I will use the STM32F769I-DISCO (which I explained earlier, see below) to build a recorder to the SD card with a touch interface. There is little documentation, but it is definitely supported: “Communication using DMA for control and user channel information”. Do you have any better idea for hardware? > [@S/PDIF input to USB, is ITTS in I2S?](https://forum.dccmuseum.com/t/s-pdif-input-to-usb-is-itts-in-i2s/51/5): > > I fully agree that we shouldnt replicate it. But googling I found an interesting [application note](https://www.st.com/content/ccc/resource/technical/document/application_note/group0/c5/67/84/35/7e/4c/4c/19/DM00431633/files/DM00431633.pdf/jcr:content/translations/en.DM00431633.pdf) by ST Micro from 2018. The STM32F4/F7/H7 ARM microcontrollers are able to transmit receive S/PDIF including user data and have lots of IO options like USB, Ethernet, Micro SD, Multitouch Touchscreen and HDMI. A great value dev kit is avaible for under USD 90, what are your thoughts on it for a first look on the specifications?
