could not get the output in Proteus simulation using DSPIC33FJ32GP204

Shanmuga.sndrmv · Dec 29, 2017

Dear Friends,

I am new to dsPIC33F ICs and trying to workout with Proteus simulation, in this I use dsPIC33FJ32GP204 ICs, I am trying to Blink LED using Proteus simulation, but it is not working. I have used PMD1 (Peripheral module disable register) for Digital port Access.

Hi,

Maybe your code is wrong --> show your code
Maybe your schematic is wrong --> shiw your schematic

Code not running in Proteus Simulaion, I am new to dsPIC

Re: dsPIC33F Code and Attached Schematic

Even if it will work, resistance value should be reduced 10000 times. But cleaver way is to use digital primitives, not analog once.

FvM · Dec 29, 2017

There are two problems in your code.

Your wait loop is infinite.

Code:

for(i=0;i<=65535;i++);

Try i<65535

RB3 is set as analog input by default, thus reading PORTBbits.RB3 always returns zero.

You can either setup RB3 as digital port through AD1PCFGL or manipulate LATB instead of PORTB.

Code:

#define LED1    LATBbits.LATB3

- - - Updated - - -

To debug the code yourself, you can perform source level debugging in Proteus, importing the xc16 .cof file. But debugging is probably much more comfortable with MPLAB simulator.

Code:

AD1PCFGL

not configured. Analog function has to be disabled and Led pin has to be made digital output pin.

dsPIC33 doesn't run at 5V VDD. By default VDD in "configure Power Rails" of Proteus will be 5V. You have to change it to 3.3V or 3.6V for working with dsPIC33.

AD1PCFGL not configured. Analog function has to be disabled and Led pin has to be made digital output pin.

LED pin is already configure as output in the code. Default AD1PCFGL=0 doesn't prevent output function, just blocks port read-back.

dsPIC33 doesn't run at 5V VDD. By default VDD in "configure Power Rails" of Proteus will be 5V. You have to change it to 3.3V or 3.6V for working with dsPIC33.

Proteus hardly cares about...

Thanks FvM.

You are right. for loop state is infinite, so that it is not running.

Re: dsPIC33FJ32GP204 Timer1 is configured using datasheet but not working

Buttons need debouncing.

You are controlling LED1 from two places that in from main loop and also Timer ISR. If it is turned ON in Timer1 ISR then immediately it is turned OFF in the main loop's first else condition and so you will not see Led toggling.

andre_luis · Dec 30, 2017

Buttons need debouncing.

Debounce is needless in this case where the only function of the input reading is to mirror the current state of the key toward the LED, no counting being made, so this is unrelated to the issue itself.

Anyway, as long as the OP saves words and does not tell exactly what is "not working", the rest will be guesswork.
