Isoveli sanguino

Tekijä OH6HGN on Joulu 22, 2009

Pojat ovat tehneet arduinosta isomman. Siinä on käytössä ATMEGA664 prosessori jossa on 32 IO linjaa. Tokihan löytyy ATMEGA128 myöskin jossa onkin sitten hieman enemmän pinnejä.
Tässä pieni lainaus sanguinon sivuilta

The digital pin functions are identical to the Arduino, with one difference: there are more of them!

The Sanguino has 24 normal digital pins, numbered 0-23. As with the Arduino, you can also use Analog pins as Digital pins. Digital pins 24-31 correspond to Analog pins 7-0. Its sort of backwards, but that means Analog 0 is Digital 31, and Analog 7 is Digital 24.

Some of the digital pins have extra features you may want to keep in mind when choosing pins:

* Digital 2 – Interrupt 2
* Digital 3 – PWM
* Digital 4 – PWM
* Digital 5 – MOSI (used for SPI)
* Digital 6 – MISO (used for SPI)
* DIgital 7 – SCK (used for SPI)
* Digital 8 – Rx0 (this is used by the USB<->Serial port)
* Digital 9 – Tx0 (this is used by the USB<->Serial port)
* Digital 10 – Rx1 (this shared with the extra serial connection) / Interrupt 0
* Digital 11 – Tx1 (this shared with the extra serial connection) / Interrupt 1
* Digital 12 – PWM
* Digital 13 – PWM
* Digital 14 – PWM
* Digital 15 – PWM
* Digital 16 – SCL (used for I2C)
* Digital 17 – SDA (used for I2C)

These extra features are optional, and the pins function as digital I/O pins by default.
