ZEE Powered Systems

ERS's team of software and hardware engineers has proven the effectiveness of ZEE^TM technology in applications that include the Energy Monitoring and Control Server system (MCS), ZEE Network^TM and aerospace controller.

Hardware Targets

We have proven experiences in MSP430, M68K Family (eg. 6805, 6812, 68xxx, ColdFire), Atmel, Z180, 8051, PIC, and a few others, especially 8-bit and 16-bit microcontrollers.

Software RTOS (Real-Time Operating Systems)

We are skilled at writing code and debugging applications for almost any real-time operating system, especially for non-commercial RTOS. If starting from scratch, one of the many versions of Embedded or Real-Time Linux is often our first choice, however we can also build software for systems employing VxWorks, VRTX, QNX, pSOS, uCOS, and many other less common RTOS.

Real-Time Issues

We solve any real-time problem using practical precise advanced scheduling techniques. We can implement rate monotonic algorithm, guaranteed soft real-time algorithms, priority inversion avoidance, interprocess communication, interrupt handling, timing error detection and handling, aperiodic servers, etc.

Device Drivers

We can build device drivers for any of your sensors and actuators. This includes both analog and digital inputs and outputs, serial busses like I2C, embedded networks like CAN, and wireless communication using IR or RF.

Software Engineering

We follow a proven methodology that includes process life cycles, specifications, system decomposition, architectural design, detailed design, critical design reviews, code reviews, testing and debugging.

Complex Debugging

We find those most elusive errors in your code, including glitches that only show up once every few days or weeks. We can identify and fix timing errors, synchronization problems, priority inversion, memory corruption, race conditions, hardware bugs, and other difficult to find problems.
