Lets say I wan't to hook up sparkfun.com's sensor-du-jour to my
openmoko Neo1973, (and later Freerunner :-).
(i.e. something like
http://www.sparkfun.com/commerce/product_info.php?products_id=7918)
Ok, lets go:
I2C Access: Check!
(on Debug Connector pin 18 and 19 and on Testpoints, as documented
in http://wiki.openmoko.org/wiki/Neo1973_hardware#Debug_Connector )
Free I2C Adresse: Check!
(http://wiki.openmoko.org/wiki/I2C)
Power: Not Good.
Where can I take power from ?
Is there a testpoint or pin of the debug connector that is
connected to the voltage regulator chip and where it is save to draw a
few milliamps ?
(typically, such a mod does not need much power) Something that is
switched off when the phone goes to standby would be ideal.
Sofar I have not found any information about such a thing in the
Wiki, which might explain why there have been so few Hardware Mods
till now.
As usual, any comments welcome!
Cheers,
Thomas
