motor shield address
I soldered a jumper across A4, leftmost bridge, on the motor shield. Is 0x76 the correct address? The motor isn't responding.

2^4 is 0x10 plus the base address of 0x60 = 0x70.

Re: motor shield address
isn't that the "all call" address of the motor shield? I'm using two motor shields, the first uses the default address.adafruit_support_bill wrote:2^4 is 0x10 plus the base address of 0x60 = 0x70.

Re: motor shield address
Yes. 0x70 is the all-call address for the pca9685, so you should select a different. one.
