Hellow

Where can I find following files:

tDMAChannel.h, tDMAChannel.cpp

tDMABuffer.h, tDMABuffer.cpp

tLinearDMABuffer.h, tLinearDMABuffer.cpp

tMITE.h, tMITE.ipp, tMITE.cpp.

Thanks

Download dma.zip located here:

In it you will find the following sources:

dma.mak
tDMABuffer.cpp
tDMABuffer.h
tDMAChannel.cpp

Hellow, thanks for answer.

One more question:

u32 getCalibrationAreaOffset (const u8 *eepromMemory)

{

    return (eepromMemory[kCalibrationAreaOffset] << 😎 | eepromMemory[kCalibrationAreaOffset+1];

}

In function getCalibrationAreaOffset construction (eepromMemory[kCalibrationAreaOffset] << 😎 always equal 0, as since (eepromMemory[   ] have size u8. Is there sense here?

Thanks

What compiler are you using?

Can you post your definition of u8 here?

Hellow.

I use GNU Compiler Collection (4.3.3) under QNX Momentics IDE.

Function u32 getCalibrationAreaOffset (const u8 *eepromMemory) looks in my code as:

uint32_t getCalibrationAreaOffset (char* eepromMemory)

{

    return (eepromMemory[kCalibrationAreaOffset] << 😎 | eepromMemory[kCalibrationAreaOffset+1];

}

Objects of type char (and u8, I think) have size 1 byte. But then operation <Object of type char> << 8 always must be equal to 0. Am I wrong? Why?

What real value (offset) will getCalibrationAreaOffset return for PXI-6255?

Thanks
