that i know i cann't get better resolution. Actually as my single varring from 4-20mA is giving me value in 6 digit, if i still use atmega32, can i use that to display this value????
Thanks nandhu for your post. I am already getting same response from some other sources too. but my problem is i am willing to get higher value from atmega32 ADC, value higher than 1023. How i can get that.
if any one having piece of code to do this kindly post.
Hello Friends,
I am working with atmega32 and using its internal 10bit adc for reading 4-20mA signal. But my desired value to be read is of 6 digits so i am not able to read it with 10bit ADC. Kindly suggess any AVR controller with above bit ADC.

Narinder
Thanks for your reply. i am having idea of it.. can you tell me how to calculate pulse value in intruppt?? or i will be very thankful to you if you could send me some lines of code
Hello Friends,
I am doing a small project using AT89c2051. I have done all and project is working fine. Program code is in C. I just want to add a 555 timer ic with it. I googled about its working but unable to get its pulse value. I have used a variable register with 555. I have connected pin...
Hello Friends,
I am having some faulty Laptop Li-Ion batteries. I was willing to do some R&D of these batteries. I opened the batteries and found 6 Samsung cells inside that and a small piece of PCB (I think it is li-ion protection circuit).
I checked the specification of the cells on internet...
Dear, Thanks for your reply but this means that luminous is only criteria???? means higher mcd led are better than lower mcd led???? there must be some more criteria.......i think.......
like if two different type of led gives same light, this doesn't mean both are of same quality......... this...
Hello Friends,
I want to ask you all a very basic but importent question. I survaied the delhi market and came to know that LEDs are aviable in a wide price range starting from 30P to 3-4 Rupees. I am not able to judge what basically the differance is.
When asked people they say, they differ...
I am designing an application which has RS232 interface. I am able to send commands using hyperterminal. I am writing the command and then ctrl+enter. Information goes to the device and works.
I am trying to make it in visual basic but don't know how to add ctrl+enter code after the string...
74hc595 is a shift register having storage for 16 bits. 8 for input buffer and 8 output buffer. You need to connect clock,output enable and data line along with shift register and then on each clock one bit will be inserted in the input data buffer and on active low output enable. this...
Hello Friends,
I am implimenting a very simple project. For that perticular project, i am using a microcontroller circuit having P89V51RD2BN. For the project i don't require much faster microcontroller.
So please advice me which microcontroller i can use in its place which will be totally...
MC P89V51RD2BN Problem
Hello Friends,
In one of my project i was using Phillipse make P89V51RD2BN and it was working fine. Last time i went to market and purchased NXP make P89V51RD2BN IC, considering both the same as phillipse is now NXP.
But while programming these ICs the same program...
