Hi

How to solve the given equation

P=10^1.667(ADC output value)-11.33

Aim using Keil51 evolution version and 89c51 controller.

Regards

Your equation isn't very clear.

Do you mean?

$P=10^{1.667}(ADCOutputValue)-11.33$
$P=10^{1.667(ADCOutputValue)-11.33}$
$P=10^{1.667(ADCOutputValue)}-11.33$

As with anything like this, you need to simplify and break it into stages. It might also be possible to simplify it a great deal.

You really need to explain what you're trying to do!.

Hi

Thanks for reply

Aim using same equation what you are mentioned in the reply.

Aim using Keil51 evolution version software and 89c51 controller.

Keil51 is restricted to 2K memory only.

Please proved tips for solving and programming the equation in keil51.

You should you SDCC [http://sdcc.sourceforge.net/] which is a free and opensource with no limitation of size of your code.

I use it with MIDE-51 and Eclipse as IDE, it is also not bad for a free tools:

To install, see

Which one? I mentioned three, is it a, b or c?

iam using b.equation

I think, if you work with log, it will be easier

log(P+11.33) = 1.667*ADCOutputValue

which is a linear equation

y = m*x

I think, it is depend on your application.
