Hello, I must go to school so I will answer only to one part. I2C WRITE QUICK is used to detect the devices. It is simply a "probe" You will just issue bus transaction, Start cond, address, and you will wait if some device will confirm its presence. I'm not expert on this and I think then STOP is issued and thats all. It does not read/write anything just probing address if someone respond on this address. I will take a look to logs this evening. Regards Rudolf
