Hello Everybody,
I am going to design a PCB which holds an FPGA, and I wanna use an external RAM on it too. Can you tell me please the frequency limitation of PCB, commercial or even high tech. PCB.
Thanks in advance,
Hani
You can choose any resistance for your pullup depends on the suitable current for your application, and the max. current that micrcontroller can bear, I think for PIC it can sink up to 25mA, read the datasheet.

DC- MOtor control using PIC, you need and need to know:
,
1- If you want to control just on/off and directions it is easy to do, and what you need is power bridge to decide the direction, and you can buy this bridge as an IC but it is expensive somehow, so you can build it by yourself using 4...
Hmmmm, you are mashkaljy/mashkaljyah.... Asking the same question many times!!! From which university you are? I am sure you are from Jordan, isn't it :D.
I would like to help you, but I am (hen mang) very busy these days. If you remind me this satureday. I will help you from A to Z.
Good luck
Hmmmm, you are rounding on the same point. The most important thing here is using external interrupt pin for this purpose, either postive edge or negative edge.
When the square pulses pulsed on that pin, it makes interrupt then you can count each interrupt action which is equal to one pulse.

It is easy man, think about this... each leg of microcontroller has two protection diodes (zener), if the applied volatge is over 5 volt, let us say 220 Vrms, then the zener will cut it to 5 volt, and if it is -220Vrms, then the another zener will work in forward and make the volatge almost...

It is quite easy doing so. pic16f872 has built in 10-bit A/D, so what you need is to follow up the steps:
1-Prepare for this chip and the programmer and Kit to program and test your code.
2-I suggest you use C lang, CCS from (www.ccsinfo.com) is very good one...
No body could help me :cry:, I need just like a reference book or site to do simulation for a communication channel in general but using Matlab please.
Thanks in advanced
Hi Engineers,
Hello, I would like to do a simulation for this communication cahennl as shown in the figure below. Please if you could guide me to do so using Matlab. Thanx.
