Stream ADC data and timestamp to Ethernet RJ45

[Power_tile]

Hi, I am trying to stream ADC data to ethernet RJ45 port along with synchronized timestamps. Currently I am trying to figure out the following problems:

 

1. How can we synchronize ADC data with timestamps? The STM32 tutorial uses DMA, which I assume directly put the ADC samples to the memory but guarantees no synchronization with timestamps.

2. How can we stream the data out through ethernet port? The H7 boards datasheet says the RJ45 port is connected with the MCU using "RMII interface" - however, I wasn't able to find anything related in the STM32 tutorial. Are there any existing libraries?

 

I am using an STM32H723ZG evaluation board. Thanks!

PS: STM32H723ZG is not an evaluation board but I think you meant NUCLEO board.
