4-2. Installation Guide
4-2.1 GP IO
When the appl ication is executed, it wil l display GPIO inform ation i n the GP IO IN FORMATION group box.
It displays the number of i nput pi ns and output pi ns. You can click the radio button to choose to rest
either the single pi n function or multipl e pin functions.
 Test Read Single Input Pi n
- Click the radio button-Single-P in.
- Key in the pi n number to read the value of the input pin. The Pin number starts from
“0”.
- Click the READ GPIO DATA button and the status of the GPIO pin will be displayed in
(R/W) Result field.
 Test Read Mul ti ple Input Pi ns
- Click the radio button-Multiple-Pins.
- Key in the pin number from “0x01” to “0x0 F” to re ad the value of the input pin. The
pin
numbers are ordered bitwise, i.e. bit 0 stands for GPIO 0, bit 1 stands for GP IO 1, etc.
For example, if you want to read pin 0, 1 and 3, t he pin numbers should be “0 x0B”.
- Click READ GPIO DATA button and the statuses of the GP IO pins wi ll be displayed in
(R/W)
Result field.
