why didn't you say that at the beginning!
I did..you didn't understand. 
well in fact I changed nothing, I only commented those IIC_wait-functions.
So you DID change something...you destroyed the timing of the I2C bus
If I uncomment them the SCL will be again 30kHz
Yes but it will be working properly.
When you say drivers...do you mean the AS1130 chips?
You will know if the chips are dead if you do what I suggested above AND you don't get a response from the chips (ack).
* note to self....I should have been a dentist...this is just like pulling teeth.... :grin: *
