I didn't get it.
Firstly, how can this be solved with just about any PIC? I do agree that assembler provides a better control over instruction cycles and I do program in assembly when the application is relatively simpler to implement. But as far as I know, the problem I mentioned isn't...
Hi everybody.
I've come to EDA Board after quite some time and the reason was I had more pressing needs to satisfy than the craving for embedded electronics. ;-)
I recently started work on a data acquisition system for interfacing a custom made satellite ground station to the PC. The scenario...
Hi there...
I have to use a hardware buffer in an embedded application... The buffer must be FIFO and >64kB...
The data comes on a serial link at TTL level. Obviously, the buffer must store the data byte-by-byte and the on-board data handler then picks it up from the buffer on FIFO basis. It's...
A picture is attached. I found it on web. Looks appealing. Can anyone please identify which software might have been used to design this schematic? Thank you.

I was looking for an AC Power Connector to mount on PCB. I wanted to implement a power supply for my MCU circuit right there on the PCB.
I had to search a lot, but in the end I did come across the right footprint.
As a side note, it is found in default EAGLE libraries by the name of AC...
Yes! There's an idea. Timer interrupts (with high prescalar) can be used... And the controller can do something in the background. :)
But don't you think a key-press could be quicker than 10 times per second? I mean have you seen the younger generation text on their phones? :p
I would like to...
Because otherwise there is not use of using the interrupt method. I am using the interrupt method so that the controller can do something useful when it's not polling. If I don't always power the rows OR columns, there will be no interrupt unless I am running a poll. And in that case, the MCU is...
Hi there.
I always wondered how the keyboards/keypads worked. I found out a while ago that it is nothing but a simple matrix of push switches such that each switch has one end connected to a common column line and the other connected to a common row line... What you can do is, poll either...
I am pretty sure that I did re-run it... Not once, but several times. I read somewhere that sometimes EAGLE gives stupid errors which go away just by quitting and restarting EAGLE. So I saved my schematic ("as is" in the picture attached to thread) and restarted EAGLE control panel. Then I...
I checked and there is not any overlapping of a symbol as well. But I have attached the schematic, nonetheless.
Please guide.
Be sure to comment if you see anywhere else the schematic is lacking.
Thank you all. I appreciate your help. I get it now.
So the ^ shaped pin on the left is not a pin... The pin connected to a filled cylinder is ground and the rest two pins are connected together unless the jack is connected to wall socket. Right?
And I need not worry about the pin in the middle...
So, the screenshot is of a schematic in EAGLE... EAGLE says I have pins overlapping in a certain area... I don't see any overlapping.
Can anyone point out the problem please? Thanks.
Ok. I am not asking for a PCB footprint for a DC Power Jack since I have searched and seen a few members getting scolded over asking a stupid question which could easily be solved by searching. I already have a PCB footprint of a DC Power Jack. I am using EagleCAD and the schematic is confusing...
