Bluetooth - µC - LCD Interface

Bluetooth - µC - LCD Interfacing

This Uncomplicated leisure time App strictly works as an interface between bluetooth module - microcontroller - LCD built merely for practice & learning purpose to display characters on LCD screen of the Developing Board (ARM based or otherwise) through an android app. For basic knowledge, one can also run other peripherals on the Developing Board via LCD commands (in the form of normal Characters) sent via App. Configure appropriate Pinsels when a particular character is displayed. It can also be used to pair/unpair BT devices.

The stream of characters can be received through UART which obviously needs to be coded. Check the baud rate for the same. Make sure the receiving loop for array of characters is terminated by '#'.

For KEIL, e.g.

do

{

//Run the loop to receive the characters saving in the receiving Register through UART

ch[i]=Receive();

}

while(ch[i++]!='#'); //terminated with '#', display characters on the LCD

i--;

ch[i]='\0';

//Display on LCD.

while(*stringChars!='\0')

DisplayonLCD(*stringChars++); //Pass Chars on 0x80

So, just an uncomplicated leisure time App to play around with ARM based Developing Board :)
