hello everyone,
i'm getting following errors while compiling the codes for my controller:

C:\Users\admin\Downloads\arduino-1.0.1-windows (2)\arduino-1.0.1\libraries\LiquidCrystal\LiquidCrystal.cpp: In member function 'void LiquidCrystal::initSPI(uint8_t)':

the liquid crystal.h was downloaded from Arduino Playground - LiquidCrystal Library

Put "#include <SPI.h>" before the include of the library, just as it is in the example.

Did you try the proper capitalization: <SPI.h>?

Hi,

Thanx for the help. I'm also facing the same problem. I've tried all possible caps/without caps includes, but he error persists.
I tried these one by one:
#include<spi.h>
#include<SPI.h>
#include"spi.h"
#include"SPI.h"

Here is the line of code where there is error message:

Adafruit_CC3000 cc3000 = Adafruit_CC3000(ADAFRUIT_CC3000_CS, ADAFRUIT_CC3000_IRQ, ADAFRUIT_CC3000_VBAT, SPI_CLOCK_DIV2);

Error message: 'SPI_CLOCK_DIV2' was not declared in this scope.

Kindly help me in this regard, i'm stuck in the project i need to deliver.

regards.

farrukhlodhi:
Error message: 'SPI_CLOCK_DIV2' was not declared in this scope.

That constant should be defined by SPI.h. Perhaps if you showed all of your code someone could figure out why the declaration is not happening.

If you check the SPI.h , 'SPI_CLOCK_DIV2' is defind there.
so it means that your library is not added Properly. follow below thread it may help you.
