QuadratureTech

20+ years of embedded software, bare-metal firmware, and hardware design and development skills.

Design the whole path from concept to finished product.
'Hands-on'​ practical approach, able to work unaided on own initiative.

Embedded Software/Firmware

Time-critical systems measure and control in a real-time, multi-tasking environment.

Bare metal code design and maintenance in C/C++ and assembler on hardware with no underlying operating system. Can utilize RTOS if preferred.

Code is written me from scratch with microcontrollers listed in the 'Embedded Hardware'​ section below.

Maintain existing code written previously or presently in a team (waterfall environment).

LCD GUI design and development. Driver development for IC’s.
I2C, SPI, UART, CAN Bus, ADC, DAC, RTC, RS232, RS485, USB, Ethernet, Modbus, TCP/IP
