He has written low level drivers (SCSI, GPIB, Serial, I2C, SPI, SSI, ethernet, 1553, VME, PCI, MBus, SBus, USB, ISDN.
He has written mid-layer "HAL" type interface software (ie. to connect low level drivers into upper layer API's). For example: Windows serial (RS-232) API layer to allow remote control IR hardware (coming in over RS-232) to interface to a GUI on a DVR (Digital Video Recorder).
He has written Application Layer software on numerous platforms. For example, Test software under Solaris for ethernet (TCP/IP) testing of a SBC (Single Board Computer). Automated testing software under Windows to allow DVR's to be tested in a automated MFG environment. Application Software to act as Linux development kits (ie. GUI development kit, embedded development kit, software development kit, etc..). Test code under VxWorks to validate ethernet interface (TCP/IP) and Shared Memory interface between SPARC processor and Intel i860 slave processor. GUI under FreeBSD to act as a Control GUI for a Internet Compression Router (which I also developed). The GUI also displayed connection statistics such as compression ratio, bandwidth being used, error statistics, etc..
Very good experience writing Digital Signal Processing drivers and application code under Texas Instruments DSP/BIOS O/S and Code Composer Studio. He has written low-level drivers and also application code for numerous projects. For example: SPI, I2C, UART/McBSP, SSI codec, PCI, DAC and A/D (ADC) low-level drivers. Wrote full control application to interface to Mgmt GUI over ethernet (TCP/IP). System was a Fiber-Optic Biochemical Sensing Controller using Fibre Optic "Lockin-Amplifer" approach, DDS and Quadrature demodulation of audio frequency tones.
