...According to table 6.5 and 5.3 in this pdf file i need to place a 124 k resistor between pin 4 and 5 to enter the right mode. Can anyone confirm this? It seems awfully close to the 121 k used for TTY converter on the I9000, but could that be because the I9000 wasn't really designed to be OTG compliant?
I wonder if somebody was able to use the resistor combinations RID_AUD_REMOTE_S*_BTN to control some of the standard MP3 players on Galaxy S2.
Second is does somebody tried to apply the corresponding voltage values with a DAC.
I'm asking because I think of making a Bridge between my Car-CAN.BUS and the RID-Pin to be able to control the S2 via the Steering Wheel Switches. All I would then need is a 4-5 pin micro translating the Steering Wheel Messages into DAC-Values in car/dock Mode.
That would be cool:
Just stick the USB-Cable into the mounted S2, Car-Audio goes into AUX-Mode (automatic) and shuffling through the MP3 collection without taking hands of the Steering Wheel while the S2 is charged.
What do you think about that?
