Anup Bhattacharjee completed a successful 2-month internship developing drivers and functionality for wireless sensor network hardware platforms. He studied the TI MSP430 microcontroller and developed example programs. Anup also studied the WSN430 wireless sensor node board and developed example communication programs. He modified existing drivers for I2C, UART, and the TSL2550 light sensor. The modified drivers included automating the switch between I2C and UART modes as well as computing light sensor readings in lux units. Anup integrated the new drivers into Contiki and delivered all expected results on time and to a high quality.
