DSC56f803X Interrupts

guenerylaurent — Wed, 27 Feb 2019 20:50:18 GMT

Hello

I don't find the documentation about the interrupt using for Codewarrior Eclipse version 11.0 with MC56f8037 (without processor expert).

I use the #pragma directive for the C code interrupt function, but I don't find how to setup the interrupts vectors table.

Tank you

Laurent

Hi, Laurent,

Pls refer to the screenshot, The MC56F803x_vector.asm is the vector table. The tools is CodeWarrior for DSP56800E ver8.3.

Hope it can help you

Hello

Tank you for your help!

My problem was the "F" in front of my function name in my MC56F803x_vector.asm.

Hi, Guenery,

If you define the api function in C code, you want to call it in the *.asm, you have add the prefix "F" at the function name. BTW, maybe you have to add the line XREF Fxxx so that the compiler knows the function is defined outside of the *.asm file.

Hope it can help you
