Android hardware dev kits?

I'm faced with the task to write a driver for Android (OS 2.3 and 2.4) to interface with a sensor chip over either SPI or I2C.

The device is intended to be used in Android smart phones eventually, based on either the Intel Medf开发者_运维百科ield or the Qualcomm 8 series platforms.

I assume that I don't have to worry about actually writing the SPI or I2C driver myself, right? Do you know of any current SPI or I2C drivers for Android I could use?

I will also need find a hardware development kit which allows me to access the SPI or I2C bus. Do you have a recommendation where I could find a suitable kit, which is representative of the hardware typically found in a current Android smart phone?

Don't know specifically about what you're developing, but have used a freescale hardware dev kit in the past for similar work. They have it.
