9.1.3 GPIO Tab

The GPIO Tab (shown in Figure 27) allows control of the ADS1258 GPIO pins. Down the center of this

screen, the I/O Mode switches set whether each GPIO pin is an input or an output.

Figure 27. GPIO Controls

When selected as outputs, the Output buttons set the state of the GPIO pins; when pressed and lit, the

pin will be driven high; when unlit, the pin will be driven low.

If selected as inputs, the LED indicators next on the right hand side of the screen will display the state of

the pin (lit for HIGH and unlit for LOW). The state of the GPIO pins is sampled only when the Input button

is pressed—in other words, the display will only update when this pin is pressed.
