Hi Stenzer,
Thanks for your inputs. This is really useful.
I'm using the attached commands. Interface is USB. Internally the commands pass through UART. Defined COM Port & Baud Rate 9600.

Hi All,
I'm trying to automate QL355TP Power supply using Python or LabView. If Instrumentation experts out there could you please share your thoughts?
Dear All,
I need Encryption/Authentication Devices for my product.
Specs:
I2C EEPROM
2K Memory
8 bit Address with Family Code '1011'
Is there any product that is available off-the-shelf?
Thanks
Yes. I was wrong. Tiny45's EEPROM is 256 Byte (or 2Kbit). I did choose an 2K EEPROM. However is there a way to define my own Slave address for the EEPROM or is there any EEPROM for which I can set my own Slave Address.
I have to choose between 50 to 5F as Slave address. Any suggestion?
Thanks.
Hi all,
I'm looking for an EEPROM device which is equivalent to ATMEL Tiny45 EEPROM.
I went through the datasheets and shortlisted these parts.
Microchip 24AA256, 24FC256, 24LC256
On Semi CAT25256, CAT24C256
Moreover I need help on finding the equivalent clock frequency as same as Tiny45...
Dear All,
I'm looking for a reliable programmer to program ST M93S46 Chip (Microwire)

I have tried Dediporg. It did not work. If anyone could suggest me some other reliable programmers it's...
Dear All,
I'm trying to capture I2C communication between a Master & Slave using Beagle. Could someone help me to interpret the transactions.
eg.
Write Transaction : 00 00 04 58 1C 10 9D
Read Transaction : 44 20 FA 6C 41 00 01 41 58*
Also I would like to know what the * at the end denotes...
Dear all,
Below is hex data from a hex file. (out 0f 675 files)

Hello,
I need to know how the checksum was calculated for the below hex strings
10 00 00 00 0D 99 03 85 4F AA 5D 33 97 2A 65 CC 2B FF 00 F0 2D
10 00 10 00 00 00 00 00 00 00 00 00 0E 18 93 EB 79 60 1C 17 30
The last 2 digits gives the checksum.
May I know how it was calcualted for the above...
Inverting Op-Amp 1 with Rf=1kOhm, Ri=1kOhm. Gain = 0dB
Inverting Op-Amp 2 with Rf=0.1kOhm, Ri=0.1kOhm. Gain = 0dB
How much is the output impedance of Op-Amp 1 and Op-Amp 2?
Non-inverting Op-Amp 1 with Rf=1kOhm, Ri=1kOhm. Gain = 6dB
Non-inverting Op-Amp 2 with Rf=0.1kOhm, Ri=0.1kOhm. Gain = 6dB...
Hi Everyone,
I'm evaluating an LDO.
Vin=5V
Vout=3.3V
According to my evaluation, Vin discharge timing faster than Vout, will there be any effect due to this?
Please refer to the attached.
Thanks,
Satheesh
Hi everyone,
The Audio signal frequency is limited to 20 to 20kHz.
If we need to convert Analogue Audio signal to Digital, the signal should be sampled at 40kHz. (as per Sampling Theorem)
But why is there 44.1kHz?
I have gone through the below link, which I could not follow.
