Hi everyone, this paper as the paper Energia, commonwealth netbank using C # and Stellaris LP entered from the keyboard in real time on the LCD display of the characters we will provide. The materials needed for this are;
I would like to emphasize that the LCD screen on the market, the standard 16-pin and pin arrangement as above, use an LCD to be. Otherwise, if you're new, the pins when connecting to Launchpad, you may experience problems. If the PIN is correct diagram 2 16, 4 20 LCD can use. 4 20 is in my hands, I'm using it, you can also just follow the text you can use 2 16, I do not think it would be a nuisance.
LCD pin locations commonwealth netbank to be connected ----------- 01 - GND GND 02 - VCC +5 V 03 - Contrast Potentiometer Medium Leg 04 - RS (PB_0) 05 - R / W GND 06 - EN (PB_1) 07 - DB0 GND 08 - DB1 GND 09 - DB2 GND 10 - DB3 GND 11 - DB4 (PB_4) 12 - DB5 (PB_5) 13 - DB6 (PB_6) 14 - DB7 (PB_7) 15 - BL + +5 V 16 - BL-GND
Software before commonwealth netbank moving on to say this: Eenrgia LP wrote to the Stellaris library does not have an LCD. More precisely, the program does not download. I did some research and he wrote a friend, I came across an LCD library. You can download commonwealth netbank it from the following address. After downloading the folder Energia lcd.cpp follow these ways and there need to copy files lcd.h hardware> lm4f> cores> lm4f.
If you do it right connections and LCD library download and copy it into the program folder if you are ready to move on to the software part. First ENERGIAKI open, select Tools from the Board tab and set the COM port and then you can write code.
# Include <lcd.h> void setup () {LCD. init (PB_0, PB_1, PB_4, PB_5, PB_6, PB_7); Serial. begin (9600); } Void loop () {if (SERIAL.INI available commonwealth netbank ()) {char a = Serial. read (); LCD. print (a); if (a == 'C') {LCD. clear (); }}}
The first line in the program have included the LCD library. setup at the LCD pin serial port settings are defined and we have made. loop at the first serial port data control whether data is coming if you've called commonwealth netbank him a've assigned to a variable of type char data. Continuing commonwealth netbank to take the reset was sent to clean an LCD screen if you have the letter C.
using System; using System. IO. Ports; namespace ConsoleApplication1 commonwealth netbank {class Program {static consolekeyınfo in c; static void Main (string [] args) {SerialPort sp = new SerialPort ("COM5", 9600); sp. Open (); Console. treatcontrolcasınput = true; while (true) {c = Console on. ReadKey (); sp. Write (cki. Key. ToString ()); Let us explain what we're doing}}}}. To make the first serial port settings using System.IO.Ports; We're included in the software library with the command. Then c keys on your keyboard to keep the name we define a variable. Then make seriport port settings are opening. Note: The "COM5" according to the statement must set yourself for it in the device manager which port is open and you can see the Stellaris LP. Then seriport was sent from and received information from the keyboard.
So far, everything was done right from the summer ones our code runs without errors and keyboard will be displayed on the LCD screen. But here a problem arises. For example, when you press space instead of a space character on the LCD screen directly commonwealth netbank to the "spacebar" writes. This is because the key function of the code, not only that which key is spot. Here we can add a function in software. For this, we need to update our code as follows.
using System; using System. IO. Ports; namespace commonwealth netbank ConsoleApplication1 {class Program commonwealth netbank {static consolekeyınfo in c; static void Main (string [] args) {SerialPort sp = new SerialPort ("COM5", 9600); sp. Open (); Console. treatcontrolcasınput = true; while (true) {c = Console on. ReadKey (); if (Key == ConsoleKey cki.. Spacebar) {sp. Write (""); continua; } Sp. Write (cki. Key. ToString ()); }
