Pin connect Block and Register Description of LPC214X microcontroller

Pin Connect Block:

The purpose of the Pin connect block is to configure the microcontroller pins to the desired functions. The pin connect block allows selected pins of the microcontroller to have more than one function. Configuration registers control the multiplexers to allow connection between the pin and the on chip peripherals.

Peripherals should be connected to the appropriate pins prior to being activated, and prior to any related interrupt(s) being enabled. Activity of any enabled peripheral function that is not mapped to a related pin should be considered undefined.

Register Description:

The Pin Control Module contains 3 registers-
  1. PINSEL0 :- It selects Pin function register 0 and can read/write operations.
  2. PINSEL1 :- It selects Pin function register 1 and can read/write operations.
  3. PINSEL2 :- It selects Pin function register 2 and can read/write operations.

Comparison Chart Between 8051, 8052, 8031and 8751

8051 is a popular 8-bit microcontroller and has been used in many applications since Intel introduced it. Many 8051 architecture are produced by Triscend, Intel, Atmel, Philips, Infineon (Siemens), ISSI, and Max Corp. Today, 8051 microcontrollers may not be popular but, the 8051 architecture is still popular and employed in thousands of embedded applications. This 8-bit architecture has been different segments such as 8052, 8051, 8751 and 8031 . 8052 is the super-set of 8051 and 8031 is the memory-less microcontroller hence, it has interfaced with external ROM. Whereas, 8751 chip has only 4Kbytes of on chip UV-EPROM. Everyone knows about the general 40-pin microcontroller i.e. 8051 introduced by Intel in 1980s and consists of serial communication pins, Timer, Interrupts, RAM, ROM. It has 4 ports and each port has 8 pins, total 32 pins and other 8 pins for other purposes. 8052 is the super-set of 8051 that consists of 8K bytes of internal RAM (4K in 8051), 256 by...

Buzzer interface with 8051 microcontroller

Buzzer  is a electronic device that converts the electronic signal into buzzing noise, that is applied to it. It can be used as electronic bell or as quiz buzzer in many applications around us. Here, i world like to discuss the interfacing of a small buzzer with 8051 microcontroller and how different projects can be constructed. Buzzer Interfacing: This project shows the interface with AT89S52 microcontroller to a buzzer. When a push button is pressed, the buzzer will get ON and OFF ( number of times set in the code ) and then stops. Circuit Diagram: - The port P1 of the microcontroller is connected to buzzer. This type of connection is possible, if the current requirements of the buzzer is not more than 20mA. The output is in current source mode so that buzzer will turn ON when the output of the port is logic LOW. Switch is connected to port P3 which remains at logic HIGH by pull up resistor.  Code: #include "REG52.h" #define buz P1 sbit SW=P3^0; long i...

How to Switch OFF Citizen Calculator

You might be confused on seeing no OFF button on your calculator. Actually, these are general calculator available at low cost in the market. They process simple calculations like division, subtraction, Addition, Multiplication. But, how will you OFF that calculator having no option on them. There is always a trick which OFF them. It depends on the company calculator and their series to which they belong. I can tell you about Citizen Calculator CT-500 (as you can see in the image), how can you switch OFF it and can save battery too. If you leave calculator idle for 6-7 minutes, it will goes OFF automatically. My calculator goes OFF in 6.50 minutes from the point of leaving it idle. But, this is not the power saving trick for these types of calculator having not much backup battery. To save the power of your normal calculator, here is the trick to switch OFF it. Press ' /(divide sign)', 'x(multiply sign)', '%(percentage sign)', 'autoreplay option(...
