I took a quick look through the code and I think this block actually looks pretty good. There isn't anything I would've coded differently in the implementation VIs. The Configuration UI looks good from a functional perspective (all the values stuck between clicks on the Block, things grey out properly, etc). The Draw values all seemed to update properly on the block too. I'm glad that, even though you were new to LabVIEW, you've been able to be successful developing blocks for MINDSTORMS NXT.
Two small comments:
- I had to rename the folder within your zip file from "IIC Servo_Block" to just "IIC Servo". The Block Import/Export Wizard follows strict naming conventions and will not recognize your block unless the folder has the same name as your implementation VI.
- You might consider renaming "WriteSensor.vi" to something a little more specific to your block, like "IIC Servo_WriteSensor.vi". The reason being that LabVIEW/Mindstorms can't have two VIs of the same name in memory, so if some other 3rd party block developer has a WriteSensor.vi and a user has both blocks installed, one of the blocks will most likely be broken.
I haven't run the block at all to see if it really works, but it looks like it should. Good work!
