Hola a to2... les quiero hacer una consulta ... quisiera saber si se puede usar un programa para un MSP430 en un pic 16F627/8..., obiamente hay que modificarlo pero no se por donde empezar
habra algun programa que lo haga????
muchisimas gracias!!!
// MSP430 based Tea Timer
// Sets off a buzzer to let you know when your tea is done steeping
// Supports several types of tea
// suspended-chord (http://blog.suspended-chord.info)
/* Tea steeping chart
Tea type Time DIP Code
------------------------------------------
White 2 minutes 000
Green 3 minutes 001
Black/Oolong 4 minutes 010
Herbal 5 minutes 011
Chai 8 minutes 100
Rooibos 6 minutes 101
Other 1 minute 110
Other 2 30 seconds 111
