First question asked Welcome!

Any example of reading 32-bit I2S PCM data with XMC4500 using DMA, which is how it is usually done in other MCUs like Microchip, Texas Instruments, STM, etc.?

With all my best,

Rajiv.

Hi @jameswbush ,

Apologies to get your query unanswered on your older thread here : XMC4500 32-bit I2S PCM support .

Unfortunately at the moment, we do not have any such code example that meets the requirement of implementing audio playback and record using DMA on XMC device. However, we have an alternative from our PSoC device family that might interest you. Please refer this code example here : https://github.com/Infineon/mtb-example-psoc6-pdm-to-i2s . This example demonstrates how to route Pulse-Density Modulation (PDM) audio data to the Inter-IC Sound (I2S) interface in PSoC® 6 MCU.

Hope this answers your question.

Best Regards,

Aashita
