HI boys, please, can you help me? To this day I use optocoupler PC817 to interfacing atmel or pic input with other devices - switches, relay contacts, etc. Now I make redesign of pcb and need smaller size. pc817 is very big. I need some another circuit such as transistor, zener diodes etc. Connection will be same - switch NO NC, or contact of
Hi. I do ZCD for AC Power lines. I read application note of Microchip AN521. This application note explain for interfacing AC Power lines directely connect with Microchip I/O Pin. My Problem is they told Phase connect with I/O pin of microchip but they cannot mention what about connection nutral. Is it required to connection of Nutral .?
Your post says that this is a "Sensor interfacing circuit" but I actually don't know where is your sensor !!! If I'm correct then I guess the sinusoidal function generator represents the sensor, that's why you mentioned it's voltage changes from 0.6V to 40V. The only thing I couldn't figure is how may the sensor change with a frequency of 100Hz?
give me the idea about isolation circuit i mean any means to isolate the main circuit while interfacing with power line normally for power line communication to transmit/receive data isolation circuit may be any form of transformer
I have pnp type proximity sensor with output current 200mA & want to interface it with mcu at89c51 please help me as I am confused about interfacing current output to mcu Can we use relay & optocoupler if yes please send circuit or suggest any other possible way Thanks in advance bye
i think that you may have a problem doing the interfacing without some kind of driver that you proably cant get source for

Hi all, i'd like to interface to either an ethernet PCMCIA card (standard or wireless), using a standard ?controller (like M16C, or that kind), using an EPLD to do all the interfacing job. Anybody having already done this,or any information on how to realise PCMCIA interface would help. For another project, I would also like to make my own

I wrote this ke**il c c0de for interfacing 8o51 to @D7715 ,a 16 bit sigm@ delt@ c0nverter from anal0g devices. But It works good for several hours and I can get data from ADC,But suddenly the ADC does not give correct data it only gives 0x0000 code on any analog input. I do not know what is the problem ? Is it noise? PCB layout? Lost sequence
Hi, Does anybody knows where can I find subroutines for interfacing a CompactFlash to a 89C51 microcontroller? Thanx.
Hi friends, I have two doubts regarding 1.interfacing external eeprom interfacing. If ext.eeprom (for eg AT24c04) is directly connected to atmega16 with correct 10k pull up resistor, I am not getting the proper channel set for data flow and hence data transfer doesn't takes place but when i changed volatge from Vcc(5v) to 3.3v it worked
