  -Developed embedded software for a clocking board on a portal linear accelerator system. The role of the board was to synchronize the firing of the linear accelerator with the triggering of the detectors for optimal x-ray image capture (C on FreeRTOS, MQTT). -Adapted a WinCE7 BSP to support an Intel Atom-based single-board computer. Included writing a watchdog driver, GPIO driver and configuring the OS. -Developed embedded software for a clocking board on a portal linear accelerator system.
