О себе:
Projects I have been participating since 2016: 1. Electronic shelf labels system. Stand-alone electronic price tags with EPD screen. Base stations connected to the network via ethernet or wi-fi. Radio communication 2.4 GHz. 2. Online control and management of controllers from WEB-server The universal module connects to third-party equipment via modbus-RTU or modbus-TCP protocol. It collects data about controller’s state to the server database. Communication via ethernet or wi-fi. Communication channel via GSM for reserve. 3. Stand-alone cargo tracker with positioning via GPS or GSM, shock, orientation and temperature sensors. 4. Control of supermarket equipment in the adjoining territory Stand-alone devices with motion sensor placed on supermarket carts, base stations located on the adjoining territory and connected to server via GSM. Collection and analysis of sensors data to identify critical situations (removal of equipment outside the territory, attempt to put a cart in a car, etc.). 5. The system of control of penetration into the house Stand-alone shock sensors based 2,4GHz radio communication, shock sensors for wired communication, base stations, IP cameras. Fixing motion on sensors, recording video from cameras when detecting events on sensors, the ability to execute user scripts using equipment attached to the system. My role in these projects - components selection, prototypes manufacturing - equipment firmware and hardware development, database development. - systems operation algorithms development and testing - creation of a technical task for a project (hardware, firmware, server software) - management of software development and production of the experimental batch - projects installation Knowledge and experience: - programming languages: c, JavaScript, HTML, CSS, SQL - programming of controllers Cortex M0, M1, M4 and others: STM8, NRF51, NRF52, STM32 (TI SimpleLink CC3200 in study) - using of RTOS: Keil RTX - interfaces: SPI, UART, 1WIRE, - protocols: MODBUS, MQTT, development of own protocol of radio communication - programming under Linux (c, NodeJS, MySQL) - setting up a technical task for the development of hardware or software - prototyping, manual production or order for third-party production, spare parts logistics - programs debugging, work with logic analyzer, oscilloscope.
