Here is my plan: I would like to use the pic18f2455 to create a web server. I am not going to use ethernet or eeprom. I will connect it to my pc with the serial cable. The other end of the cable will connect to the serial port of the pic. The pc will connect to the pic with slip for the web server and with hyperterminal instead of the lcd of picdem.net. Does this sound o.k.? 2. In compiler.h I find #define CLOCK_FREQ (20000000) // Hz As I am planning on using the internal oscillator of the pic, which is 6mhz, do I need to change this value? and if so is clock frequency the same as the oscillator frequency? 3. Do I need to change TICKS_PER_SECOND and TICK_PRESCALE_VALUE and if so how do I know what these values should be? 4. I have identified that I need to use the project file mpslpg.pjt because it has the slip, internal web pages (no eeprom) and the web server, but how do I use this file? I downloaded the C compiler and I couldn't find any gui environment? tia -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
