Canon MMC
Hi guys!!
I have a canon multimedia card and I want to read/write data from/to it,but I have no idea about it's pinout and how to connect it to atmega128 .I mean i can't fide any datasheet for it.Does anyone have any guidance for me.I should resist that unfortunately there is no other...
Hey everybody!
I am working with an Atmega2560 and want to read and write data from/to a serial flash memory anytime i need to.I have two questions:
1-Is it possible to use a MMC? if yes,please give me some guidance about how Atmega2560 interfaces a MMC?
2-What kind of serial flash memory i...

Hey guys!
I'm working with atmega128 which has 128k internal flash memory.This amount of memory is not enough for my code.How can I extend my memory to store the rest of my code in it.I mean does anybody have any sugestion?
Thanks so much for your help unaided!
You mean that I shouldn't be worry about the boot block in flash memory?!!
Can I easily work with CodeVision to program flash memory via Atmega128?
According to my searches it is not that easy to interface external flash memory!!!
Do you have any code which...
Hi everybody!
I want to use an external parellel flash memory to store my code in it.does anyone have the experience to write data in parallel flash memory with an Atmega128 and read it successfully? I have no idea how can i write the code!!!
help me Plzzzzzzzz...:cry:
1- It is because (R2/R1)=(R3/R4). In other words we have same voltage dividers, so we have same voltages at two input nodes of opamps.Note that it is not necessary to apply a DC voltage,it can be ac but equal at v1 & v2.
2- To find differential input impedance,we apply a signal source across the...
Wien bridge
thank u all. It helped a lot dear LvW!
But would it produce a sine wave anyway? even when there is a square error signal? in other words I'll ask:can every bandpass (or lowpass) filter render a sine-like wave and reject the noise signals with unwanted frequencies ?!
:D v=ir !!! I know that, but I simulated a pattern in Pspice and all current values in the circuit were zero! (Voltages were not zero in some nodes!)
I found a mistake in my design finally. thanks :)
Hi, Can anybody explain the procedure of "Wien bridge circuit" in brief please? Does it have any input signal? I think it is not anything more than a bandpass filter that is combined from a lowpass and a highpass in series, how does it produce Sine wave?
Hi everybody
Im going too place a voltage divider between Ground and a point of 15V (dc) with 2 resisrors. The current in the resistors is exactly 0. Does anybody know that it would work in practice or not?! thanks
to have a high frequency limiter,just replace two Zeners with one cap and use a lower resistance . but it wont feedback the current as good as your previous circuit! in this case, the feedback factor will vary with frequency, and you know that it is a filter! so, some parts of input signal wont...
I think u should collect some info about details of lessons of each program and choose just based on your interest. any field of EE is alive and progressive :-) good luck
look,every where that u want to find common mode input impedance,u should apply two equal dc voltages to the both v1 & v2 and analyze the circuit.(in image1 Zd will have no voltage so it is open. and C.M. impedance is 2Zcm || 2Zcm. in image2:voltage of Zd1 & Zd2 & R0 will be zero and c.m...
