Could you provide the driver demo code for ADS7039 auto-sequence mode?

I can only find the manual mode demo code.

    Hi Yan,

    Unfortunately we don't have anything at this moment to showcase the auto-sequence mode. Is there anything specific you would like to accomplish with it? Maybe I can help you in coming up with a command sequence for it.

    Regards,
    Joel

    Hi Joel

    thanks for your reply

    my sequence of commands:

    1. Reset

    2. Channel ID append enable

    3. choose auto-sequence mode 

    4. Channels 0, 1 and 6 activated for auto-sequencing

    5. Start Sequencer

    The SPI rate is 2M, transmit and receive FIFO are enable.

    After these configuration steps ,  I can not receive the sampling result. Is there any missing step? Do I need to configure the sampling rate by OSC_SEL and CLK_DIV?

    In auto-sequence mode , set SEQ_START to 1 for one time and it will trigger the continuous sampling without the rising edge of CS yes?

    Hi Yan,

    Can you clarify if you are asking about ADS7038-Q1 or ADS7039-Q1? From your description, it seems like you are referring to ADS7038-Q1. Am I correct? If so, I will delete this thread and ask for you to post a new thread under the relevant device.

    Regards,
    Joel
