You could delete them or comment them. And if the code you are using uses = those=20 leds then you should comment that on the code too. =20 Another approach (at least to let you compile) will be to replace the LEDs= =20 definition by a Nop(). Check if that works (of course it depends on the co= de). =20 If that works, is time to remove all the code in the project that is relate= d to=20 the LEDs. May be you took an example code that uses leds but they are not = part=20 of the stack as far as I remember, I hope this helps Regards, Mauricio ________________________________ De: Steve Maroney Para: Microcontroller discussion list - Public. Enviado: mi=E9rcoles, 1 de septiembre, 2010 15:06:42 Asunto: [PIC] Microchip TCPIP Hello gang, I'm attempting to use Microchips TCPIP stack with a PIC18F2550. There are pieces of code in the files from microchip that are related to buttons and LEDS that I think has to do with thier demo boards. I see where they are defined in Hardwareprofile.h. Again, I'm only using these files on a PIC18F2550, not a demo board or starter kit. =20 These buttons and LEDS are not letting me compile successfully. What am I doing wrong ?
