Hi guys, I'm using Googlium training board and for some reason It lost OSCCAL value. On Pickit 2 says invalid osccal value detected and when I try to regenerate it says programming failed at memory ad ...

Hi my PIC friends =), I found ENC28J60 on a MCU box at my university laboratory and I found out this one are used for the ethernet module. but this one is a 28 pin DIP package which I found very weird ...

Also, as a further comment, >> & << are the generic 'C' shifts. However for a rotation, you might want to look at the rotate_right and rotate_left functions:

int8 val=0b000000 ...

Hi guys, I'm the noob again haha ^^.

I'm still learning C code and PICs, and I always used to switch pins like this PORTBbits.RB0 = 1; for example to do a simple LED chaser, but I saw "< ...

#include <18F2550.h>
#fuses NOMCLR INTRC_IO
#use delay(INTERNAL = 8MHz)

The default clock rate for the internal oscillator is not the 8MHz branch. You have to specify this to b ...

Hi lads, I want to use the internal oscillator on 18f2550 but delays are not ok. Delays are critical in my project cause I need to use a range with delay_us.

#include <18F2550.h>
#fuses N ...

Does your button circuit look like this ? Or something else ?
In this circuit, when you press the button it puts Ground on the PIC pin.
When you don't press it, it has 5v on the pin.

Hi dear friends =) !

I made this code for pic12f675 interrupt and I got it working but I don't know why when I press the button it won't initialize the interrupt until I switch it off. If I hold ...

There is an option 'Program calibration memory'. This needs to be unchecked.

This is under:
Properties->Categories=PICkit 3->Option categories=Memories to Program

I´ve got it thank you b ...

Hello people, I have a question...

What program or tool do you use to develop an application for Windows to control the MCU over USB, how hard is it ?
I know how to interface an LCD, analog input ...

Some comments:
First you now begin to see how Proteus can mislead you.
Second erasing the calibration memory, is very carefully discussed in the data sheet. Including telling you that most programme ...

On the 675, this:

Buddy it worked!!! Thanks I been trying for so long! and would not figure this out in 10 years! =).

I'm using a 250ms delay and I measure it with the oscilloscope and is not ac ...

I gonna try it and tell you how it went, many thanks to you and the people of this community, coming from Arduino IDE this is some scary stuff. Everything is so raw =D.

I suspect PCM_programmer's suggestion that you have erased the chip fully, is probably the cause.
I've just tried this with 3.249, 4.099, 4.141, and 5.066, and with all it runs fine.

So, do what h ...

not even blink an LED
Post your test program to blink an LED with CCS. We want to see the
#include line for the PIC, the #fuses statement, #use delay(), main(), etc.

Also post a link to the sch ...
