SOFTWARE (FORTRAN, MATLAB, C/C++, Qt, C#) FORTRAN since 1979 for material and device simulations and signal processing. C/C++ since 1990, lately for SCADA and smart meter embedded code. I have launched a commercial smart meter in the utility space based on Qt on an Arm9, porting to Sitara. PIC18, dsPIC33, and TMS320C280x with FreeRTOS and bare metal and application level (user space) Linux embedded on Samsung S3 and Sitara chips. EMBEDDED HARDWARE PIC 18 smart sensor with I2C connectivity and 4KV surge protection. dsPIC33 smart sensor interrogator with same immunity. Smart meter designs. UL61010-1 and IEC61000-6-5 compliant RS485, I2C, and power supply design for substation electronics. RF Wireless, passive sensors at 434MHz and 915MHz. SAW and BAW filters, resonators, and sensors. Oscillators. EN300220-1 and FCC Part 15 transmitters. Mixed signal cards with TMS320, dsPIC, and RF (200-1800MHz). Smart sensors. MISC General knowledge from materials to systems.
