AWR1843AOPEVM: AWR1843AOP

Nicky Rosenberg
Prodigy 10 points
Part Number: AWR1843AOPEVM
Other Parts Discussed in Thread: IWR1443BOOST, , AWR1843AOP

I want to communicate and operate the demo program (or modified demo program) on the AWR1843AOPEVM and IWR1443BOOST using the 3.3V RS232 interface at any baud rate up to 5M.

This should be instead of using the USB (or Bluetooth on AWR1843AOPEVM) interface which expands to 2 serial ports on a PC.
Is it possible? and if yes, how do I do it?
On IWR1443BOOST the USB creates 2 serial ports (command and data) and the schematic shows only one RS232 interface available (AR_RS232TX and AR_RS232RX) after populating 2 DNP resistors, so how the interface will work? The firmware should be modified? or there is another RS232 port available?


Thanks

    Hi,

    I'm note sure you can achieve that data speed over UART/RS232.

    But you can use UART interface b/w two EVM/device to exchange data.

    You need to connect both of the device over wire (both UART lines) and then in SW you need to have UART configured read or write data. Here USB interface is not used.

    Refer mmWave SDK mmw demo for AWR1843AOP and xWR1443 device, where it uses UART to send or receive CLI commands. You need to connect this UART lines with each other and modify the UART handling part in both application.

    On both EVM/boards you  need to check the schematic of the points for UART, may need to connect some resisters to bring those lines to EVM header.
