TIDA-00550: Software Files

Part Number: TIDA-00550
Other Parts Discussed in Thread: ADS1262

Hello,

I am looking for any software files or sample code available for the TIDA-00550 reference design.

Or if not, is there more specific information on what the various registers of the ADS1262 are set to for each measurement option?

Thanks for any help available,

Caleb

    Hi Caleb,
    I apologize for responding you late.
    I'm working on to see whether source code is available or not.
    I hope our engineer gives you answer soon.

    Regards,
    Yuki

    Hi Caleb,

    I apologize for the delayed response.

    Unfortunately, the test software is not available, but find below the settings for each test mode. After the software reset and the assignment of the GPIOs (to control the HC595) the following changes have been performed to the ADS1262 default settings (some of the parameter indicated below might be already default):

    Mode I (volt):
    - input channel: AIN0, AIN7
    - gain: 1V/V
    - in addition see table 7 in user's guide for filter+datarate settings

    Mode II (milliVolt):
    - input channel: AIN4, AIN6
    - datarate=20SPS, SINC4
    - in addition see table 9 in user's guide for gain settings

    Mode III (mA):
    - input channel: AIN8, AIN9
    - datarate=20SPS
    - FIR
    - in addition see table 10 in user's guide for gain settings

    Mode IV (loop):
    - input channel: AIN8, AIN9
    - gain: 4V/V
    - datarate=20SPS, FIR

    Mode V (thermocouple)
    - input channel: AIN4, AIN6
    - gain: 32V/V
    - vbias on
    - datarate=2.5SPS

    Mode VI (RTD)
    - input channel: AIN4, AIN6
    - ext reference: AIN2/3
    - IDAC1: 250uA
    - if RTD 3wire: IDAC2: 250uA
    - gain: 8V/V
    - FIR
    - datarate=2.5SPS

    Best regards,
    Lars
