Hi radium98,
I agree with karesz regarding the cable impedance.
I suggest you to check if the final output impedance is 50 Ohm as expected measuring the output voltage.
Build a non inductive load usable at the operative frequencies of your circuit.
If possible set the output to a safe level...
Re: SPI and I2S
SPI and I2S are quite different.
But you can assume the following connection:
SPI I2S
MISO nc
MOSI SD
SCK SCK
CS nc
GPIO WS
You can try a SW implementation if:
- your SPI interface has a selectable word length (and...
Hi to all,
I run into a big trouble:
I am very new to linux embedded , and i have to interface an ST M25p16 to a MPC8313E cpu.
I am working on a:
- fresscale demoboard MPC8313E-RDB REVA2
- ltib-mpc8313erdb-20081222 coming from Freescale.
~ # uname -a
Linux mpc8313erdb 2.6.23 #12 Tue Dec...
Try with:
h**p://winavr.sourceforge.net/
It is a GCC target for AVR i am still using that with good results, it works both in Windows and in Linux too.
bye
max 232 function
It is the link of the MAX232 datasheet
I hope that this helps in better understanding of how IC function.

Bye
Sometimes (i know very rare :-( ) is possible to have some more compatibility setting into the BIOS sata parameters PATA mode or similar (standard , IDE etc).
Good Luck (you need it)

Re: What is Cygwin
Take care when you download and install it:
There are 2 types of Cygwin:
- Cygwin , that use normal console style only
- Cygwin/X that allows you to have a quite good emulation of X environment.
Some Another tips:
- when you install it usually , it install a lot of files...
radiocommunication tester cmt 802.2020.52
Hi,
I have A similar model , CMT 802.2020.54 , and now i have the same problem, impossible to find documentation.
Into the meantime have you found something on it?
If i found some document, are you still interested...
I don't have specific experience about quartus linux installation,
but i think that some more specific information is needed. like:
- Output messages,
- when the crash happen?
- Has the remote system the same OS than the host?
- Are the libraries installed the same on both PC (glibc GTK...

Re: noise in microphones
Hi
I need to understand what kind of noise do you hear.
The type give to you informations about the kind of disturb.
"tac tac " sound, can be present if some high Power Transition (EMI emission)
is quite close. (ie. Power Amplifier with big fan cooler speed...
Re: creating voltage supply
The two basic methods are:
-Linear regulator
-Switching regulator
The best way to do this depend deeply from the MAX current
that you need.
If the current is not so high < 1A, and they have all the same GND
the linear method can be the simplest,
and i agree with...
>PLD means Programmable Logic Device.
>ASIC = Application Specific Integrated Circuit.
Yes it is in this way.
>ASICs are built by connecting existing circuit building blocks in new ways. Since >the building blocks already exist in a library,
This often is called Standard Cell device.
>produce...
