TAS3204 I2C initialize

Other Parts Discussed in Thread: TAS3204

Hi there,

I'm building my own component and I have much problems with the initialization of biquad coefficients.

For example the filter coefficients for my biquad filter I default set to

b0 = 1,0 b1=0,0 b2=0,0 a1=0,0 a2=0,0

When running my component in a project some coef that should be 0,0 is set to 1,0 resulting in strange behavior. Have someone else experienced this problem? What is the solution for this?

I use TAS3204EVM for development and PPS v1.88 build 3

Best regards

Helge

    Helge,

        We are aware of one bug that haunts only the TAS3204 with PPS 1.88b3, which may be the solution to this problem. This will be resolved in the next release, however please insert the following    '/zerocoefinit'    (minus with single quotes) in the additional Assembler options of PurePath Studio. I suspect this workaround will resolve this issue, but let us know if it doesn't.
