    Timer Calculator for any MCU

    Tired of boring calcs? Let me simplify your Timer based projects.

    A simple program that calculates up to 6 parameters to help you using Timers. It is done to be used with ever single MCU (PIC, ATMEL, Freescale, etc) and plataform (Arduino, Raspberry, Edison, etc). Just enter yours parameters and let the program calculate all the needed values to help you. It also saves a .txt file with results, if you need to see it again later and save your inserted values (no one likes to retipe values everytime, right?) Isn't program translated to your language? Use the e-mail in the program to know how to translate the program to your language. Missing feature? Contact via email too. Want to help me to develop for Mac or Linux? You know the way (:
