7.7 Interface Board and ADS1100
In the “Interface Board and ADS1100” section, in the Main Window, click on “Board Settings”. A pop-up
window will appear as in Figure 23. This pop-up window provides configuration control of the ADS1100 and
the Port Expander, PCF8574A.

Figure 23: “ADS1100 and PCF8574A Status” Window
In the pop-up window the bits under “EVM (PCF8574A)” will toggle when single-clicked. Table 6 describes the
use of each of these bits.
If the “Calibrate ADS1100” Button is pushed it will short the two inputs of the ADS1100 together and compute
the offset error. All ADS1100 readings which follow will be calibrated to account for this offset error. In
addition measure the voltage Vs on the PGA309 PC Interface Board with an accurate meter and enter this
voltage in the “Supply Vcc (V)” box in the Main Window or enter this voltage into the “Vs=” box in the pop-up
window. After these two ADS1100 calibration steps are complete the ADS1100 is fully calibrated for both gain
and offset errors. Each time the “Calibrate ADS1100” Button is pushed a new ADS1100 offset calibration is
performed and the subsequent readings will use the latest calibration numbers.
If the “Read ADS1100” button is pushed a single conversion will be performed in the ADS1100. The reading
will be updated in both the Main Window and in the pop-up window. If the box labeled “Read ADS1100
Continuously” is checked then both the pop-up window and Main Window ADS1100 readings will be updated
about every 2 seconds depending upon the operating system conditions.
The “ADS Output Register” section in the pop-up window is a read-only bit readout of the latest ADS1110
conversion.
The “ADS1100 Configuration Status Register” bits allow for custom configuration of the ADS1100. These bits
are toggled by a one-click method in the corresponding box. The default setting is 0x8C. This configures the
ADS1100 for Continuous Conversion Mode, Internal PGA=x1, and 8 samples per second data rate. If these
settings are changed they can be returned to the initial power-up settings by pushing the “Gen Call Reset” in
the pop-up window. If the Vcc voltage on the PGA309 PC Interface Board is changed then the ADS1100 will
need to be re-calibrated for gain and offset (this assumes Vcc will become the Vs for the PGA309 Sensor
Interface Board). For further ADS1100 details consult the ADS1100 data sheet.
