Figure 5-2: GPIO Counter Mechanism

Interrupt and Counter performance

1. Interrupt latency - notification to UM.

• Idle - 10 ms.

• While HTTP download session - 15 ms.

• While UDP download session - 20ms.

Note: For both HTTP and UDP, thread yielding must occur. See “GPIO Interrupt Latency” for

more information.

2. Counter frequency:

• Idle - 2 KHz.

• While HTTP download session - 500 Hz.

For additional GPIO information refer to “GPIO Lines”.

GPIO Classes

1. GpioInput - GPIO configuration as input, interrupt or counter.

Actions: read status, enable/disable interrupt/counter

2. GpioOutput - GPIO configuration as output.

Actions: write

3. GpioInterruptConfig - is container of interrupt GPIO.

Configuration: notification type, debounce type, and notifications listener.

Default configuration values:

a. Debounce: 40ms (Normal).

b. Notifications: both edges.

Note: Gpio interrupt performance are detailed in “GPIO Interrupt Latency”.

4. GpioCounterConfig - is container of counter GPIO.

Configuration: notification type, counter type, counter expiry, and notifications listener.

Default configuration values:

a. Debounce: disabled (Can not be changed).
