I have a project that uses a Dallas 1307 clock chip. Got the code working but the clock runs a little fast, gains about 2 seconds a day. What can I do to slow it down a bit? I'm thinking that a small trimmer cap connected to one leg of the crystal to ground might work but I don't have any to try and don't know what value is needed so I don't know what to order. Also if I build another on...

Hi all, I've an oddball question. I've just installed MPLAB 8.14 and C18 3.21 on a system and tried to build my projects. They fail because C18 gives a syntax error on any macro that I try to use. I've done this install on two other systems and had no problems. They are all XP pro setups too. Has anyone else seen this behavior and fixed it? I'm assuming that I must have twiddled...
