ADS127L01EVM: ADS127L01

Part Number: ADS127L01EVM
Other Parts Discussed in Thread: ADS127L01,

Hi Sir,

I am trying to use ADS127L01 in our own designed board. In order to develop our own software we need support from you how to read the data from ADS127L01 or if you provide the ADS127L01 EVM source code it will be helpful for us. We can refer that code and we will try to develop our own accordingly.

Thanking you sir,

Regards,

Teja

  • Hello Teja,

    Welcome to our forum!

    The source code for the ADS127L01EVM is currently not available. If you have any specific questions about the interface, please let us know and we can help clarify them.

  • Hi Ryan

    We are trying to read the data from ads17l01 by sending these commands reset(0x06),start(0x08),rdata(0x1 2).Along with that we are setting the baurd rate as 4.4mhz,4 bytes to transfer,spi mode 1.we are unable to get the data. Is there any source code which is similar to this ADS127L01.

    Thanks,

    Regards

  • Hi Teja,

    It is not necessary to send the RDATA command to read the data. When /DRDY goes low, you simply need to bring /CS low to activate the interface and send SCLKs to the device. The data will be clocked out on DOUT automatically. RDATA is only needed to reload the output shift register with the most recent conversion on-demand (i.e. to read the same data multiple times).

    Can you please share a schematic of the connections to the ADS127L01?

    After sending RESET and START, you should see /DRDY pulse at the set data rate. If not, then the device has not initialized correctly. Can you probe this pin with an oscilloscope?

    Best Regards,
