Part Number: ADS124S08EVM

Tool/software:

Hi,

I am using the ADS124S08EVM to measured a voltage with single ended on AIN0.When I configure the board under continuous mode, it runs well.

But when configure it under single shot mode, the GUI seems get blocked and no response. Could you help to check am I configure it right and how to solve it?

    Hi Matthew Chen,

    It is always best to check the digital communication on the ADC to see what is going on. I think I have recommended this to you already.

    I copied your settings and was able to get data, see below. Are you using the ADS124S08EVM as is? Like the only thing you are doing to get from the first image (continuous conversion mode) to the second image (single shot mode) is changing the MODE bit in the DATARATE register?

    Hi Bryan,

    Currently i am limited to install the software for logic analyzer, already to ask it to approve that.

    The only difference is the mode i set in the GUI. While i cannot get the result in single shot mode. i will try your configuration and obverse the communication by  oscilloscope.
