6.3.5 LEDs
(CR)
The development board has 8 LEDs for digital output. To enable the LEDs, the GPIO_OUT (SW?) switch
should be set to LED_ON. The LEDs are turned on when the related GPIO pins of the ZE20S are high.
6.3.6
Button Switches (SW)
The development board has 8 button switches for digital input. The switches can be configured as active
high or active low with the GPIO_IN (SW?) switch.
6.3.7 Variable
Resistors
(VR)
There are two variable resistors for analog inputs on the development board. The analog inputs can be
read with the GPIO_? and GPIO_?. To enable the variable resistors, the ADC_0 and ADC_1 switches
should be placed to VR_? and VR_?.
6.3.8 Temperature
Sensor
The GPIO_? of the ZE20S is routed to the temperature sensor. The relationship between temperature
and analog input is as follows:
Temperature(
°
C) ={ Volt(mV) -600(mV)} * 0.1(
℃
/mV)
6.3.9 Light
Sensor
The GPIO_? of the ZE20S is routed to the light sensor. Approximately, the relationship between
illumination and analog input is as follows:
Illumination(Lux) = Volt(mV) * 0.25(Lux/mV)
