- Divider.Prg
- A program to calculate potential dividers.
-
- Intro.
- ¯¯¯¯¯¯
- If you've ever tried to work out all but the most simple potential dividers,
- you'll know what a pain it is. And anyway, when you end up with some values
- off resistor, you've never got them in stock.
-
- So, hence this program!
-
- It will calculate the most accurate potential divider possible, either from the
- standard E12 and E24 ranges of resistors or from a set of resistor values you
- have specified. It also shows the actual output voltage obtained using those
- values, and thus the percentage inaccuracy.
-
- How to use...
- ¯¯¯¯¯¯¯¯¯¯¯¯¯
- Run the program. You are presented with a menu bar at the top of the screen.
- To calculate a potential divider, go into the Options menu, and click on
- 'Calculate...'. A window will open and you are prompted to enter the input and
- desired output voltages. Then the program will chug away and calculate the
- best way of doing that.
-
- To set up your own custom values, click on 'Set stocks' in the Options menu.
- A window will open and you are prompted to enter up to 100 values of resistor
- to use. Actually, the program could use many more than 100 values, but after
- about this many, the increase in time taken becomes disproportionately large
- compared to the further increase in accuracy. You may now use this set of
- custom values for calculations by selecting 'Use custom only' in the Options
- menu.
-
- The options in the Stock menu are pretty self-explanatory; 'Clear stocks' wipes
- any custom resistor values, 'Load stocks' and 'Save stocks' load or save a file
- containing all the custom resistor values, to save you typing them in all the
- time, and 'Show stocks' shows all the current custom resistor values.
-
- That's about all it does, but I find it very handy, and certainly faster than
- the old pocket calculator!
-
- Possible enhancements for version 2.
- ¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
- - Able to make up serial/parallel resistor networks for greater
- accuracy.
-
- - Faster calculations.
-
- - Able to compensate for loading effects.

-
- This program is SHAREWARE.
- If you use it a lot, then please register it with me, at only £5.00. Yes,
- that's right, just one crinkly fiver. For this lordly sum of money you get
- the next update of the program, the source code ( in Gfa basic and 68k
- assembly ) and the satisfaction of knowing that you are helping a good cause
- and supporting the Shareware concept. Look at it this way - if shareware
- authors get rewarded for their time and effort, the big software companies will
- not be able to demand such high prices, because the shareware software gets
- better and better, so we all gain.
