how to name gpio-pins

[bmw-freak]

Code: [Select all] [Expand/Collapse]

1. Hello
2. as a beginner I am not shure how the pins in a program shuld be named.
3. Example code:
4. // Use software SPI: CS, DI, DO, CLK
5. Adafruit_MAX31865 max = Adafruit_MAX31865(10, 11, 12, 13);
6.  
7. What should I write:
8. Adafruit_MAX31865 max = Adafruit_MAX31865(P10, P11, P12, P13); (par example)
9. or only
10. Adafruit_MAX31865 max = Adafruit_MAX31865(10, 11, 12, 13); ?
11.  
12. Is there a hardware spi (at which pins)? In addition to I2C, which I also need.
13.  
14. Thank in advance
