RNG Compilation on STM32L073RZ #56

Closed n9wxu closed 4 years ago

n9wxu commented 4 years ago

The STM32L073RZ has a HW RNG with the unfortunate register name of RNG. This collides with the RNGClass RNG; line on RNG.cpp:159

The RNG global needs a new name.

I suffixed RNG with making RNG for a temporary hack. Fortunately I do not need the RNG at this time.

You may also be able to work around the issue by putting "#undef RNG" in various places to remove the definition that comes from the system headers. And then later redefine "RNG_SYSTEM" to the underlying register pointer to use the system random number source as a TRNG.
