Embeeded Electronics Designs and 3D Modelling

I am an expert designing electronic projects. I typically use 8bit and 32bit microcontrollers. I excel in designing low cost, low noise and low power systems. I am an expert in C. I enjoy developing PC applications using Qt. I can run electrical simulations in LTspice and SimulIDE. I use OrCAD and KiCAD for PCB design. I also have a lot of 3D modelling experience, particularly to enclose my projects. I typically use these microcontrollers: AVR, PIC, PIC32, MSP430, STM32 Cortex M3/M4

This application was developed using the Qt Framework. The application connects to an Xscope device using the LibUSB library. The data is displayed at a high frame rate, and the user can control all the parameters of the oscilloscope.

Source code: https://github.com/ganzziani/xscopes-qt
XScopes PC Interface using Qt framework
The XScopes are a combination of many electronic instruments: a mixed signal oscilloscope, an arbitrary waveform generator, a logic analyzer, and a protocol sniffer.
The Xprotolab and Xminilab can be plugged directly on a breadboard, which can greatly simplify diagnosing your circuits. The portable versions have a case and a battery.
The devices con connect to a PC software which was developed with Qt. The Xprotolab was awarded as one of the 100 Hot Products of 2011, by the EDN magazine.
