Hi,
I have 2 modules ( 1 UART and another module used to test external SRAMs ).
Every single module is working prefectly when alone on the Spartan 3 borad.
when i put them together, the UART doesn't work anymore. i have the clock excessive skew problem, and i'm pretty sure it comes from...
When dealing with 220 AC voltage, we usually need to filter the 50 and 60 hz frequencies.
My question is : do i need to place a low pass filter before inputting an analog signal to an ADC .
the circuit i'm dealing with uses a Psoc connected to many pressure sensors, the circuit will later be...
eeprom addressing
Hi fatehi,
The AT24C256 is a 256 KBits memory and not 256 Kbytes.
So 256 Kbits = 32 Kbytes = 512(pages)*64(bytes).
I can't answer your first question (i'm not familiar with BASCOM-AVR), but there is basically 2 difrent ways to adress such an EEPROM through a compiler...
Re: pcb in protel
Hi ebi82,
Once you're finished with creating the schematics, you have to :
1- Annotate your components {Tools → Annotate} , u click Update changes, then Accept changes. (figure-1).
2- A new window shows up, u click Execute changes, then close. and after that save your...
Hi ibrahim,
As IanP described, u can use a simple voltage divider.
Besides that, there is come voltage divider ICs , use them especially if u want to hit a high precision. U have also the current question to carry about .
Here is some Voltage divider ICs u can use :
**broken link removed**...
how to increase volt
Hi binary2007,
i'm sorry for the delay, i included here a part of a circuit i used lately.
i'm assuming here that u already got your 0 -- 5 volts pwm working and you already filtered it.
You will use the filtered PWM signal and amplify it with this AMP op based...
Hi eng_mahmoud87,
This is very simple, u can use a simple resistors divider to measure the voltage .
Concerning the current, u will have to measure it by measuring the voltage across a resistor and manage to do the math with your soft.
Hope this helps,
regards,
Hassen.
increase voltage
Hi binary2007,
Well, if you want to get up to 45 V from your 5 volts PWM source, you can always use an OP AMP and fix its gain to 9, ( u can manage to put a little pot in the feedback loop of the AMP for fine adjesting later on ). concerning the current a simple transistor...
Re: RFID BOOKS
You can search the "EDA E-books Upload/Download" section, you'll find some books there.
here is 2 examples :
1)
2)
If you can't find the book you are looking for, just ask in the "EDA E-Book, Articles & Specification Requests".
Hope this helps.
Regards,
Hassen.
Thanks for your reply blueroomelectronics, i'm sure i've already seen a little test circuit for PICs but can't find it anymore.
It was a few resistors circuit that connects some of PIC pins and by measuring the voltage across 2 pins of the PIC you can tell if it's still responding or not. . .
