May 18, 2014 Hi, I have interfaced AT25F1024 SPI-EEPROM with LPC2129. The code is to write a single byte of character in to the AT25F1024 & again read the same byte & display on the lcd. I know how to display on the lcd. But i don't know how to write & read a byte from AT251014. Apr 15, 2013 - INTERFACING LEDs TO ARM 7 CONTROLLER- (LPC2148 )Light. ComPROGRAM -1This program blinks the LEDs continuously with a small delay. By applying the code in the reverse order, the stepper motor can be. ARM7 LPC21xx processor is interfaced to the 2x16 LCD mpdule in 4-bit mode.
Keypad interface with ARM7 Microcontroller Keypads are the most commonly used input device in many embedded system since it possess simple design and also comes at affordable cost. This makes the concept of keypad interfacing with a Microcontroller very important. We are about to see the tutorial of keypad and lcd interfacing with the ARM7 Microcontroller ( LPC2124). The above design uses a 4×3 keypad to take input and a 16×2 LCD to display the input value fed by the keypad. If you are not familiar with LCD interfacing with ARM controller kindly go through this tutorial. POLLING: Keypad interfacing can be done with the Microcontroller by means polling and interrupts.
Since interrupts will not fit when interfacing large number of keys so polling becomes the ultimate choice. Polling is nothing but making the rows of the keypad as input and column as output or vice versa. In this method each row will be made low one at a time and the corresponding logic transition in column value will be monitored by the Microcontroller. So for example if key ‘5’ pressed at any moment the Microcontroller will realize this when row 2 and column 2 is low at same instant. Note that you can monitor either row or column with the Microcontroller for logic transition.
4×3 KEYPAD: The above diagram shows the construction of a simple keypad using push buttons. 
Whereas i have used a ready made 4×3 keypad in the above design, you can opt for any of it. You can also expand the keypad configuration by adding more switches to it.
CODE: The below code was built using Keil uVision 4 and built in such a way to scan the keypad and display the input values in the LCD connected to the Controller.
