Mark, I have been using the CCS compiler for about a year now and am very pleased with the results. The Serial, I2C, and SPI functions included in the library that comes with the compiler all worked great, no modifications were needed. I was happy with the LCD functions I had written previously, so I haven't tried those out, but they are included. I felt for the $99 I spent on it, I really got my moneysworth back.
