AfroEsc i2c commands

Hi, I just bought a couple of AfroEsc (20 amps).. I'm trying to interface one of them with a PIC microcontroller.
Could somebody clarify the startup sequence for the ESC?

I've tried the following:

Send 0x50 on the bus and wait for an answer. I get NoAck seen on my logic analyser.

From what I've understood the device address is 0x50 by default and I should send a throttle byte after "connecting" with the specific device.

Any one done this?

regards / Christian

Ok, got contact with the ESC on address 0x52.

The Esc arms and plays a the wanted melody after sending 0x00 and the green led lights.

However the motor wont spin after sending a throttle value?

Anyone experienced that?
