Major: - Improved UART Timeout: Apparently, the UART data Rx/Tx is quite unreliable (especially under motor load) leading to very often out-of-sync issues. This change allows to reset the DMA more often, leading to a faster re-sync of the UART transmission and thus avoiding UART timeout Minor: - added #define MPU_SENSOR_ENABLE to allow to enable/disable the MPU6050 sensor and save code size if the sensors is not needed - fixed the orientation in the Processing sketch - updated ReadMe
