It is possible to do it with your board but you will have to write
some code before it will work the way you want it to.&lt;/p&gt;

Your second attempt at specifications:&lt;br /&gt;
&amp;quot;OK&lt;br /&gt;
I write here all I have and what I want&lt;/p&gt;

&lt;p&gt;
I use mc Infineon SAB 80C535&lt;br /&gt;
eprom is 27SF512&lt;br /&gt;
ic2bus is PCF8574&lt;br /&gt;
ADC max1168&lt;/p&gt;

&lt;p&gt;
and i must record on 2 inputs teh signal from 2 hall sensor (0
volt 12 V) and the motor are 6000 rotation/minute...&amp;quot;&lt;/p&gt;

&lt;p&gt;
I can&amp;#39;t see anything that claims that you need to &amp;quot;record(to see
if is low and high) the signal at the maximum speed(6000/min) of
motor at both sensor chanel and to see time diferents&amp;quot;.&lt;/p&gt;

&lt;p&gt;
Why are you constantly posting subsets of the specification that
does not cover the parts that you request help with?&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: signal record on the analog inputs</title><link>https://community.arm.com/thread/148031?ContentTypeID=1</link><pubDate>Thu, 08 May 2008 06:03:48 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:9365db64-ba23-4fd6-973f-195379481a45</guid><dc:creator>rotar tutzu</dc:creator><description>&lt;p&gt;&lt;p&gt;

If you need to talk with someone, I think your teacher would be a
good idea. He gets feedback from the other students too.&lt;/p&gt;

&lt;p&gt;
Record a number of samples and print to the serial port. With
enough baudrate, you might be able to print in rea-time. An
alternative is to see if you can store a number of samples in a RAM
array and print. You don&amp;#39;t need to seem many samples to verify that
your ADC picks up valid samples.&lt;/p&gt;

&lt;p&gt;
You can also collect min/max/average/standard deviation and print
- that gives you information about what the ADC picks up.&lt;/p&gt;

&lt;p&gt;
The number of poles should not represent a problem - it just
affects the required sampling speed. But you still don&amp;#39;t need to save
anything in EEPROM. Your fight with the EEPROM may take more time
than to actually do what the required work. Doing extra is a good way
to learn - but that obviously requires that it is YOU who do that
extra work. Asking for other people to chip in to solve problems you
do not need to be solved is quite counterproductive, don&amp;#39;t you
say?&lt;/p&gt;

is not necesary to record in eeprom , I want to record because I

Normally, you must write floating point numbers? Why? The ADC will
not produce any floating point samples - why would you want to
convert your data to floating point? Your specification doesn&amp;#39;t say
anything about converting raw measurements into calibrated physical
entities according to the SI system. If you don&amp;#39;t have any need for
volt, henry, tessla, ... what would your floating point conversions
then do? And if you really do have to play with decimals (such as
decimal RPM) - why not use fixed point arithmetic? Too simple with
integers? Too small code? Too fast?&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: signal record on the analog inputs</title><link>https://community.arm.com/thread/135360?ContentTypeID=1</link><pubDate>Thu, 08 May 2008 05:10:50 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:227dc4e5-1418-4b05-9165-0428f5c70cd9</guid><dc:creator>ImPer Westermark</dc:creator><description>&lt;p&gt;&lt;p&gt;
6000rpm is 100 revolutions/second. But where do you have any
specification that you must record 100 samples/s and store in the
EEPROM?&lt;/p&gt;

&lt;p&gt;
To know the RPM, you must analyse the data from the hall sensors -
basically counting pulses. But why do you think that you have to
store the raw data? Isn&amp;#39;t it more likely that it is enough if you
emit one RPM value every second? Or do you expect the motor speed to
be very, very, very, very, very quickly modulated? And if so - why do
you believe that? What make you even think that the RPM of a motor
can be quickly modulated?&lt;/p&gt;

&lt;p&gt;
Have you even verified that you need to use the ADC to process the
hall sensor, and that it isn&amp;#39;t enough to convert the data to a
digital signal and then count the digital pulses? Having an external
ADC givs a hint that your teacher may want you to use it - but it
isn&amp;#39;t a proof that it is so. If the board has an external ADC, every
exercise may not require the use of every component on the
development board.&lt;/p&gt;

&lt;p&gt;
i want to record the signal on analog input 1&amp;quot;&lt;/p&gt;

&lt;p&gt;
Nope! Can&amp;#39;t see any requirements about writing 700-1000 meserments
[sic!]/second into EEPROM in your specification!&lt;/p&gt;

&lt;p&gt;
What makes you think that your EEPROM can handle 1000
writes/second? What does the datasheet say? And how large are one
sample? One bit? One byte? Two bytes?&lt;/p&gt;

&lt;p&gt;
And in what way will we be able to help you to get the writing to
take less time?&lt;/p&gt;

13 minutes and you are getting impatient? Are you will ing to pay
for support, or why do you assume that people have even read your
question 13 minutes after you post it?&lt;/p&gt;

&lt;p&gt;
Or do you think this is a payed help-desk? If so - how much do you
pay for accessing this forum?&lt;/p&gt;

&lt;p&gt;
Help with reading data from the ADC? Haven&amp;#39;t you looked at all the
example code available? Or checked the datasheet for your specific
processor? The datasheet contains all information needed to write the
code - without the datasheet, there would be no example code, and
there would be no people who you could ask...&lt;/p&gt;

&lt;p&gt;
Is this a school project? Haven&amp;#39;t you received enough information
about how to do it - or how to find the required information - from
your teacher?&lt;/p&gt;
