ADS7953EVM-PDK: Sample embedded C code to setup and communicate with the ADS7953EVM over SPI

Part Number: ADS7953EVM-PDK
Other Parts Discussed in Thread: ADS7953

Do you have any Aample/application Embedded C code to setup and communicate with the ADS7953EVM?

I am using RH850 micro-controller and will interface with ADS7953 Ext ADC to read high side voltage and temperature values over SPI. So looking for Sample C code which will run on RH850 micro to read this Ext ADC.

Thanks,

Pramod

    Hello,

    Unfortuently we do not have sample code. There is a software available to support the evaluation of the device with our EVM in the EVM landing Page

    When creating code to communicate to the ADC, it is important to follow the timing diagrams for the device given in the datasheet. An easy way to make sure your communication is correct is by probing the digital lines, CS, SDI, SDO, Clock, in a scope shot.  I find this easier to see the issue than to try to find the error in a long code.

    Also, another way to make sure your communication is correct is by writting to the registares, and then reading them. This will ensure that you are infact registering the device correctly.

    Once you have this down flawlessly you can begin adding any spepficic modes your applications calls for.

    Regards
