A tribute to Nikola Tesla - 2

อังคาร, 07/20/2010 - 13:50

In 1887 Nikola set up his own company, and was able to lodge two patents for applications related to the induction motor and polyphase AC power systems. These achievements gave a certain notoriety to Nikola, who was invited to speak at the American Institute of Electrical Engineers; he was lucky, since at that conference was present also George Westinghouse, owner of a growing electrical company.

Calibrating the eQADC module of the Freescale MCP5510 Microcontroller Family 1/2

จันทร์, 05/24/2010 - 13:50

eQADC stands for Enhanced Queued Analog-to-Digital Converter, and this is the name of the ADC module integrated in the MCP5510 Family microcontrollers. As a hardware engineer, I was more used to the simple 10bit ADC which are usually found in lower end 8-bit microcontrollers (like the PIC18 series, for instance). The first time I came across a MPC5517 from Freescale, however, I was baffled by the need to calibrate the eQADC module, which would otherwise be affected by large errors.
