PurePath and AIC3254 input channel

Hi,

I'm using PurePath Studio 4.10 with a AIC3254 and have a question.

The AIC3254 have 3 different analog input channels but I can't find a way to select which channel to use in PurePath.

When using "Dec4xIn" it is routed using In1 on the AIC3254, is it possible to route this to In2 using PurePath?

The same question also goes for the outputs. HPL seems to be the default channel, but how do I route it to eg: LOL?

Hi Mikael,

To change routing you can use the control software or load a custom script within PurePath.

Hi J Arbona,

Thanks for the reply.

If I understands the answer correct the generated .h needs to be edited for the application and there is no way to generate a .h file with the correct routing?

Mikael,

Correct. PPS REG section of the .h file configures the registers for EVM use. In the customer's system this would need to be modified for their analog routing, PLL settings, etc.
