It is perfectly cool.. I Will Give a clear documentation about the project !! Since I am into initial planning Ideas may change as per the forum suggestions! Any how I will try to give a clear picture about my application requirement..

This news is very comforting..To be honest...
Yes It is not a Single Direction UART.. For Debugging purpose We have moved with duplex communication! May We can use in future

Separate Power Supply used to Power Up the Relays. We need to just pass the signals via Opto-couplers. So no connections in between relay circuits and this...
Hi.. I am really a lucky person to hear your 45 years R&D history! Too many things are very new for me! I will understand all and I come back if I have any other questions!!
Do you mean, You have placed across the Common and NO(Relay outputs) or across the relay's Coil?? Pullup resistor is bit...
My actual plan is to use 6 wires. 4 for RS422 (A,B,Y,Z) and 2 wires used to carry the power supply for receiver(Relay side). Current consumption is very less about 200mA.. Power supply is used to power up the Logical ICs only( 15V --> 5V convertor (LM2576 IC used)
5 Metres of 6 Core Shielded...
I really thankful for giving extra knowledge about the 74HC series drivers! Sure I will add 100E Resistor in series..

I have to thank all the suggestions from you! I have changed my mind set to go with the RS-485 / RS422.
Hi KlausST,
I would like to thank that you have studied my question from top to Bottom. Here I would like to give some more details ypou needed
Here is the link of the Data sheet -CD4094.
It is One way communication! Microcontroller sends data and it will not receive / wait for any...
Hello Everyone!
I have a Microcontroller Board to control some relays(Around 80 - 120 Numbers) with the help of CD4094 . Relay driver board is separate and it is 5 Meter in distance from the Microcontroller Board..
Now I have to send data to Shift registers-CD4094 which are 5 meters away...
I mean there should not be any rendering delay! Images should be displayed with in few milli seconds,Do not display slowly
Files size - For examble 960 Pixels (Height) x 1536 Pixels (Width)
Flexible Memory Control (FMC) found in STM32 microcontrollers
Well Understood. As I have mentioned...
Hello Everyone,
I have to design a Hardware to display image files on 7" Inch TFT display. Image(.BMP & JPEG) are stored in USB drive(Pen drive) as well as in Micro SD Card in a . I never experinced with multimedia/ Graphics application and I have no idea about the selection of MCU/MPC...
* give useful isolation (clearance) at the optocouplers
> You mean Pad to copper Clearance. 0.6mm Already provided
Hello Klaus,
Thanks for your guidance.
Hello Betwixt,
We are sure We have used 74HC595D( Nexperia Make). I am very eager to know the errors in the PCB board layout to rectify! I have assumed that just routing the Air wire will give the expected result! But I am not aware of trace impedance! Please give guidance!
We have attached...
Hello Experts,
I am having a project which will show some Pictures(.BMP files and .PNG) on the 3.2" TFT Display. Every display will have a MicroSD Card Slot. Our concern is We should not use that port. Instead, We have a MicroCard in our application board connected with Dedicated hardware...
Hello KlausST,
Thanks for your valuable reply! For your information, I have used 74HC595D( Nexperia Make) in my PCB. As per your input, I have changed the Power Supply from 5V to 3.3VDC by using LM1117-3.3V LDO.
The problem remains the same, as stated earlier Everything works fine Most of the...
Dear Everyone,
Greetings! I have designed a PCB for 8 channel 24V solenoids controlling Purpose with 74HC595! The Schematic is Very simple it is just one 74HC595 IC with 8 IRF540 MOSFETs! 74HC595 ICs Control lines are from another PCB ( Latch,OE,CLOCK,DATA @ 3.3V Logic). The cable is nearly...
Yes this should be corrected from my side!! Thank you!

Whenever We touch the 13th pin(R1IN) of Max3232CPE+ with piece of single wire it is starting to give any data. It is not too lengthy, but it is about 1 or 2 bytes. Here software start to misbehaving from the expected ! Actually...
