Description

Hi,

There is 2 function i tried to use :
digitalWrite8 and wiringPiSPIxSetup which can be found in wiringPi.h & wiringPiSPI.h but for wiringPiSPIxSetup, it is not defined anywhere and digitalWrite8 is commented inside wiringPi.c
Resulting of :
RPI_SPI.cpp:(.text+0xbd): undefined reference to wiringPiSPIxSetup' RPI_SPI.cpp:(.text+0x3c7): undefined reference to digitalWrite8'

I don't know if there is an hidden reason for that or if i miss something.

Thanks in advance,

Research direction

Compare the declarations in wiringPi.h and wiringPiSPI.h with the implementation in wiringPi.c, noting that digitalWrite8 is commented out and wiringPiSPIxSetup has no definition. Start from the reported linker errors and determine whether these APIs are intentionally unavailable or missing; done means the intended functions are consistently declared and linkable, with the reason documented if they should remain unavailable.
