Hi Leo , Your choice is very good. It is a very good idea to replace PLC' with FPGA's. Because you have benifits from both aspects . i.e. in cost wise and also in accuracy wise. If we consider the cost , by using a single FPGA , you can replace more than ten PLC units. ( Normal PLC has 8 Inputs and ...

This is a good programme

Hi Friend , You can easily do this by one MCU pin , if your MCU have some ADC pins. then you have to make some hardware using voltage deviding resistors , which apply unique voltage on a ADC pin . when pressing each of the numeric switches ( 0 to 9 ). Then you have to decode the voltage values into ...

Hi Leo ,

This is true , when using PIC Microcontrollers in Industrial enviroments , I noticed , that some times PIC microcontrolers get restart. But
I have not face such problem with Atmel so far , for the same microcontroller power supply hardware.

Hi Friend , There are lots of compilers for programming PIC microcontrollers. Some compilers like Mikro C and PIC Basic Pro contain lots of libraries , for easily interfacing the pheripherals of the microcontrollers. So using this type of compilers , you can minimize the development time as you do n...

Hi Friend , In a enviroment like , tea factory , there are lots of elecromagnetic interfearances could occure , bacause of high power Motors. So this could badly effect to microcontrollers RAM and could lead to change the data in the RAM. So if your program have initializing routines , which set som...

if you write some programe and compile it with suitable compiler , a file which have the extention of .hex will generate in the folder , which contain your project. you have to download this .hex file to the particular microcontroller , by using some flash programmer. There are lots of Circuits for ...

Digital signal processors are also some kind of microcontrollers , but they have optimized to handle digital processing algorithms. As a example digital signal processing algorithms like Fourier Transform contain lots of floating point calculations. So most of the Digital Signal Processors contain ,...

Hi , Can you try with some bit low frequency oscilator like 4 MHz . As your application is not very much speed critical , there is no need to go for high frequency oscilator. 4 MHz is very much sufficient for you application. When you choose an oscilator , you must check the maximum speed , that you...
