| Invalid Pre-Processor directive Invalid Pin |

I'm using MPLAB X IDE v5.15, CCS v5.078 to develop the firmware for a PIC24FJ1024GB606.
I need two USARTs and two SPI, so I defined those pins this way
| Code: |
//GSM
#pin_select U1TX=PIN_B7
#pin_select U1RX=PIN_B6
#pin_select U1CTS=PIN_B9;//IN
#pin_select U1RTS=PIN_B8;//OUT
//GPS
#pin_select U2TX=PIN_D5
#pin_select U2RX=PIN_G9
//ACELEROMETER BUS
#pin_select SDI1=PIN_D3;//INPUT
#pin_select SDO1=PIN_D4;//OUT
#pin_select SCK1OUT=PIN_D2;
//MEMORY BUS
#pin_select SDI2=PIN_B4;//INPUT
#pin_select SDO2=PIN_B5;//OUT
#pin_select SCK2OUT=PIN_B0;
#use rs232(UART1,stream=GSM,NOINIT)
#use rs232(UART2,stream=GPS,NOINIT)
#use fast_io (ALL) |
All is ok except the CTS/RTS and the SPI definitions.
I'm new on 16bit microcontrollers so probably I just made a really dumb mistake.
Would you help me please?

Quick comment...
While I don't use that PIC but.. the error looks like you're trying to use a pin that cannot be used as you want.
You'll have to look/read the section on 'pin select' and see what's legal to use. Not all pins can be connected to all internal peripherals.......

Yes, I read the header file.
| Code: | // #pin_select function=pin
// Valid Pins:
// PIN_B0,PIN_B1,PIN_D8,PIN_D10,PIN_D9,PIN_B6,PIN_B7,PIN_B8,PIN_B9,PIN_F4,
// PIN_D0,PIN_D11,PIN_B2,PIN_B14,PIN_F3,PIN_F5,PIN_B5,PIN_G8,PIN_D5,PIN_G6,
// PIN_D3,PIN_D2,PIN_D1,PIN_D4,PIN_G7,PIN_G9,PIN_B4,PIN_B15,PIN_C14
// Input Functions:
// OCTRIG1,INT1,INT2,INT3,INT4,OCTRIG2,T2CK,T3CK,T4CK,T5CK,IC1,IC2,IC3,OCFA,
// OCFB,CCPCKIA,CCPCKIB,U3RX,U1RX,U1CTS,U2RX,U2CTS,SDI1,SCK1IN,SS1IN,U3CTS,
// SDI2,SCK2IN,SS2IN,TMRCLK,CLCINA,CLCINB,U4RX,U4CTS,SDI3,SCK3IN,SS3IN
// Output Functions:
// NULL,C1OUT,C2OUT,U1TX,U1RTS,U2TX,U2RTS,SDO1,SCK1OUT,SS1OUT,SDO2,SCK2OUT,
// SS2OUT,OC1,OC2,OC3,CCP4OUT,CCP5OUT,CCP6OUT,U3TX,U3RTS,U4TX,U4RTS,SDO3,
// SCK3OUT,SS3OUT,C3OUT,CCP7OUT,REFCLK,CLC1OUT,CLC2OUT,RTCCOUT

Something similar was discussed here less than a week ago if I remember correctly. For SPI functionality you also have to specify a serial clock in pin. Read the topic below and see if it makes at least some of the errors go away.

| I'd still read the Microchip datasheet ! There could be a 'bug' in the compiler, always best to confirm with the manufacturer of the PIC to know what's legal. |

I found the mistake and as I had said it was really silly.
The mistake is that preprocessor commands DOESN'T NEED A SEMICOLON!!! 
What an idiot!!

Been there. Got the 'T' shirt...
If I had a pound for every 'silly' like that I did, I'd be richer than master B.
