more i2c and mcp23017

working with the i2c commands is a bear!

would you care to provide some code to demonstrate a i2cread/write command that exhibits some problem

I find it always works as documented .


I suspect that you have no idea of what the centipede library actually does behind the scenes and that
you are attempting pbp code based on that total lack of understanding. maybe if you posted some code
help would be offered all we have seen so far is just totally wrong.

good luck with your endeavours on the Arduino forum , they just love posts with no code

I also found that they get arsy if you give them too much. I didn't get much joy from the three arduino forums I posted on when porting my thermostat code to the platform. They also don't provide code for you if you're stuck, they expect you to work that part out when they've told you what to do, and if you are new to the platform and still find the syntax strange.

I found the guys on this forum a lot more friendlier and supportive. It's just a shame that PBP lacks the native support for most modern things - but I2C is one of the basics and I've never had issues when using it to talk to LED driver chips etc.
