18F45K50 Portd And Porte Issues

Recommended Posts

Hello,

 

When I compile the following I get errors relating to unknown registers on the 18F45K50 device.

 

trise = 0x00;

 

LKPSU_Firmware.c(2716:25): error: unknown identifier 'trise'
LKPSU_Firmware.c(2716:25): error: invalid operand 'trise'

commands to portd also generate errors but not as straightforward. the FC_CAL function is my abstraction function which works well on other devices.

 

LKPSU_Firmware.c(6126:12): error: invalid operand 'FC_CAL_Port_In_DDR__x((&FCP_PORT_D), (&FCP_TRIS_D), ( 0x1), ( 0x0))'
LKPSU_Firmware.c(6126:8): error: failed to generate expression
LKPSU_Firmware.c(6163:43): error: invalid identifier

Is there any way I can fix this? I have promised firmware to the Chinese for December the 25th and have it all done and ready to go except it won't currently compile on this device!

Managed to make it work correctly by changing this in the BoostCPic18.h file. Might be other things lurking!

 

#ifdef _PIC18F45K50
- #include <PIC18F24K50.h>
+ #include <PIC18F45K50.h>
#endif // _PIC18F45K50

 

 

And this change in the PIC18F45K50.h file.

 

volatile char ccp2con @CCP2CON;
+volatile char trise @TRISE;
+volatile char trisd @TRISD;
volatile char trisc @TRISC;

 

volatile char ctmuconl @CTMUCONL;
+volatile char late @LATE;
+volatile char latd @LATD;
volatile char latc @LATC;

 

volatile char porte @PORTE;
+volatile char portd @PORTD;
volatile char portc @PORTC;

Good to know! One would assume that the device headers are correct but not necessarily so.

 

Thanks for sharing the information.
