how to download program demo for FRDM-K22F?I can't find the URL.
Hi Zha Ye,
You can download the MCUXpresso SDK package for the FRDM-K22F board from this link:
Welcome to MCUXpresso | MCUXpresso Config Tools
Here is a document that explains how to generate the SDK package:

thank you very much , I want to konw about sgtl5000 IC driver code on the Development Board of FRDM-K22F , but i can't find the demo program about this,Hope for your help.
Hi Zha Ye,
There is an example for TWR-K64F120M board (SDK_2.2_MK64FN1M0xxx12 package) that uses TWR-SGTL5000. In this example, fsl_sai_edma driver is used.The SAI is configured as Master (SGTL5000 as slave) and audio data is sent to codec by using DMA channel 0. SAI module is configured in Master mode, Asynchronous mode and Left justified format (default configuration) meanwhile audio is configure to use 16-bit format and sampling frequency is 16kHz.
I am attaching sai example source files for your reference which can be used with the fsl_sai_edma drivers included in the SDK package for the FRDM-K22F board.
Hope it helps!

Hi Carlos Mendoza,
Now, The setup up of sgtl5000 is complete. The I2S is configured as Slaver (SGTL5000 as slave) and audio data is recived from codec by using DMA channel . Asynchronous mode and I2S format meanwhile audio is configure to use 16-bit format and sampling frequency is 48kHz, mclk is 1.576MHz. It is mainly used to audio sampling, the route is LINK_L->ADC->I2S_OUT, now the i2s_out pin generate a signal to MCU , although i have not input audio simple, I am very confused now, this is normal or not?
Hope for your help.
sorry, I‘m wrong. ’The I2S is configured as Master (SGTL5000 as slave).
