Hello all,
I have a need to build a circuit that would send incoming USB data wirelessly to a receiver. Is it possible to accomplish?
If so, would a webcam work with it?
Thanx
Thank you.
But CD4051 and 74HC4051 are 8:1 multiplexers.
Isn't there a IC which has multiple 2:1 multiplexers inside? Much like the MC14551B. But that IC is very rare to find here. almost impossible.
Is there any other equivalents for this? at least a
4x2:1 Multiplexer?
please......
Thank you sir. Im pretty sure this would work. I'll try this as soon and possible and let you know the results.

I'm guessing this too is a multiplexer?
hey..
I have 2 Analog signals (which contains multiple wires) coming from 2 sources and a Device that takes ONE INPUT.
And I want to implement a SWITCH that can select which source to output into the Device.
Any idea how to do that? The signal shouldn't be distorted in any way.
here's a...
hi,
I'm trying to build a device that can switch between two computers into a projector.
The output from one computer will be displayed from the projector. but when I switch, the other computer output should be connected to the projector. Is there any way to achieve this?
(Not talking about...
Hello, Thanx for all the replies. I found the problem and got it fixed. It was a problem in the Serial intterupts.. Disabling and enabling it before the main loop fixed it.
RFID device is working in 5V and the MCU is working in 3.3V .................... So I should pullup to 3.3V ?
wouldn't that give a direct 3.3v input to the device RX line??

Can any1 tell me how to make a 3.3V TTL output become a 5V TTL output???
a circuit diagram would...
ok now whats this with the MAX232...? because it works when I connect it the 1st time AND when I reconnect the cable...
The length of the cable is 4 feet shielded male-female cable...
And if im using pullups, what resistors should i use?
EDIT: I changed the serial cable to less than...
the original code is huge.. its a huge collection of codes..
anyway I tried with a test code, where in the main function, it only has:
while(TRUE)
{
putc(0x04); putc(0x00); putc(0x01);
delay_ms(200);
}
Thats it.. even with that, it doesn't work..
Thanx for the replies.
I tried writing 1 and 0 to TX and RX after reset. it didnt work... :(
And the PIC is working in 3.3V but the RFID reader is 5V. There is a MAX3232 in the serial circuit of the PIC.
If the voltage is the problem, How can it work when the cable is re plugged?
