The primary language used to develop for NeTV is Lua. This language was chosen because it's both easy to work with and is very fast.
Contents
Motor control library API
There is a motor control API available. To import the library, run:
require("motor")
Digital I/O
motor.set_digital(v) - Sets the digital output pins to the value v. All pins are set at the same time.
Motor control
motor.set_type(m, t) - Sets the type of motor m to the type t. To switch to a servo, specify "s" for t. To switch to a motor, specify "m" for t. Note that you can only set channels 1 and 2 to servo.
motor.set_speed(m, v) - Sets the current speed of motor m to the speed v. The speed is specified from -255 to 255.
motor.set_angle(m, a) - Sets the angle of motor m to a degrees. The angle must be between 0 and 180.
Analog input
motor.get_adc(a) - Gets the current value from ADC a. There are 8 ADCs numbered 0-7. The return value is from 0 - 255.
Miscellaneous functions
netv.sleep(t) - Sleep for t seconds. t' is a Lua Number, and so may be non-integer, e.g. 0.5.
