Hello,

 

Could you suggest the way how we can  get the real time data(ADC data) through UART in AWR 1642ODS hardware.

 

Regards

Resmi

    Hi,

    You would have to write an application running on the AWR1642 DSP that would copy the raw data and would transfer it through UART to a host.

    Notice that you would be limited by the UART bandwidth. Depending on frame rate, number of ADC samples and number or chirps, at some point you would not have sufficient time to transfer the data through the UART. However for small number of Chrips this may work.

    The easiest way would be to modify the mmWave SDK 2.1 AWR1642 Demo. Even if this demo was developed for AWR1642BOOST EVM, in this case you don't care because you are not interested in processing that data, You only would want to transfer it.

    However the code would have to be modified to copy the ADC data to L3 memory and send it using the UART to the host. On the host you would run some matlab script similar to the GUI provided for the AWR1642ODS demo that would read the UART data and save it to a file.

    thank you
