Interrupt handlers

In the qs-scope example the interrupt vectors are declared and placed into the vector table in the startup file (startup_xxx.x depending on which dev tools you are using). Possibly this is the link you are missing?

For example, here are the relevant lines from the startup_ccs.c file.   

//*****************************************************************************
//
// External declarations for the interrupt handlers used by the application.
//
//*****************************************************************************
extern void DataAcquisitionADCSeq0IntHandler(void);
extern void DataAcquisitionAbortIntHandler(void);
extern void ClassDPWMHandler(void);
extern void SysTickIntHandler(void);
extern void UARTStdioIntHandler(void);
extern void USB0DualModeIntHandler(void);

//*****************************************************************************
//
// The vector table.  Note that the proper constructs must be placed on this to
// ensure that it ends up at physical address 0x0000.0000 or at the start of
// the program if located at a start address other than 0.

,OK, that is where they hid it.  I am using code composer studio.  What is the extension of the startup file that I should be using?

For CCS use startup_ccs.c.

I am also trying to add a int handler for my I2C routines and figured where I had to add it in the startup_ccs.c but when I compile & link, I get this error:

<Linking>

"../lm4f232h5qd.cmd", line 31: error #10099-D: placement fails for object

".intvecs", size 0x26c (page 0). Available ranges:

FLASH size: 0x40000 unused: 0x3fcac max hole: 0x3fcac

error #10010: errors encountered during linking; "Test Processor.out" not

built

I am using the dev kit with the LM4F232 part on it.

I have also tried this line instead of adding the startup_ccs.c file and I get the same error.

IntRegister(I2C0_MASTER_BASE,I2CIntHandler); // Hook the ISR

Thoughts?

Thanks, Jeff

I also use the dve kit LM4F232 and got the same problem to add the ISR in a SYS/BIOS project

I add a startup_ccs.c and got the same error message as Jeff.

How to add a interrupt in the SYS/BIOS project ?

Thanks
