I'm trying to get my head across the DT Interrupt code for a small new RC modeling project and I'm trying a test example first (the blinky LED) , compiling with MCS. I have 12f683 selected in MCS and MPASM being used.
but I get an odd warning message from MCS thus :
Warning[219] d:\pbp code\pbp\pbppic14.lib 336 : Invalid RAM location specified
Warning[219] d:\pbp code\pbp\pbppic14.lib 892 : Invalid RAM location specified
Anybody know why and if I should just disregard it ?
I commented out the wsave lines as required (which led me here BTW)
My code
Code:
LED1 VAR PORTB.1
INCLUDE "DT_INTS-14.bas" ' Base Interrupt System
INCLUDE "ReEnterPBP.bas" ' Include if using PBP interrupts
ASM
RBIF = GPIF
RBIE = GPIE
INT_LIST macro ; IntSource, Label, Type, ResetFlag?
INT_Handler TMR1_INT, _ToggleLED1, PBP, yes
endm
INT_CREATE ; Creates the interrupt processor
ENDASM
T1CON = $31 ; Prescaler = 8, TMR1ON
@ INT_ENABLE TMR1_INT ; enable Timer 1 interrupts
Main:
PAUSE 1
GOTO Main
'---[TMR1 - interrupt handler]--------------------------------------------------
ToggleLED1:
TOGGLE LED1
@ INT_RETURN
My project is quite simple. A 22.5mS interrupt timer (TMR1 I guess) and toggle a few pins then wait for the next interrupt.
