Hi,
I want to make a CAN bus demo development board, for which I would request for suggestions for suitable micons from PIC. I have following criteria.
1. Should be DIP ( greater than 28 pins)
2. Should have decent RAM (8K)
3. Should be programmable through PICKIT 3.
4. 8/16 bit
5. Is available...
Hi,
Just gone through following link for 'advantages of function pointers' which can be helpful.

Hi,
The ECAN peripheral is possible in the DSPIC33FJ64GP804 IC that you have mentioned. The same has been given as in the below table in the datasheet (Link : https://ww1.microchip.com/downloads/en/DeviceDoc/70292D.pdf).
Excerpts from Datasheet: (11.6 Peripheral Pin Select)
The peripheral...

Hi,
It seems difficult to handle the 4 switches i.e B1, B2, B3, B4 (assuming the image shows push button switches) through 2 pins of the PIC.
However this problem can be resolved can be attemepted by following 2 ways:
Approach 1:
Either use on off switch instead of push button switch, in that...
Hi,
I suppose the PWM duty counter register used for p18f4431 need to be analysed properly.
The Period register (PTPERL, PTPERH) are 12 bit(8bit+4bit). Hence the Duty register (PDCnL,PDCnH) should also be 12 bit as it would be compared against the period register. But in the data sheet it is...
3 separate resistors with 2 switches can be used to make more than 4 combinations for ADC input. like
Patterns S1 - Switch 1 S2 - Switch 2 Output voltage at ADC
1 Open Open R1
2 Close Open R2/(R1+R2)
3 Open Close...
Yes, it worked on 7.7 sp2 for PIC16f628a micon. Can you check the voltage across LEDs (if LEDs are really getting the driving volages) .
I have attached image with LEDs in ON state on both the pins.
Also attached image for settings window.
Hi,
I have tried to set RA7, RA6 as output ports in ISIS(without defining the "__CONFIG()" in the code) in the "Edit Properties" of the Micon(PIC16f628a).
Try to set the value of "Program Configuration Word" as 0x2150, with this the pins can be set as output. The version on which I have tried...
Hi ragul07,
Cheer up!!
There's nothing wrong in your code. I have tried your code ("LCD_Test.txt") with header file("delay.h") on MPLAB ver2.00. (Hope you have the definition of "DelayMs()" in your "delay.h" file, as I had to edit this file to add this function).
After compiling the code on...
Thanks Brian,
for suggesting the circuit regarding addition of 5W resistor.
I am attaching the circuit diagram for the existing circuit and the modified one for confirmation.
I have a 12V 2Amp DC Adapter. I have designed a power supply circuit using 7805(without heat sink). I want to give the output of the adapter as the input to this power supply circut. But as per my study 7805 shuts down in case current goes beyond >600 mA, and so the output at 7805 is not...
