Hi sir

The exported .h file is too large, could you help check whether delete the initial value?

Hi Darren,

Generally speaking, the length of .h file is related to how many features are activated.

For example, one biquad needs 5 * 32 bits initialization script, so the length of both left / right 15 biquads are 20 * 5 * 32 bits.

Anyway, PPC3 also support to generate only active components at the setting button. You can try to disable the default features.

Hi Darren,

'5805 did not answer' - Does it mean the I2C communication is wrong? If yes, please check the I2C address firstly, and this part can be found at TAS5805 datasheet 9.5.2 Slave Address part. (pay attention to the difference of 7 bits address and 8 bits address)

One more question, which platform is used at your side?

Matthew

Hi Darren,

The 8 bits address with your system should be 0x5a. However, for main platform, I think maybe you can try to use 7 bits address 0x2D.
