Difference between AVR and ARM
A microcontroller is a small processing device which is primarily designed to perform specific functions within a large system. For example, a microcontroller is used in an air conditioner to automatically control and adjust the temperature of a room. The main parts that a microcontroller has are: central processing unit (CPU), memory unit, and I/O interfaces. All these components of the microcontroller are formed on a single chip. A microcontroller can be programmed using various programming languages like C language, assembly language, etc. to perform a specific function. Microcontrollers are widely used in a variety of electronic devices, such as ...

Read MoreBooks to read on networking and microcontrollers
Networking and microcontrollers have become ubiquitous in modern world, with demand for connected devices and smart homes on rise. If you’re looking to expand your knowledge on these topics, there are a plethora of books that can help you gain a better understanding of networking and microcontrollers. In this article, we’ll explore some of best books to read on networking and microcontrollers, along with their examples and sub-headings. "TCP/IP Illustrated, Volume 1: Protocols" by W. Richard Stevens TCP/IP Illustrated is a comprehensive guide to TCP/IP protocol suite, which is foundation of internet. This book covers all aspects of TCP/IP protocol, ...
Read MoreDifference between CALL and JUMP instructions
A CALL instruction is used to call a subroutine, while a JUMP instruction updates the program counter value and makes it point to another location inside the program. Read this article to learn more about CALL and JUMP instructions and how they are different from each other. What is a CALL Instruction? A CALL instruction is utilized to call a sub-routine. Using a CALL instruction, the program control is transferred to a location in memory that is not a part of the main program. A CALL instruction necessarily requires the initialization of a Stack Pointer (SP). It is basically ...
Read MoreDifferences Between a PLC and an RTU
You may have heard of Programmable Logic Controllers (PLCs) and Remote Terminal Units (RTUs), but what do these devices actually do? And more importantly, which one do you need for your business? PLCs are used to control machines by reading input signals and executing pre-determined programs in order to achieve a specific output. RTUs, on the other hand, are used to collect data from machines and send it back to a central location for analysis. Depending on your needs and level of complexity, there is an automation device that can provide you with complete control over your operations while keeping ...
Read MoreAdvantage of multiple chip select lines
Let’s consider that the EPROMs we have are having the starting addresses as 4000H, 4400H, …, 5C00H. 4000H in binary is 0 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0. In such a case, the 74138 has to be selected for the condition A15 A14 A13 = 0 1 0. This can be achieved by the connection shown in below figure which uses two invert gates.The procedure of selecting the chip74138 is denoted by the addresses A15 A14 A13 = 0 1 0 which can be implemented by any gates. We have taken ...
Read MoreGeneration of .HEX file using a linker
The file MULT.ASM which is created by using an editor is simply a text file. We cannot execute this file directly. At first we have to assemble the file, and then we have to link it. The step of assembly the translation of the program of assembly language to machine code requires the generation of a .OBJ file.Now a .HEX file is generated by using a linker. We have seen previously that how the naming of the input and output file is done.Input filenameThe source name of the file must be responded by the user. In the given example the ...
Read More8085 Program for subtraction of multi-Byte BCD numbers
Now let us see a program of Intel 8085 Microprocessor. In this program we will see how to subtract multi-Byte BCD numbers.Problem StatementWrite 8085 Assembly language program to subtract two multi-Byte BCD numbers.DiscussionThe numbers are stored into memory, and one additional information is stored. It will show us the Byte count of the multi-Byte BCD number. Here we are choosing 3-Byte BCD numbers. They are stored at location 8001H to 8003H, and another number is stored at location 8004H to 8006H. The location 8000H is holding the Byte count. In this case the Byte count is 03H.For the subtraction we ...
Read MoreLight Emitting Diodes (LEDs)\\n
Light can be obtained from various sources like candles, lamp and sunrays etc. Light bulb had invented by Thomas Edison in 1879. An electric current is passed through a filament inside bulb, it gets heated up and emits light when sufficient current is passed through the filament. That means it converts electrical energy into heat energy in the bulb. Where in Light Emitting Diodes (LED), electronic electrical energy can directly converted into light energy.Light is a energy which is released by atoms. Particles of light are photons which have no mass. Atoms are basic building blocks which are made of small ...
Read MorePin diagram of 8212
We find 8212 available in nowadays as a package chip which is dual inline having 24 pins total. We find its functional pin diagram below.Fig: Pin diagram of 8212 functionalFig: Pin diagram of 8212Voltage of + 5 V is required for it to work based on the supply which is DC. The latch which is 8 bit in 8212 receives the information which is present on the eight data inputs ranging from DI7 to D10. The condition which helps in information latching is present on DI7 to DI0 depends on the state of logic of the pin which is of ...
