ADS7142: ADS7142

Part Number: ADS7142

Chip is powered on, use under the default Settings, sent directly read data command, can receive data, but continuous read data is 0 analog input channel, continuous reading shown on the manual will take turns to read two channels of conversion data, check the manual again after the found on electricity is only 0 channel in collecting data, so the output is always 0 channel data, through writing register command to change its Settings, set it to two channels to collect data, continuous read data have become the FFF, close not to 0 channel data.

What should this configuration flow look like and how do you make it so that the conversion data for both channels can be read out as a continuous read?

  • Hello, 

    I suggest using the EM to help develop the firmware for this device. the EVM GUI has the ability to export register address and content based on the configurations in the GUI. This means that you can configure the device on the EVM through the user friendly GUI how you want it, and then export the register content to get that configuration. 

    In manual mode, you should be able to read back data. In Autonomous mode, you will not be able to read data, this mode only output an Alert signal. 

    Looking at the datasheet, I suggest focusing on the two figures below.
