Hello, I have a program in which I use two interrupt routines, one for Timer 0 and one for Peripheral (UART). My code looks like this: ;;---------------------------------------------------- PAGE org 0x000 goto Mainline org 0x004 ;;---------------------------------------------------- Int ; TMR0 Interrupt code retfie ;;---------------------------------------------------- org 0x020 ; peripheral interupt Int ; Peripheral (UART) interrupt code retfie ;;---------------------------------------------------- This yields a few assembly errors that I am unfamiliar with. It is my understanding that TMR0 interrupts to 0x004 and Peripherals interrupt to 0x020, which I have done here. However, I get errors to the tune of: ERROR[118]: ............................. Overwriting previous address contents (0020) on the lines for the peripheral interrupt. What does that mean? Have I set up these interrupts correctly? -Mike -- http://www.piclist.com hint: The PICList is archived three different ways. See http://www.piclist.com/#archives for details.
