USB curve tracer for NPN transistors

Curve tracer is an electronic test instrument to analyze the characteristics of transistors and other discrete semiconductors. In this post we construct USB base curve tracer to analyze properties of NPN transistors. This curve tracer is build around Microchip’s PIC18F4550 MCU and it use simple Windows based GUI application to plot captured data of a

Happy Gecko ARM M0-based USB MCUs from Si Labs

Silicon Labs is producing ARM M0-based USB-enabled MCUs called Happy Gecko which aim to lower USB power drain and simplify USB connectivity. Adding USB interfaces to portable, battery-powered connected devices can double the application current consumption, says Silicon Labs. Happy Gecko USB MCUs have five energy modes enabling applications to remain in an energy-optimal state

Using Easy Pulse mikro with MPLAB Xpress board

Easy Pulse mikro is our new educational pulse sensor in a mikroBus form factor. Like our previous Easy Pulse sensors (Easy Pulse and Easy Pulse Plugin), it is also based on the principle of transmittance photoplethysmography (PPG) applied to a fingertip. The sensor consists of a pair of IR LED and photodiode to detect the

USB PIC Programmer

This page is dedicated to everybody needs to program a PIC (Microchip) device via USB port. Looking on the web for ready-to-use projects, I found a good one called Open Programmer, coming with several schematics, PCBs and Open Source code. The original link is http://openprog.altervista.org/OP_ita.html What concerned me was the need to mount, on the mainboard, a
