 # Porting to non-Arduino Platforms
 
-There are several things that have to be done to port RadioLib to a non-Arduino platform. First, since RadioLib is written in C++, you have to make sure your build system can compile C++ files. Next, you have to make sure your build system DOES NOT define the macro `ARDUINO`. If this macro is defined, RadioLib will attempt to automatically detect which Arduino is being used. If the macro is not defined, RadioLib will attempt to include the file `noarduino.h`, which has to be provided by your build system (e.g. by using GCC's `-I` flag).
-
-The `noarduino.h` file has to define all the platform macros shown in [Custom Build Configuration](https://github.com/jgromes/RadioLib/wiki/Custom-Build-Configuration) - this includes callbacks to Arduino functions, like `digitalRead()`, or `tone()`. Therefore, your platform has to define an equivalent of these functions. For example, in STM32 HAL, there's a function `HAL_GPIO_WritePin()`, which behaves similarly as Arduino `digitalWrite()`, but has an extra argument - the GPIO port. Therefore, an appropriate wrapper should look something like this:
-
-```c++
-// noarduino.h
-// forward declaration
-void wrap_HAL_GPIO_WritePin(uint8_t pin, uint8_t value);
-
-// callback argument macro
-// the first argument is the return type of the wrapper function
-// the second argument is the name of the corresponding Arduino function
-// all other arguments are the arguments of the wrapper function
-#define RADIOLIB_CB_ARGS_DIGITAL_WRITE              (void, digitalWrite, uint32_t pin, GPIO_PinState value)
-
-// noarduino.c/cpp
-// now the implementation - pin number also includes the GPIOx port
-void wrap_HAL_GPIO_WritePin(uint32_t pin, GPIO_PinState value) {
-  if(pin > 16) {
-    HAL_GPIO_WritePin(GPIOB, uint16_t pin, GPIO_PinState value);
-  } else {
-    HAL_GPIO_WritePin(GPIOA, uint16_t pin, GPIO_PinState value);
-  }
-}
-```
-
-This has to be done for all Arduino functions listed on the page [Custom Build Configuration](https://github.com/jgromes/RadioLib/wiki/Custom-Build-Configuration).
-
-Once done, the last thing left to do is to initialize all callbacks defined in the `noarduino.h` file. The callbacks themselves are generated by RadioLib - the user only has to call the initalizing functions:
-
-```c++
-// some random NSS/IRQ/RST/GPIO pins
-Module mod(1, 2, 3, 4);
-SX1278 radio(&mod);
-
-(...)
-mod.setCb_digitalRead(::wrap_HAL_GPIO_ReadPin);
-mod.setCb_digitalWrite(::wrap_HAL_GPIO_WritePin);
-// etc. for all the callbacks
-(...)
-
-// we can go now!
-radio.begin();
-```
