Product Specs

2.9.1 Digital Inputs

Any of the 9 GPIOs may be configured as digital inputs. There are five different input configurations as

shown in Table 3-2.

Table 3-2: Input Pin Configurations

Input Pin Configuration

Description

DigitalInput

Configure as high impedance (floating)

DigitalInputPullDown

Configure with internal pull

down to GND

DigitalInputPullDownWeak

Configure with external pull

down (1 M

Ω) to GND

gitalInputPullUp

Configure with internal pull

up to VDD

DigitalInputPullUpWeak

Configure with external pull

up (1 M

Ω) to VDD

A GPIO digital input example is shown in Figure 3-10.

01 Define PinMode Pin0 As DigitalInputPullUp

02 Class InputPinTest()

3 Shared Event Pin0FallingEdge()

4 // pin0 has gone low, turn on LED for 100ms

5 LedGreen = True // Turn on LED

6 Thread.Sleep(100000) // Sleep for 100 ms

7 LedGreen = False // Turn off LED

8 End Event

9 End Class

2.9.2 Digital Outputs

Any of the 9 GPIOs may be configured as digital outputs. A GPIO digital output example is shown in

Figure 3-11.

01 Define PinMode Pin1 As DigitalOutput

02 Class OutputPinTest()

3 Shared Event TogglePin1() RaiseEvent Every 500 milliSeconds

4 // toggle Pin1 every 500 milliseconds

5 Pin1 = Not Pin1 // Toggle Pin1

6 End Event

7 End Class
