If your program will perform SPI transactions within an interrupt, call this function to register the interrupt number or name with the SPI library. This allowsSPI.beginTransaction()to prevent usage conflicts. Note that the interrupt specified in the call tousingInterrupt()will be disabled on a ...

The function text is measured more accurately in RC2.Users are encouraged to upgrade to fix this bug.Existing functions may need to be fixed, as well. Make sure the {} balance.Defining a function within a function fails. That's ok, for now....

You use theEEPROM.update()function as follows: EEPROM.update(address,value); At the moment, we have 9 stored in the address 0. So, if we call: EEPROM.update(0,9); It won’t write on the EEPROM again, as the value currently saved is the same we want to write. ...
This can be useful if you need to keep track of time, which you can do by storing the result of the millis call and then comparing with another millis call at some later point, as shown here: long timer = 0; void setup() { timer = millis();// get the timer the first time } ...
