MQTT and embedded cloud connection, WIFI modules, IOT AWS

• Design under Medical products standards, interfacing the product manager, QA, and clinical staff.
• STM32F4xx and STM32H74x FW design of 120GHz radar, for vital signs detection.
• Full responsibility for board bring ups, code porting, new features execution. Code reviews GIT, and more.
• Design the FW architecture for the first organization product based on STM32H742.
• HW drivers for SDRAM, USB, SPI, UART’s, GPIO’s, Analog PLL control, Amplifiers control, DC calibration, and ADC management.
• IOT and MQTT WIFI module protocol design.
• PC tools coding using C# GUI design

Design of STM32F205 device ARM cortex M3 using ROWELY Crossworks (CTL tasking library)
• Adding and improving features of a tachometer module for the vehicular market. The product connects to the car CAN bus, collects the events, and transmits them via GPS, 3G and WiFi modules. It is integrated into trucks, buses, private cars and more.
MQX OS : (Using Kinetis K70 CPU ARM cortex M4) using KEIL
• Serial FFS recovery manager module.
• BSP/PSP integration into new HW board, handling GPIO's, DDR/SPI/UART/I2C/LCD driver initializations.
• Running the application from DDR, and not from flash, not a trivial case for K70 and MQX.
• Writing UART API's, while modifying UART driver, to generate interrupt on idle.
• Writing code for peripherals modules, such as card swiper, barcode scanner, temperature sensor, ADC sampling,
• Writing/hooking a tester into the product code to be integrated with the engineering tester.
RTX OS: (using STM32F407 ARM cortex M3) using KEIL
• Modifying and improving code to handle I2C interrupt on a tag reader. Solving issues that caused clock stretching with the master device.
• Writing OS tasks to communicate via SPI with the master controller for different messaging purposes
• Writing code to communicate with ST bootloader commands for loading and programming flash from UART.

Bare Metal Design: MICROCHIP PIC16F: using MPLABX
• High endurance and robust keyboard, defining and developing a capacitive touch keyboard with 44 keypads, communication with master CPU, and with SW upgrade capabilities. Incorporating the development of associated bootloader. Sampling and shaping of signals from 44 keypads, cross talk elimination, and noise reduction. Using I2C/UARD, and ADC interfaces.
