I2C übersetzungsfehler

Ich möchte mein RP6 Control Board als Slave betreiben.

aber ich bekomme immer eine Fehlermeldungen dieser Art:
C:\...\Informatik\RP6\RP6CONTROL_EXAMPLES\!I2C_Sla ve/I2C_Slave.c:14: undefined reference to `I2CTWI_writeBusy'
...I2C_Slave.c:14: undefined reference to `I2CTWI_writeRegisters'
...I2C_Slave.c:112: undefined reference to `I2CTWI_initSlave'

Code:

---

// Includes:

#include "RP6ControlLib.h"                // The RP6 Control Library.
                                                                // Always needs to be included!
#include "RP6I2CslaveTWI.h"
#define I2C_RP6_Control_ADR        0x0A

/*****************************************************************************/

void LCD_data(void)

        if(!I2CTWI_writeBusy && I2CTWI_writeRegisters[1])
        {
               
                uint16_t adcLSL = I2CTWI_writeRegisters[1]*256+I2CTWI_writeRegisters[2];

da kann doch nur irgendein Fehler mit #include "RP6I2CslaveTWI.h" sein

mfg WarChild

guck mal in makefile, da ist aufgelistet, welche .c dateien includet werden. evtl. musst du da die kommentierung, also das '#' vor dem i2c.c entfernen.

vielen dank...
