What do they have in common?**</span> ---- The answer is computers controlling hardware. Making lights go on and off. Controlling motors, relays and other electronic components. Liberty Basic for windows makes programming simple but lacks the ability to directly control or interface with hardware (except the parallel port). To make hardware interface coding simpler a set of functions is required to facilitate the communication with external hardware. Because the arduino is the most widely used hobby micro controller in the world and has so much support it is the obvious choice to make a set of simple functions for LB users to take advantage of this great platform for there projects. The things covered in this article are limited to simple port I/O (Input and output). * <span style="line-height: 1.5;">Test if pin is high or low</span> ** <span style="line-height: 1.5;">Get input from buttons and other sensors connected to the arduino</span> * <span style="line-height: 1.5;">Set a pin high or low</span> ** <span style="line-height: 1.5;">Turn things on and off like lights, buzzers, motors, ect.</span> * PWM (Pulse width modulation) output ** Dim lights, Control servo motors, interface with variable speed motor controllers * PWM <span style="line-height: 1.5;">(Pulse width modulation) input</span> ** <span style="line-height: 1.5;">Get input from things like sliders and position information</span> ---- =Getting Started with the functions= ||~ Code ||~ Example Circuit || ||< ===-Initialization code=== <span style="line-height: 19.5px;">This code sets up the arrays that will be used to manage pin settings and values.</span> <span style="line-height: 19.5px;">Should be placed at start of program.</span> [[code]] dim ad.pinstatus(10,100) dim ad.pinSetting$(10,100) for x = 0 to 10 for y = 0 to 100 ad.pinSetting$(x,y) = "Un-Set" nexty nextynext x [[code]] ||< || ||< ===-Setting a pin Status=== To set a pin high or low you can call the following function. The com port must be specified as a number (To address com3 you would use 3) The pin must be a number of a pin present on the arduino. The value to send must be a 1 or 0 (1 = high, 0 = low) The return value will be a 1 if successful and 0 if not. [[code]] return.value = AD.Set(Com.port, Pin, Val.To.Send) [[code]] ||< [[image:Arduino as a slave 2.png]] || ||< ===-Pulling the input status of a pin=== This function will retrieve a 1 or 0 depending on what the status of a sensor connected to the arduino is. The com port must be specified as a number (To address com3 you would use 3) The pin must be a number of a pin present on the arduino. Will return a 1 or a 0 depending on if the input pin is pulled high or low. [[code]] return.value = AD.Get(Com.port.Selection, Pin.Selection) [[code]] ||< [[image:Arduino as a slave 3.png]] || ||< ===-Setting a PWM output=== PWM Will allow you to control a servo, dim a light, ect. The com port must be specified as a number (To address com3 you would use 3) The pin must be a number of a pin present on the arduino. The value must be a number between 0 and 254. [[code]] return.value = AD.PWM.Out(Com.port.Selection, Pin.Selection, Val.To.Send) [[code]] ||< || ||< ===-Pulling the PWM input status of a pin=== The com port must be specified as a number (To address com3 you would use 3) The pin must be a number of a pin present on the arduino. The return value will be number between 0 and 254. [[code]] return.value = AD.PWM.In(Com.port.Selection, Pin.Selection) [[code]] ||< || ||< ||< || ||< ===-Setting a servo output=== Will allow you to control a servo. The com port must be specified as a number (To address com3 you would use 3) The pin must be a number of a pin present on the arduino. The value must be a number between 0 and180 and will ruffly be180, the number of degrees the servo will rotate to. [[code]] return.value = AD.Servo(Com.port.Selection, Pin.Selection, Val.To.Send) [[code]] ||< [[image:Arduino as a slave 5.png]] || ||< ===-Managing Pin Settings=== There are 2 arrays that manage what a pin is set to (set, get, pwm.in, pwm.out, servo) and what the last value assigned to that pin was or retrieved from the device as an input pin. With these arrays to can both retrieve the current pin value and setting. You can also set the value and pin setting. In this way you can update the values and settings for a group of pins and apply those settings all at once with the [[code]] value.pin.was.set.to = ad.pinstatus(Com.port,Pin) Pin.Type.Setting$Pin)Pin.Type.Setting$ = <span style="font-family: arial,helvetica,sans-serif; line-height: 1.5;">ad.pinSetting$(Com.port, Pin)</span> [[code]] ||< || ||< ===-Set and retrieve all pin settings and values at once=== The AD.Update.All() function will use the 2 arrays that are defined at the start of the program and update the values of each pin based on the inputs from the arduino and also set the output values on the arduino device. This allows for all the pins of all the connected arduino devices to be updated to the values from the ad.pinstatus() array and the pin type setting from the ad.pinSetting$() array. [[code]] bla = AD.Update.All() [[code]] ||< || ||< ===-Closing your program gracefully closing all the com ports=== This function will close all the open com ports as a com port is kept open after any interaction with the arduino module. [[code]] AD.close.all.the.com.ports() [[code]] ||< || ||< ||< || ---- =The Arduino Code= To make liberty basic talk with an arduino they have to speak the same language. In this case a string is used andsendsent over to the device followed by a carriage return character CHR$(13) The only thing you really have to understand about the arduino code is that it must be download to the arduino board using the arduino IDE. This can be download from the following link. http://arduino.cc/en/Main/Software **Note:** This code isdonewritten inarduinosthe Arduino's special form of c and is not basic code.
