Application for door control system;Responsibilities: Full cycle from designing the circuitry of door control units to writing a program. There are three devices in the project. Door control unit, a device that receives data via RS485 with a self-written protocol to maintain security and fast transmission speed. The project used Freertos for a master working with 32 slave blocks. Via the same RS485 (uart), the master’s control logic is written to the eeprom.

There are three devices in the project. Door control unit, a device that receives data via RS485 with a self-written protocol to maintain security and fast transmission speed. The project used Freertos for a master working with 32 slave blocks. Via the same RS485 (uart), the master’s control logic is written to the eeprom. The block has protection against reading the firmware and an additional block was implemented on an esp32 which is connected to ethernet and via TCP commands are received from the block on the SOC (imx6) on which Linux and a java Spring application are installed under the Yocto build system. The SOC provides a React interface for showing control events and tracking people entering through the doors. The Mifare Desfire card reader is installed and written in the slaves, which is entered into a protected mode that protects against reading the key card values. Java Spring includes raised https with csrf. This ensures security at each level, a good browser interface and a black box of events. For to provide centralized updates for ESP32 and STM32, we have written our own bootloaders, which allow you to centrally update ESP32 devices via tcp. STM32 is updated via CAN.Keywords: STM32, C++, Freertos, ESP32, bootloader, TCP, Yocto, Java Spring, react, redux, postgre Show less

Urban Transport Information System (Embedded developer + full stack developer);Responsibilities: This work is divided into three devices. Device on SOC for Linux buildroot build system. The device is a touch screen monitor for the driver. When connecting Linux, you need to rewrite the Linux kernel modules for touchscreen to be compatible with imx6.

Device on SOC for Linux buildroot build system. The device is a touch screen monitor for the driver. When connecting Linux, you need to rewrite the Linux kernel modules for touchscreen to be compatible with imx6. The display interface program and driver monitor behavior logic are written in C++ QT. The program is located in a black box located on a USB drive. Because The entire file system associated with Linux (uboot, linux) and the running QT application is in read-only mode to ensure fault tolerance during long-term operation. The application provides a graphical interface for configuring devices connected to the CAN, and an interface to an external box that stores values which get from the another devices in the CAN transport network, processing and storing ~300,000 events per second. Monitors of different versions were made on dual-processor modules (imx6, nvidia jetson).The second device is a control unit for an asynchronous motor, transmitting its state and control interface via CAN (controlled with a monitor).And the third device blocks door and lighting controls. Engines (infineon xe167) and control units (dspic) are updated via CAN; each device has its own bootloader written.Keywords: C++ Qt, uboot, CAN, ADC, DMA, imx6, nvidia jetson, infineon, dspic Show less

In order to set the correct settings for where to write, the logic was as follows: the recording control module using Lightweight HPS-to-Fpga receives data from a Linux kernel module that allocates a large block of coherently located memory. To ensure that you can stream a date without missing a date, the module that receives the data writes cyclically, filling frames of a certain length, and when it overflows, it starts writing again. This solution made it possible to write an application in user space that read the current filled frame (Lightweight HPS-to-Fpga), packaged the frame into png and sent it to the server via TCP.Keywords: Verilog-hdl, System-verilog, AXI bus, U-boot, linux kernel module (CMA), C++ tcp, Cyclone V Show less
