Main >> CORTEX >> Sensors Overview |
| For ROBOTC CORTEX Sensor functions, check out the CORTEX Sensor Functions page! |
|
The VEX 2.0 Cortex is equipped with 20 sensor ports. There are 8 Analog Sensor Ports and 12 Digital Sensor Ports. Note that unlike the VEX - PIC microcontroller, all Analog sensors must be in Analog ports, while all Digital sensors must be in Digital ports. There are a variety of functions and variables used for configuring these ports and accessing their values. Configuring sensors can be complicated. ROBOTC has a built-in wizard that can be used to configure the VEX 2.0 Cortex sensors. The wizard contains a number of PC windows that allow you to set the following fields for the sensor:

Analog Sensors
| There are 5 main types of Analog Sensors for the VEX CORTEX: |
ReflectionThe Reflection sensor, also known as the Line Follower, returns values ranging between 0 and 4095. 0 is the lightest reading and 4095 is the darkest.
