Gpio Control Panel - DEICO ONYX DE4001 User Manual

GPIO Control Panel

When user selects an operation mode that configures pins as GPIO, GPIO display will appear.
Pins configured as GPIO are dependent on the selected mode. For example, if I²C/GPIO mode
is active, SPI pins (Pin #9, #8, #7 and #5) are configured as GPIO.
Figure 26: I²C/GPIO mode
Figure 27: GPIO control panel
When GPIO mode is selected, all pins are configured as GPIO pins. Figure 27 shows the
configured GPIO pins in this mode.
In the GPIO control panel, there are two information fields, GPIO numbers and pin numbers.
Pin numbers specify the position of the physical pin on the target bus connector.
Four fields are editable in the GPIO control panel, which are directions, pull-up mode, output
value and the read value. Each field can be set exclusively for a pin.
