A math formula in AD

[sf]

Hi,

Today isn´t a real good day for me, i have been stucked in a math formula, that i can´t realise, well vacations is need........

But if anybody can help me.....thanks in advance.

The formula i need is the next :

Based on an ADC read at 10 bits.
Having the values "MAX" and "MIN".
I need to "translate" the AD read´s to value of "MIN" to "MAX".

For example:
The "MAX" and "MIN" are values that i change any time.
ADC values from 1 to 1024.
Min=50 and Max=300

My result sould be:
for adc=1 -> result=50
for adc=1024 -> result=300

thanks in advance.

Are you sure about your ADC values?.
The normal ADC return for a 10bit ADC, would be 0 to 1023, not 1 to 1024....
Range though is 1023 counts in each case.

Thank you both for this great help.

@Ttelmah
The adc is from 0 to 1023 I´m thinking in another value.
My mistake is when i put 1 to 1024, i´m was thinking to add 1 to the adc reading´s for make easier other values.

It´s another way to see that i need vacations very fast.........


Thank you all.

I believe with the exception of the correction of the min value, we suggested the same idea....(logicwise)

I'll keep that in mind (the min value correction) if I ever need to do something like this.....

nice...

Absolutely.
I started typing my reply before your's was posted, so "wasn't aware of it".
Logic identical.

Best Wishes

yeah it happens...(simultaneous posting)

yours is the " true answer " though... i didnt take in account the min value correction.... because i didnt consider "limit tests" on my inputs for my solution....

cheers
