Hello,

Operation: Converting an RS 232 signal to TTL signal

Description: I know this can be done using the IC MAX232

Problem: I’m searching for a simple device that gives RS 232 signals as output. Please note that the device’s pins should be such that it can be connected to the IC on a breadboard. It is better if the device is a commonly used one.

Hi all,

I need a matlab code about QRD-M algorithm. This algorithms is an Tree search algorithm.

Thanks a lot

Hi everyone.

I have tsmc18rf record with all required files. we attempted to supplement that new library so we can make simulations and layouts in this technology.
I go File-New-Library. Appears new window where we give a name to my technology, ande where we should select Technology File. we check “Compile an ASCII record file” afterwards go Ok. Now we need to bucket record file. One singular file! we don’t know where it is placed, what prolongation does it have….? we found some techfile (without extension!) though it creates usually steel layers in Cellview, there is no any mos, diode, or somehin else. I’m regulating Virtuoso 6.1, and have never before use Cadence (nor Linux :S ). we have to finish few projects for graduation with this so greatfully assistance me.

Can anyone assistance me?

I wish to have a voltage supply to my condensor microphone 48v from 2 AA Batteries.

Thank you.

But with it, a PIC house can't get on , only comes a energy LED and goes off and afterwards one off …….

I consider a bucket of a PIC house is not adequate for a charger,
can we make it work with a small alteration ?

Each DS18S20 has it’s own address programmed into it during manufacture. At the moment you are probably using a “skip ROM” command (0xCC) so no address is needed. Instead you should use command “Match ROM” (0×55) and the address of the specific DS18S20 you want to read. If you do this you can simply wire as many sensors in parallel as your cabling will allow.

If you do not know the internal address of each sensor, I suggest you connect them one at a time and use the “Read ROM” command (0×33). Make a note of the address it returns and code it into your program. There is an algorithm on MAXIMs web site for searching for addresses while several are connected in parallel but it is quite complicated, it’s much easier to read them one at a time.

Hi
I am training to use Cadence by conceptualizing an appetite liberation inverter circuit.
I’m a bit stranded bargain what these blunder messages meant in a DRC checker.
if there is a couple where we can find an reason greatfully let me know, differently I’d unequivocally conclude some assistance bargain a following:

1. Welnotr_StampErrorFloat
(NWEL is highlighted)

2. 4:16n Maximum N+ Diffusion to nearest P+ pick-up spacing (inside P-Well or T-Well) is 20um
all nmos freeing highlighted

concerning beliefs of counters we don’t have most information, so greatfully advise me some books and any books for digital IC pattern is OK

thanks for your help

I am Sending Data Through GPRS using SIM300DZ
I am making connection by Following commands..
Through these commands i connect to server successfully. I send any thing to uart its receive on server. But i want to send data through at+cipsend.

How to solve this problem???

hi guys .. i am a newbie here. i am designing a band stop filter fr my academic project.i will have to build a hardware prototype on ATMEGA 32 micrcontroller. i am going to design it using MATLAB fdatool and FIR least square to find coefficients. after that i will use filter coefficients to write a C code to be burned in microcntroller. i am also using proteus 7.7 for simulation of hardware.

so.. i want this stop band filter to filter out 50Hz mains humm noise from an audio signal.
s here are a few questions i would like to ask..

first of all will this ATMEGA32 microcontroller be able to provide enough computation resources to support this kind of audio application at all.. i mean the will inbuilt ADC be fast enough to do this..

how do i decide order of the filter, sampling frequency, F pass 1,Fstop1,Fstop 2,Fpass2 (well i guess Fstop1 and Fstop should be 49 and 51 for 50 Hz stop band if i am not wrong) in fdatool.

thanx for the help guys..
