Please Can you help with a school project?
Note I am using a program Micro-C

I’m looking for how store variable on flash instead ram. In AVR-gcc is simply, but in XC 32 or 8 i can’t found this one

Sir;
I need a pic16f877a in mplab x ide program of when switch is pressed led on and again switch is pressed led off.

Hi Ligo George, thank you for this content,,,,i brought your product(programmer) from eBay and followed all these steps exactly,but i am getting this error(red under line) “cannot find include file “.When i build this program,the program build successfully,but led is not blinking.(MPLAB X IDE V3.60,electrosome programmer,pic16f877a,pickit2 are used here). Please help.

what is the changes when I use dsPIC30F2020 instead?

you could also use this , for (int i = 0;i <20;i ++) _delay_ms(50);
As 20 x 50 = 1000 ms which is one second

Kindly use our forums ( https://electrosome.com/fourms/ ) and put your complete code there.

I’m trying some basic stuff on the PIC18f4455 and for some reason I can’t change the voltage level on the pins. Code compiles, downloads into the chip, but that’s it. No blinky, no nothing… Any ideas? ADC is turned off, btw.

If the error is inline delay argument too large, you need to make a user defined function and call it.

like this :

void Delay10(unsigned a)
{
for(;a>0;a–)
{
__delay_ms(10);
}
}

What error ?

like this…..

This is the image

Thank you for the information I will give that a try.

Thanks for this tutorial, this works really well. How can i use this block of code 3 times in a program? I want different delay times that I can input from a switch. I cannot figure out how to activate only one at a time.

hello LIGO,

May i have your Email-ID

1.) I Am using Pic18F4520 Controller.

i have made my mclr pin positve i.e +5V applied to it.

also used crystal of 10Mhz hence capacitor of 15 pF. and in config had selected oscilator mode as HS.

I have wrote a program to blink led but it’s not working practically but in simulation it’s perfectly fine.

2.)One more i found that i have to insert a small wire at pin NO. RB5 the on the PIC DEM 2 Plus (old) it’s working fine

Plz help me..

i am attaching my code.

My main Program:

#include

#include

#include

#include “_config.h”

#include

void delay(unsigned char x)

{

for(unsigned char i=0;i<=x;i++)

for(unsigned char j=0;j<=135;j++);

}

void main()

{

while(1)

{

TRISB= 0;

LATB = 0xFF;

delay(100);

//LATB = 0xF0;

//delay(250);

LATB = 0x00;

//delay(100);

//LATB = 0x0F;

delay(100);

}

}

Hi Ligo. Can you tell me please, is it a big difference between HiTech C and XC8? I mean a have a HiTech source code and I would like to transfer to XC8 as my device (PIC18F26K22) not supported by HiTech C.

Hi, I don’t understand what you are saying.
You can build above code with XC8 compiler with MPLAB X IDE.

It will depend on the PIC you are using… Above tutorial uses PIC 16F877A

1. Go to “Run” in the dropdown menue

2. Choose “Set project configuration”

3. Choose “Customize”

4. When the window opens, choose “XC8 compiler” under the “XC8 global options” in the categories window.

5. Ensure that “Preprocessing and messages” is selected in the “Option categories” drop down menu.

6. In the “Include directories” section add the directory that the plib.h header refers to ( c:/program files (x86)/microchip/xc8/v1.xx/include/plib). Once that is done, it will not give the error flag.

Just change RB0 to LATB0..
You can edit the configuration in in MPLAB IDE itself .. and copy the settings to your code. .as described above..

I don’t know… Post this question in Microchip’s forum…
It might be the problem with you PC.
