Realtime Control Microcontroller Development

I need an experienced microcontroller developer to create a realtime process control system using a state machine. This system will be responsible for: - Sequential task execution - Event-driven responses - Timed operations The solution will run on a realtime operating system (RTOS)... (Budget: $3000 - $5000 USD, Jobs: Debugging, Embedded Software, Embedded Systems, Microcontroller, RTOS)
