TDA3MV: How to use UART1 and UART2 simultaneously?

SDI

Part Number: TDA3MV

Tool/software:

Here is the translation of your question:

Hello, I am working with PROCESSOR_SDK_VISION_03_05_00_00. I am currently using UART2. I would like to use UART1 as well, and I am wondering where to enable UART1. From what I have found, it seems that UART is enabled in the System_uartInit() function. I would like to know if there is anything additional I need to do here. Also, if UART1 is enabled, I would like to know how to separately receive from UART1 and UART2 when executing GIO_read().

Thank you

Best Regards

    Hi,

    Can you tell me more about the background of this project? Is this an existing project or a new one? Also, what is the motivation for moving to UART1 so that we understand what we are trying to support? Is your platform board taking care of separate UART1 and UART2 ports?

    Thanks.

    Thank you for your response.
    We have been using UART2 to control the camera. This time, we are planning to additionally control the Zoom Lens using the UART1 signal.
    On the board we have developed, UART1 and UART2 ports are separated.

    OK, thanks for the info. Please follow the code for configuring UART2 in the SDK and the same for UART1. Make sure that no UART1 pins conflict with other uses on your platform. Note that you must handle any code changes and regressions and fix them; TI cannot support that.

    Thanks.
