init_MC104P(); // configure MC104P inputs, outputs, analog and pc104 bus
init_cirrus_video(); // initialize the VGA video card with the Cirrus Logic
do
{
output_F(i);
setup_adc_ports( ALL_ANALOG );
setup_adc(adc_clock_internal);
set_adc_channel(0);
k[i]=read_adc();
delay_us(50);
set_adc_channel(1);

You have declared a _prototype_ for a function called MC104P, but have no defintion for the function init_MC104P at all....

MC104P()
and
init_MC104P()
are two completely different functions. You've delcared MC104P() but are trying to call init_MC104P(). I'm not sure what you're trying to do with the init_ before MC104P().
Plus, you are calling init_cirrus_video() but have no definition for it so it will choke as well.

This is very important information. I had a look at the website of Calmotion and downloaded the Software & Examples Manual.
On page 2 of this manual it reads: | Quote: | Requirements
All of the libraries used as examples in this manual were created using the C18 library builder from Microchip. The compiler and linker used for your project must be compatible with this library builder. |
The error messages you get are caused by several functions being defined inside the libraries, the compiler can't find these functions.
Which compiler version are you using? Only in the new v4.xxx CCS compilers the use of libraries is supported. The v4.xxx compiler is still very new and contains many bugs, the v4.03x versions seem to be the first more or less stable versions. I have read many problems about the use of libraries but don't know the status for the v4.032 version, maybe someone else can answer on this?
Does someone know if the Microchip C18 libraries are compatible to the CCS compiler? |
