Solved

Hello Avnet community,

I'm using the I2S interface on the IoT Board with the wiced sdk. The wiced sdk calculate the PLL registers from some constants in the platform configuration. After the configruration the I2S interface works but it runs with a wrong frequency.

So they need the PLL_M_CONSTANT and the HSE_VALUE. They are provided through the platform_config.h and the Make file.

PLL_M_CONSTANT is 15

HSE_VALUE is 26000000

 

Can you make sure these are the right values? Maybe there is a wrong value in the platform files.

Maybe some else uses the i2s interface with the right frequencies and can provide some more information

Hopefully I get an answer :)

Best advice I can provide on this is to recommend that you post your I2S questions to the applicable Cypress WICED forums
