Creating PIC18F25K20 Port to FreeRTOS

I’m trying to create a PIC18F25K20 Port do FreeRTOS and although rtosdemo1, rtosdemo2 and rtosdemo3 compiled OK I got many warning messages.

I’m using: MPLAB C18 V3.46

In port.c ,

I needed to make the following changes:


Include defines to config:
#pragma config WDTEN = OFF
#pragma config FOSC = INTIO2
#pragma config XINST = OFF

Because there are slight difference in register:

Line 561 if( PIR1bits.CCP1IF ) to if( PIR3bits.CCP1IF )
Line 602 PIR1bits.CCP1IF = 0; to PIR3bits.CCP1IF = 0;
Line 643 PIE1bits.CCP1IE = portBIT_SET; to PIE3bits.CCP1IE = portBIT_SET;
Line 651 OpenTimer1( T1_16BIT_RW & T1_SOURCE_INT & T1_PS_1_1 & T1_CCP1_T3_CCP2 ); to

            OpenTimer1(T1_SOURCE_FOSC_4 & T1_PS_1_1 & T1_OSC1EN_ON & T1_SYNC_EXT_OFF & T1_16BIT_RW , TIMER_GATE_OFF & TIMER_GATE_POL_HI & 	 TIMER_GATE_TOGGLE_OFF & TIMER_GATE_1SHOT_OFF & TIMER_GATE_INT_OFF);

///////////////////////////////////////////////////////////////////
In ParTest.c:

Modified PortD to PortB
PortE to PortC

////////////////////////////////////////////////////////////////////
Renamed : timers.h in C:\FreeRTOSV7.6.0_PIC18F25K80\FreeRTOS\Source\include to timers_.h because
there are a conflict with timers.h in C:\Program Files\Microchip\MPLABC18\v3.46\h
during compilation.
////////////////////////////////////////////////////////////////////
Before compilation it is necessary to set the “Build Options” of MPLAB:

        Hex format : INHX32
        Memory Model:
                      Code Model -> Small Code Model
                      Data Model -> Large Data Model
                      Stack Model-> Multi Bank Model

        Generate Command Line -> uncheck -> Extended Mode

Finally I ask anyone: How to correct port.c to avoid the “Warning Messages”?

I’m afraid we don’t encourage the use of FreeRTOS on PIC18 devices, the architecture and non re-entrant compiler do not make it a suitable target. I’m also not sure what Voloviq is, but if you got the code from Voloviq I suggest you ask whoever created or maintained Voloviq for support.
