STM32F4DiscoImuDemo

The STM32F4-Discovery board unfortunately has a design decision which prevents us from stacking it on the Element14 Ethernet board and using both Ethernet and the onboard accelerometer at the same time. This is unfortunate. However, with some relatively simple modifications, we can move one of the accelerometer bus lines to a different pin on the STM32, and use both peripherals simultaneously. The following steps show how to do this:

Step 1: cut trace from STM32F4 to the accelerometer SPI CS pin
