Hi There!

I'm using CY8CKIT-059 I'm codding this on PSOC Creator 4.2 So I need some help

My problem is;

I have 32bit anolog input from potantiometer. IT is around 0-65930 So I want to see this around 0-5,000V  

I made it 0-5000 mV  but I couldn't do 0-5,000V  

So how can I do it?

double Result;

Result = mV / 1000.0;   // Will convert to float

Happy coding

Can you please post your complete project or a shortened version that shows the error so that we all can have a look at all of your settings. To do so, use

Creator->File->Create Workspace Bundle (minimal)

and attach the resulting file.

The 32 bit analog input from your potentiometer can be mapped to the data range 0 - (2³²-1) which is essentially 4 bytes and unsigned int data type can easily accommodate this. However, if you want the data type to store decimal values, you can use the float data type which is also 4 bytes.

uint32 potentiometerInt; // Unsigned int

OR

float potentiometerFloat //float

If you want to convert from one data type to another you can just type cast it.

potentiometerFloat = (float) potentiometerInt

I didn't understand what you meant by 0-5000V, the voltage of the potentiometer can't be of such high value, are you talking about the count? What do you mean by i made it 0 - 5000mV, please clarify.

Thank you so much

0-5000mV means my converted output from potantiometer input when my potantiometer ohm is nearly 0 my output voltage from potantiometer

is 5v so 5000mV 

So i want to  print float number on LCD  i have got input from potantiometer and it is 32bit (int32) so data range

0 to (2^32-1) my problem is I cannot print after point(.) on LCD such as  my converted output is 5,238V but I cannot printing ,238

on LCD my problem is this I can printing 5238mV but cannot that one
