PSoC™ 6

Hi,

I am using CY8C6136BZI-F14 of PSoC61. This device has only one I2S I/F, but I need another one. So, I am considering adding another I2S I/F using UDB. Is there any problems using it as described in KBA229971?

Thanks,

Kenshow

It's supposed to have no matter of concern to follow this KBA for your request.

Please try to follow the description and implement it.

If you get some problems with it, I'll take care of it.

Hi,

I have tested I2S of UDB on CY8CKIT-062-BLE. Unfortunately, it hasn't worked on PSoC6.

Is there a code example for PSoC 6 using DMA?

As it is, PSoC 6 won't be able to selected.

Thanks,

There is another way to implement an I2S Master. You could use SPI + Smart I/O. Please refer to this code example:

Thant's good idea. However, the CE is Tx only. Can I use Rx as well?

I need another Rx&Tx port.

It is possible to do I2S RX as well, but we haven't implemented in the code example. You probably need to use another SPI to implement RX, since SPI MOSI and MISO needs to be in sync.

Is there an opportunity behind this? You could create a MyCase to request help from Cypress/Infineon.

But if you are using PSoC Creator, you might be better off to simply use the UDB version.

I am using PSoC Creator. 

I will consider Mycase.

I'm not asking anything special, I just want to see how I2S (UDB) works and its CE, which is featured in KBA.

Thanks,

Sure. You can upload your project here, so we can take a look at it.
