA300015MA300015

MOTOR 3 PHASE H VOLTAGE

CABLE BREADBOARD MPLAB ICD2  AC162069AC162069

MPLAB ICD HEADER 162051

MODULE SOCKET FOR ICD2 DIP  AC162049AC162049

Merci de votre aide.

Hi there , I'll try and answer your question based upon the information you have provided .

To develop a 3 phase Induction motor application you should look at the following 3 options .

dsPIC30F development

ICD2 or ICD3

High Voltage Power Module  DM300021DM300021

Microchip Motor Control Dev Board  DM300020DM300020

or

dsPIC33F development

ICD2 or ICD3

Explorer 16 board  DM240001DM240001

Pictail Motor Control Board ( includes PIM for Explorer 16 board ) AC164128AC164128

High Voltage Power Module  DM300021DM300021

or

dsPIC33F development

ICD2 or ICD3

MCHV Development Board DM330023.DM330023.

your development route will depend upon the type / size / degree of control you require - it may be that a PIC18F could offer the control you need - checkout the following page for more info - regards , Mike

Bonjour,

Je vois que vous avez déjà fait plusieurs choix mais je n'ai pas lu votre besoin.

Connaissez-vous les dsPIC33 (famille plus récente que les dsPIC30) ?

Nous avons une gamme de produits dédiés dsPIC aux onduleurs dans la famille appelée SMPS dont vous trouverez les informations ici : http://www.microchip.com/SMPS

Nous possédons aussi toute une famille de dsPIC dédiés au contrôle moteur : http://www.microchip.com/MOTOR

Il serait peut-être plus simple de nous expliquer ce que vous souhaitez faire de façon à ce que nous vous proposions les produits et outils les plus adéquats.

Je vous déconseille l'achat d'un ICD2 qui a été remplacé par l'ICD3 plus performant et moins cher

Pour nos microcontroleurs 16 bits je vous recommande d'ailleurs le Real-Ice plutôt que l'ICD3 car il apporte des possibilités de DEBUG beaucoup plus importantes.

De plus, il est possible de participer aux formations Microchip qui ont lieu toute l'année dans le centre de formation : http://www.microchip.com/RTC

     Une formation 16 bits pour PIC24 et dsPIC est prévue au mois de juin. J'attache le catalogue de nos formations ainsi que le descriptif de notre cursus 16 bits.
