[AVR club] External ADC - magsina - Oct 4 15:03:32 2008
Hello friends
I'm making a line follower robot. i decide to use external ADC(my
micro controller is MEGA16). but I don't know
what the name of the chip is(8 bits external ADC)!!!
also i don't know anything about writing the program for external ADC
(i use codevision )and i don't know how it send the digital output to
micro controller. because the input of micro should be analog or
digital 0,1. for example you cant send 234 to micro controller!(am I
right?)
by the way i don't like to use op-amp or internal ADC.
Would you please help me?

First off, you aren't going to be able to do anything wothout a data sheet
for the external ADC you're using. DO you know the part number and do you
have the data sheet?
If not, you might as well give up on that setup.
If you do, the data sheet should give you the info on how to set up and
use the chip.

Use the ADC on the atmega16, it is pretty easy, way easier than using a external ADC. Although it uses GCC (WinAVR), I would suggest looking at the SRS workshop robot for an atmega16 ADC example.

I wanted to know the name of that chip(8 bits external ADC)
also i told that i don't want to use the ADC of mega16. because you
can't use PWM and ADC simultaneously(mega16 may hang!!!)
so would you help me find a good external ADC and tell me how it works?

There are dozens of 8 bits external ADC chips.
The ATmega16 can do ADC, PWM and serial I/O without breaking a sweat.
Again, look at the Example SRS Workshop Robot code it's a good example.
Or take a look at Pascal Stang's AVRLib examples not to be confused with
AVRLibc

[AVR club] Re: External ADC - vid_tech - Oct 6 2:00:25 2008
Hi,
ADC0801 to 0809 are 8 bit parallel interface type ADC from national semi.
PCF8591 from philips (NXP) is 8bit ADC with I2C interface.
But why don't you use internal 10 bit ADC of mega16 ?

I have never had any trouble with using the ADC and PWM on any AVR chip at
the same time. In fact, it's a great way to do simple DSP of audio
signals (FIR filters, etc).
Whoever said they had problems probably didn't initialize the functions
properly.
The data sheets should show you how to initialize the correct registers.

Hi friends,
Well, I never find anything wrong also when using internal ADC of AVR uC (Mega8, Tiny2313, Mega8535, and the latest, Mega128). It worked fine in control system using ADC to digitized sensor data and PWM to drive DC motor at the same time. Maybe you should check the configuration code or change your uC :)
But if you insist on using external ADC, I have ever used one, but serial 12-bit, TLV2543. Great one, but a little bit complex in the code, it is up to you.

Adam
