| Functions | Arduino Reference | Maxim's API | Details |
|---|---|---|---|
attachInterrupt()detachInterrupt()
|
digitalPinToInterrupt(pin) required as 1st argument on some boards |
digitalPinToInterrupt(pin) should not be used |
|
analogReference() |
type of reference can be one of: DEFAULT, INTERNAL, INTERNAL1V1, INTERNAL2V56, or EXTERNAL |
type of reference can be either DEFAULT or EXTERNAL | |
analogRead() |
number of pins varies by board | A0 to A5 available with restriction. A0 and A4 are connected to same pin, similarly A1 and A5. A0 to A3 range 0-1.2v A4 to A5 range 0-6v. On reset A4, A5, A2, A3 are active. |
Use functions:changeA0_A4()changeA4_A0()changeA1_A5()changeA5_A1()to switch between channels. |
analogWrite() |
Few pins can be used for PWM output | Any GPIO pin can be used to output PWM | Uses PWM to output signals. |
analogReadResolution()analogWriteResolution()
|
Selected board families have the capability of changing the resolution | All boards are capable of setting analog resolution. | Default resolution: Read - 10 bits Write - 8 bits Maximum is 16 bits resolution. |
useVDDIOH()useVDDIO()
|
Not available |
useVDDIO(pin) sets pin to 1.8vuseVDDIOH(pin) sets pin to 3.3vFuntion returns 0 if success, -1 if error. |
Default I/O voltage on most pins is 3.3v |
