Types of electronic devices - Embedded handheld devices with color LCD & touch screens, Data loggers, IrDA (infra-red) communications, ethernet (LAN) or Internet enabled devices, ultrasonic based SONAR, occupancy sensors, embedded computers/boards, GPS based Smartphone & Vehicle Navigation System, audio amplifiers, multi channel video switchers, key press counters, tilt alarms, , handheld computers .... etc.
Microcontrollers/processors - Samsung S3C24/25 series- ,Marvell PXA27/31 series-, Freescale i-MX21/27/31 series-, TI Omap Serials We have used almost all kinds of microcontroller peripherals in our projects like digital I/O, timers, watchdog timer, A/D converter, DAC/PWM, serial interface (UART, I2C, SPI etc), power management modes, USB controller, on-chip EEPROM, analog comparators etc - the list is very exhaustive. We can easily adapt to any system other than listed above.
Wireless technology - We have extensive experience in using wireless (radio frequency - RF or infrared - IR) for various applications. We have worked on embedded wireless Bluetooth & wireless LAN (802.11b) for wireless data transmission and controlling applications. We are aware about the FCC rules and complying with them. We have worked on readily available wireless (RF) modules & also designed the entire RF sections using discrete RF chips.
External Hardware - Real time clocks (RTCs), Radio frequency (RF) wireless transmitter / receiver & transceiver chips, GPS modules, GSM/GPRS modules, external EEPROM, Flash memory, SRAM, A/D converters, D/A converters, protocol converters, audio/voice CODECs, MP3 decoder etc.
User interface hardware -Keyboard, mouse, keypads, buttons, LEDs, LCD color modules , TFT color LCD panel, graphical user interface (GUI), touch panels etc.
