usb code help
hello
i want to write a code in high memory of pic18f4550 so i modified the pbppic18.lib file and changed ORG RESET_ORG + 8 to ORG 27040 as explained in this post: http://www.picbasic.co.uk/forum/show...4622#post24622
now i created a simple program as below, it worked and i am able to write this code in high memory of 18f4550 starting from 27040(69A0H)
Code:
define LOADER_USED 1
DEFINE OSC 48
adcon1 = 15
@GOTO 0x0040
however the below code does not care about DEFINE LOADER_USED 1 parameter and i am unable to program it on my defined location.
Code:
define LOADER_USED 1
DEFINE OSC 48
adcon1 = 15

DEFINE USB_PLUGGEDLED PORTB,0 ; LED indicates if USB is connected
DEFINE USB_TXLED PORTC,2 ; " " data being sent to PC
DEFINE USB_RXLED PORTC,1 ; " " data being received from PC
main:
@ ON_USBRX_GOSUB _HandleRX
pause 10
goto main
HandleRX:
if USBRXBuffer[1] == "S" then
@GOTO 0x0040
else
ARRAYWRITE USBTXBuffer,[STR USBRXBuffer\USBBufferSizeRX]
GOSUB DoUSBOut
endif
return
can any one tell me why the first program is considering the define LOADER_USED 1 parameter and the second one is ignoring it.
thanks
