two serial ports

[Scampy]

Thanks for the comments guys,

Current PIC is an 18F4580. I use the standard serial comms to communicate with a PC applications. I'm developing the project to include additional sensors and as such need more real estate to display the results, so I've obtained a 128 x 64 FLCD, which with a similar font to an LCD, gives me 7 x 21 characters which is ideal.

I've also puchase a serial / i2c / SPI piggy back driver for the display, and at the moment have it running in serial mode as it was not wanting to do much more than control the back light etc. If I can get this running under i2c it would free up the TC/RX pins for either serial connection with the PC or the use of a serial wi-fi board mentioned above.

However I have 4 lines of code which simply fail to compile following the conversion from serial to i2c

i2cwrite SDApin,SCLpin,$00,$42,"TP",DEC1 Pid_channel+1,0

When compiled MCS states "Expected [ at line 743" and "Expected ] at line 743" but placing the brackets after the address and at the end, or any combo thereafter results in "Bad expression" error....

Any ideas
