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

i am doing a countdown timer with 8051 for my project, unfortunately our professor had to take a leave of absence before he could teach us most of it.. can someone explain the .asm code of it for me?

hello! newbie here. i am kind of a guy who hates using ready - made existing libraries, so this helped a lot as i was trying to control and write to a character lcd display. however, i can't figure out how to set the cursor position. for example, i want to set it to the 5th column in the first row, so position 5. so according to the table, i am sending 10000101 on the 8 data lines of the lcd (register select pulled low). the cursor does not move there however. and i cant move the cursor left or right too. is it something wrong that i am doing? thank you.
