ADS1256EVM-PDK: Inquiry

Part Number: ADS1256EVM-PDK
Other Parts Discussed in Thread: ADCPRO, ADS1256

Hi,

Good day.

Our customer is using the ADS1256EVM-PDK and they have the following observations and question.

"I've purchased an ADS1256evm-pdk for evaluation of the mentioned ADC
And I'm trying to use the ADCPro software, but it is *very* buggy - do you have any information/resources on software that I can use to evaluate the EVM card

Typically errors in the DLLs / USB drivers



that's one of the messages. The software can sometimes not be closed and I need to reboot the computer.


This one is especially tricky...



And this one frequently occurs.

Quite often memory issues, do you have perhaps some issues with memory leakage and garbage collect in the code? After som time I am not able to capture only 100-sample sequences

I do see from the forums that I am not the only one with issues with the software. Is there a way to bypass the ADCPro and use e.g. python or so?

In general, is there a way to store the default settings, since I have to restart every five minutes or so, it takes some time to remember to program the chip with the settings. Like sending the entire register map or so?"

We appreciate your inputs and help on this matter. Thank you.


Regards,

Cedrick

  • Hi Cedrick,

    We are in the process of moving some of these older EVMs off of ADCPro to a newer platform. At the moment, we don't have an alternative software solution for the ADS1256EVM. There are some example code projects out there that the customer might be able to reference if they are open to trying to connect the EVM to an external MCU:

    http://e2e.ti.com/support/data_converters/precision_data_converters/f/73/p/338399/1182307.aspx#1182307 (example code for the MSP430)

    github.com/.../ADS12xx-Library (third-party project on GitHub with example code for Arduino)

    Regarding the ADCPro error messages

    • I might suggest trying to reinstall ADCPro and the ADS1256EVM-PDK plugin to see if that helps resolve the issue. I have seen LabVIEW applications get corrupted and show similar messages at times.

    • Also, it looks like there is an issue with ADCPro not being able to read the EEPROM on the ADS1256EVM. As a workaround to this problem, I would suggest opening up the C:\Program Files (x86)\ADCPro\plugins\evm\ADS1256\adcpro_evm.ini file and changing "EEPROMVerify=TRUE" to "EEPROMVerify=FALSE".

    Best regards,
    Chris
