Changes

v1.7.3

• Corrected Xojo method signature for SPIDataRW to use CString to fix compile error.

v1.7.2

• Corrected Declare method signature for SPIDataRW so that you can actually get the output.

v1.7.1

• Setup, SetupPhys and SetupSys now also initialize PinDict.

v1.7

• Commented out WiringPiISR method as it makes its callback in a pre-emptive thread making it unsafe to use with Xojo.

v1.6

• Added WiringPiISR implementation and related constants (thanks to Bjorn@Einhugur).

v1.5

• Added GPIO.Cleanup method
• Added GPIO.SoftPwmCreate method
• Added GPIO.SoftPwmWrite method
• Added GPIO.RGBLED class
• Added GPIO.Servo class
• Added GPIO.SoftToneCreate method
• Added GPIO.SoftToneWrite method
• Added GPIO.Version property
• Added GPIO.LCD class
