multiple definitions of "microstepcurve"

[W1CMC]

If I try to use both the old and new motor shields in the same sketch, there are multiple definitions of the symbol "microstepcurve" at link time. This is easily fixed since the symbols do not need external linkage (arguably, they are externals only by accident): change

Code: Select all

#if (MICROSTEPS == 8)
uint8_t microstepcurve[] = {0, 50, 98, 142, 180, 212, 236, 250, 255};
#elif (MICROSTEPS == 16)
uint8_t microstepcurve[] = {0, 25, 50, 74, 98, 120, 141, 162, 180, 197, 212, 225, 236, 244, 250, 253, 255};
#endif

to

Code: Select all

#if (MICROSTEPS == 8)
static const uint8_t microstepcurve[] = {0, 50, 98, 142, 180, 212, 236, 250, 255};
#elif (MICROSTEPS == 16)
static const uint8_t microstepcurve[] = {0, 25, 50, 74, 98, 120, 141, 162, 180, 197, 212, 225, 236, 244, 250, 253, 255};
#endif

in both libraries.

Thanks for the feedback. I don't know of anyone else that has tried running that combination of shields.
