PWM using PCA in AT89C51CC01

you first have to know how ADC works..

you can get some basic information about ADC here:
http://www.8051projects.net/adc-interfacing/introduction.php

Now ADC converts analog to an equivalent digital value. This digital value is measure of steps taken by ADC to reach that analog level. each step of adc provides the resolution of that ADC. if ADC is an 8-bit resolution so it has 255 steps, 10bit ADC h... Read Compelte post

How to measure current? (ADC08034 interface to the AT89C52)

emm...I'm not sure, the Table-4 MUX Addressing:ADC08034 no show the "-" in table. It just have "+".

Ya, I would like to share with you that I found a great ADC which we can scale up to 100A, we can use very least pin interface with uC and EASILY to control. Try to search LT1787HV and LTC1286 chip.

Please give some comment...

Thank You.

questn is abt the resolution concept of ADC..

If you have an A/D converter reading an analog voltage, with a reference voltage of 5 volts, your reading will be "referenced" to this 5 volt value.

For instance, if you input voltage is 4 volts, then you are reading 80% of your reference voltage, right? (4/5 is 80%)

The resolution, or "how well you can resolve" this reading, is described in bits. An 8-bit A/D divides up the reference voltage into... Read Compelte post

How to measure current? (ADC08034 interface to the AT89C52)

Hi,

Anyone use ADC08034 before?

How can i measure current? I found one application from ADC08034 datasheet which i think can measure the current? But then I'm confusing the Digitizing a Current Flow Application show in datasheet page-17. ADC08034 don't had Vin(-) and Vout(+) pin. I wondered why this application using 08034. If we try to use ADC08031 for this application but this IC miss one pin fu... Read Compelte post

Hello everyone, using software uart is a very good idea for a second serial port. Thank you so much. I would kindly like to know how to connect this port to the PC?
