I am using PIC18F45K22. On that microcontroller is "installed" bootloader. I am using Free MikroC PRO for PIC for generating .hex program files. When i make C code i build .hex with MikroC Pro for pic. Then i use mikroBootloader to load .hex on PIC. I have usb to serial converter linked with my PIC. Everything is working perfect.
Now i want to use MPLAB X with CSS or XC8 compailer. Can i generate .hex file with MPLAB X and then load it on PIC with mikroBootloader or something like this.(bootloader code is already on PIC).
I can load .hex files generated with MikroC pro for PIC can i do the same with MPLAB X or not. If yes how. I already tried couple of times but useless.
If there is some tutorial or guide please... I cant find info about my problem.
 

Can i generate .hex file with MPLAB X and then load it on PIC with mikroBootloader or something like this

You can do it.

Compile MPLAB C18, XC8 or CCS C project and get the .hex file. Open mikroC PRO PIC and then open mikroBootloader app. Connect to device and load .hex file and then upload.

My code in MPLAB X with XC8 to turn LEDs on PORTB6 and PORTB7. I have test circuit with MikroC pro for PIC. Its working. Then i create this code.. And when build main project in MPLAB X gives me no error. Then i go to project directory/dist\default\production and there is .hex file. I load this file with MikroBootloader on PIC restart it but nothing happens... I dont know what to do. I havent even turn anything on with MPLAB X XC8 nothing seems to work.

hello,


With MPLAB C18, you must once use "export" the hex file, to get the config bits inside...
i don't know if with XC8 this problem still exist.
.Try to load the MikroC HEX version, then the MPLAB HEX version into Pickit3 program
to compare the config bits reading...
 


Dont know how to do it. I dont have Pickit3. I have created confing bits in MPLAB code configurator. I set all the confing bits. I have opened MikroC pro for PIC and there looked for config bits and in MPLAB X clicked every confing bits to the same value as in MikroC. Then MPLAB code configurator create this code i just copy and paste it in c code. I set osc freq to 8mHz and try to set PORTB but useless. When load hex with bootloader the previus program is deleted on PIC but new one created with MPLAB X dont work.
 

That means that my coding in MPLAB X XC8 is not right. I must solve my problem with making right project with right coding. It must work..!
 

My Confing in MikroC pro for pic:

And my config in MPLABX CX8 with code:

void main() {
    
    ANSELA=0;
    ANSELB=0;
    ANSELC=0;
    ANSELD=0;
    
    
    TRISA=0;
    TRISB=0;
    TRISC=0;
    TRISD=0;

    
    LATAbits.LATA1 = 1;
    LATAbits.LATA2 = 1;
    LATAbits.LATA3 = 1;
    LATAbits.LATA4 = 1;
    LATAbits.LATA5 = 1;
    LATAbits.LATA6 = 1;
    LATAbits.LATA7 = 1;

    PORTBbits.RB0=1;
    PORTBbits.RB1=1;
    PORTBbits.RB2=1;
    PORTBbits.RB3=1;
    PORTBbits.RB4=1;
    PORTBbits.RB5=1;
    PORTBbits.RB6=1;
    PORTBbits.RB7=1;



    PORTC=0xFF;

    LATD=0xFF;

}

All the configuration bits are same in MikroC and MPLAB, but when i load .hex from MikroC pro for PIC its working, when i load code from MPLABX XC8 program doesnt working on PIC. But mikroBootloader tells me that uploading is finished sucessfully. Loading MPLABX XC8 code with mikroBootloader dont work...
Must i set some code offset in MPLABX ?
Is my code working on PIC?
 

I set XTAL to 8000000. Still not working...
I am thinking that i can not load .hex generated with MPLAB X XC8 on PIC with mikroBootloader...
