details
This project shows how to use the Teensy 3.0 and Arduino Ethernet Shield. Teensy 3.0 and Arduino Ethernet Shield are connected to the SPI. Teensy and Arduino have different names of the SPI.
| ARDUINO NAME | TEENSY NAME | TEENSY PIN |
|---|---|---|
| MISO | DIN | 12 |
| MOSI | DOUT | 11 |
| SCLK | LED | 13 |
| SS | CS | 10-9 |
The SPI bus on the Arduino Ethernet shield is broken out on the ICSP header on the backside of the board. The SS lines are on the regular digital pin headers. The Teensy 3.0 uses a different naming scheme for the SPI bus.
