Hello,
I've got a hardware setup and question very similar to the one posted by user amundsen, on November of 2011.
In my setup I've a Bluetooth Mate Gold connected to the TX/RX of the IMU, but find myself needing to incorporate a pushbutton to the hardware. There are no GPIO jumper-ports on the Razor, the TX/RX lines are taken---can I use the MOSI/MISO ports in some way to make this happen?
This is part of an urgent project, any and all help is appreciated. Thank you in advance.
