Hi.

I put CC2533 I2C code in CC2541 simpleBLEPeripheral project to use I2C.

But when I try to use HalI2CRead function, Error[e46] comes out.

Error[e46]: "HalI2CRead::?relay" referred in simpleBLEPeripheral (C:\Texas Instruments\BLE-CC254x-1.2.1\Projects\ble\SimpleBLEPeripheral\CC2541DB\CC2541\Obj\simpleBLEPeripheral.r51

I already put #include "hal_i2c.h" and hal_i2c.c" and copy those two files into the C:\Texas Instruments\BLE-CC254x-1.2.1\Projects\ble\SimpleBLEPeripheral\Source.

I don't know what is the problem.

Help Me!

Have you added hal_i2c.c and hal_i2c.h to your project in the ide? You should only be including the .h file. Is #include "hal_i2c.h" at the top of your simpleBLEPeripheral file?

Hi,

In addition, the search path to the i2c header should be known to the compiler.

You can check whether the to i2c files is also included in IAR search paths by opening

project options->C/C++ Compiler->Preprocessor->Additional include directories (sub window).

Hi.

First, I erased #include "hal_i2c.c".

And I check that project options, but it seems that IAR cannot be connected i2c file.

What I did was I paste hal_i2c.h files to all of the directories.

But it still show me same error, e46.

What is the problem?

Regards

I solved the problem.

I put those two lines in <simpleBLEPeripheral.c>, <hal_i2c.h> and <ioCC2541.h>.

#define HAL_I2C TRUE

#define HAL_I2C_MASTER TRUE
