  • Compilator C for MCS8048

    Embedded Systems & Microcontrollers
    For IC MCS8048 at that time (and today) there was no C compiler.
    The task was to write a compiler and develop a few stages on it on MCS8048.
    The compiler used the recurrent drop method and issued the result in the form of an assembly code or binary file. With the help of the compiler, two devices were developed.

  • IP-telephony on a specialized router

    Embedded Systems & Microcontrollers
    The MIPS router contained 4 MB of flash and 32 MB of RAM. The OpenWRT operating system in the packed appearance was contained in the flash, while working was packed in RAM.
    OpenWRT has a SIP server and a microphone/dynamic driver.
    With the help of the device, it was possible to talk through the IP-telephone.

  • Pressure sensor with support for HART and Modbus

    Embedded Systems & Microcontrollers
    The sensor measured the pressure, repaired it in any measurement unit from 20, stored the calibration coefficients in the flash, recorded the measurement archives in the external EEPROM, displayed the information on the RKI. HMI allowed to select measurement units, set measurement limits, stop/stop archives, a total of about 15 functions.

  • Multi-Function Timer at AT8051

    Embedded Systems & Microcontrollers
    Timer replies time, loses polyphony.
    The complexity was that the IC had no built-in SHIM. Furthermore, the frequency of MK is 1MHz. Polyphony is synthesized with DDS. The data for the melodies were stored in the external EEPROM in packaged form. It was necessary to read the data in time, dispack them and get into the SIM software method.

  • Camp of the Prietary Protocol

    Embedded Systems & Microcontrollers
    The information is collected with 8 UARTs pars and is sent to the console (file). Packages from the port arrive at random time.
