Custom Device Driver Development • BSQUARE selected the Kionix KXSD9-1026 accelerometer as our example device – New Accelerometer on the DragonBoard – A driver was not available for Android – Will be made available by Qualcomm for the DragonBoard • Selected the Bosch BMA150 accelerometer source from the Snapdragon 8x55 MDP source tree as our reference device driver • Start initial driver modifications leveraging the reference driver
Custom Device Driver Development • Find a Similar Device Driver available in an existing Android Release – Since we were making an accelerometer device we took the source from an accelerometer used in a similar product to use as a starting point • The BMA150 • Taken from the MSM7x30 source • An I2C based device driver – In this new file, we changed all text of bma150 to kxds9 and appended the opening boiler plate
