4.1.3 Inputs and Outputs
Figure 4. LEDs and buttons
nRF8002 has the following input signals:
•
The button SW1 is routed to signal IN1
•
The button SW2 is routed to IN2
In addition, nRF8002 has three digital outputs and a PWM output. The three digital output signals are
routed to three LEDs in the following way:
•
OUT1 is routed to the LED LD1
•
OUT2 is routed to the LED LD2
•
OUT3 is routed to the LED LD3
JP1, JP2, and JP3 disconnects the output LEDs LD1, LD2, and LD3 respectively. When using external
LEDs through either the I/O pin header or the motherboard, it’s a good idea to disconnect onboard LEDs
by removing these jumpers.
The PWM output is described in the following section.
