Can't tell you what typical loading would be in a hotel but we supply energy saver units for use in hotel bedrooms. These are switches operated by the guest's keycard so that when they leave the room (taking their keycard with them) the power in the room is shutdown hence reducing the amount of...
Has anyone tried or does anyone have any experience of transmitting audio using PWM over low cost digital RF transmitter/receiver modules?
I'm looking at some of these license exempt modules and wondering if I can manage to pursuade them to send and receive low bandwidth audio using PWM.
Any...
I'm pretty sure you can do this in all the most recent versions of protel. You import the shape as a .dxf / .dwg.
Prety standard functionality on pcb packages these days.
Are you really looking for specifically GCC or are you really just looking for something free, open source or running on *NIX?
The 51 family, as you refer to it, has an awful lot of branches to it now. There are a lot of manufacturers making 8051 variants all of which are different and may need...
Are you sure you've got the data direction register set correctly?
Are you also sure that you haven't got the output programmed to require a pull up resistor (sorry not familar with that micro, but you can generally programme outputs with or without pull-ups).
With the right kind of FET you...
Hi Guys, wonder if anyone can help.
I'm looking at a project for filling station forecourts involving the monitoring of transactions (from dispenor nozzle lift through to customer paying) and was wondering if anyone had any good pointers to sources of information on standards for communications...
Hmmm...some interesting points.
We get some returns, but almost invariably when they're tested we find they work just fine and the problem is with the way they were installed or used. In this case, once the product has gone back through the test and inspection process (replacing any damaged...
I use both PIC and Zilog products (actually using the eZ80 in a couple of things, haven't used the Z8 itself in years) and I'd have to say I much prefer the Zilog.
There's nothing really all that "wrong" with the PICs in my opinion, I just don't actually "like" them very...
