Analog Digital Conversion ??

Hi,

Welcome to the forum. The operators "*/" and "//" can be found in the 'Math Operators' section of the PBP manual.

Now, about your other questions, many of us don't have the good habit of writing a good comment after every line of code. So, I am not sure what the programmer wanted to do there. Maybe somebody else here has a better answer.

If we knew what this code was written for we might be able to answer your other questions, but random code ...

1 is clearly an offset. The reason for using it is unknown, it could depend on the necessity to alline the reading with other device

1250 is a coefficient for converting the ADC reading into volts. The actual coefficient should be 12.5 but due to the integer math limitation the author did multiply it by 100 to obtain 1250 and then he devide the product by 100.

All these numbers are related to a specific application, so you should ignore them, since very likely, your application will require different numbers as coefficient and eventually an offset.

Cheers
