I would like to do the following but at compile time using #ifdef.
Is there a way to tell the compiler the deviceOS version.
the online compiler uses the “–target x.x.x” option, so how to we get that flag into the code?
if (System.versionNumber() < 0x001050000) {
Wire.beginTransmission(MCP23017_ADDRESS | i2caddr);
}
else {
Wire.beginTransmission(WireTransmission(MCP23017_ADDRESS | i2caddr).timeout(100));
}
Heres what I would like. (psuedo code)
#ifdef DEVICEOS < 0x001050000
Wire.beginTransmission(MCP23017_ADDRESS | i2caddr);
#else
Wire.beginTransmission(WireTransmission(MCP23017_ADDRESS | i2caddr).timeout(100));
#endif
Thanks
