Line 21 and 22
@Fat-Fly That's standard practice in C programming. It avoids problems when the file is included more than one time. It is not an error.
Why are you asking?
I copy mysensors library to comp and trying set nrf_gw power to max and these errors. Then verify sketch and arduino ide says this error in myconfig.h line 21 and 22
Then this error is okay but arduino ide not find DigitalIO.h.
/home/insippo/sketchbook/libraries/MySensors/utility/RF24.h:20:23: fatal error: DigitalIO.h: No such file or directory
I do not understand why arduino ide not find this.
Isn't that DigitalIO -thing what happens when you forget to disable 'soft SPI' back again after compiling e.g. EthernetGW ?
I so not disable soft spi if i install gw. After i try.
