ENIGMA Distinctive
Excellence Winner. October 16, 2007
"The Microchip 16-Bit Embedded Control 2007 Design Contest was a great opportunity for the world’s most talented engineers to learn more about Microchip’s 16-bit microcontroller and digital signal controller (DSC) families. The challenge for each entrant was to incorporate any of Microchip’s high-performance, versatile, commercially available 16-bit microcontrollers or 16-bit DSCs in an exciting, novel design. With a chance to gain international recognition and win a portion of $15,000 in cash prizes, there was no shortage of enthusiasm for participation. Designers from all over the world stepped up to the challenge and delivered well-designed projects for the judges to evaluate. After weeks of closely studying the entries and judging the projects on their technical merit, originality, usefulness, cost-effectiveness, effective use of on-chip resources, and effective use of bonus parts, the judges tabulated their scores and submitted them to the contest administrator. The results are now final, and we’re proud to announce the winners." Circuit Cellar Magazine, December 2007 Letter from Circuit Cellar to Carlos Cossio dated December, 2007: Dear Carlos, Thank you for participating in the Microchip 16-Bit Embedded Control Design Contest, and congratulations for being selected as a Distinctive Excellence recipient. The contest was a great opportunity for the world's most talented engineers to learn more about Microchip's 16-bit microcontroller and digital signal controller (DSC) families. The challenge for each entrant was to incorporate any of Microchip's high-performance available 16-bit DSCs in an innovate design. We felt strongly that there were considerably more first-rate projects entered in this contest than could be satisfied with the available prizes, so we designated a special category called "Distinctive Excellence" for some of the more noteworthy projects. Your project is definitely worthy of this honor. In addition to your check, we would like to present you with the enclosed certificate. We want you to know that we recognize the considerable amount of thought and effort that you put into designing your project and preparing your entry. You should be proud of this major achievement! In the coming days, your project will be posted on our web site as an example of excellence in design. And, as always, we look forward to working with many of the contest entrants to publish related project articles in Circuit Cellar magazine. Thank you for participating in this successful contest. We hope to see another of your entries in one of our upcoming contests! Regards, C.J.
