Timer-Prescaler tool for PIC16/18, PIC24, dsPIC33 and PIC32.

This Excel sheet provides some tools to choose the prescaler value of a timer.

It provides the following tables/functionalities:

1. A "Calculator": calculates the prescaler and the needed # of timer steps, given the MCU frequency, the time wanted in how many steps. Also manual entry for the prescaler is possible.

2. The calculation of the input frequency of a timer (both in MegaHertz and KiloHertz), given the MCU clock in Mhz and the value of the Prescaler.

3. The calculation of the step time of a timer (both in microSeconds and milliseconds), given the MCU clock in Mhz and the value of the Prescaler.

4. The "Range" of the 8 bits timers (both in microSeconds and milliseconds), given the MCU clock in Mhz and the value of the Prescaler.

5. The "Range" of the 16 bits timers (both in microSeconds and milliseconds), given the MCU clock in Mhz and the value of the Prescaler.

6. The "Time" a timer needs to make "x" steps. For 8 bit timers "x" is 0..255, for 16 bit timers "x" is 0..65535.

Have fun!

2013-09-17: Added a "Calculator" sheet: calculates the prescaler and the needed # of timer steps, given the MCU frequency, the time wanted in how many steps.

---------------------------------------------------------------------------------------------------------------------------------------

Version 3.0, 2013-09-18: Added timers with other prescaler values to the "calculator".

--------------------------------------------------------------------------------------------------------------------------------------

2013-09-18: added a manual prescaler selection to the "calculator".

--------------------------------------------------------------------------------------------------------------------------------------

2013-09-19: corrected a small error in the "% error" in the "Calculator" sheet.

---------------------------------------------------------------------------------------------------------------------------------------

Version 4.0, 2013-09-20: added the calculations for PIC24m dsPIC33 and PIC32.

---------------------------------------------------------------------------------------------------------------------------------------

2013-09-21: Made clearer how to use the calculator output with timers generating an interrupt on overflow.

--------------------------------------------------------------------------------------------------------------------------------------

Version 5.0 (2013-09-26): added the postscaler value to the Calculator sheet.

-------------------------------------------------------------------------------------------------------------------------------------- 2013-12-23: Corrected an error in the "Calculator" sheet (gave an excel error).

WattMeter (Power meter)

5

This project is a power meter (Wattmeter). It is made for 230V~ (nominal, rms), 2.5A~ (max, rms) and 50Hz, but is rather easily adaptable to other voltages, currents and frequencies. It can handle both sinusoidal and non sinusoidal voltages and currents, both with and without DC component.
