The frequency of the traditional general is formed by discrete components lap. With large-scale application of the SCM, SCM in frequency measurement also be used more and more. In this issue of the use of ATMEGA16 This low-power, high-performance microcontroller, the stability is better, faster and more accurate calculation accuracy, and promote industrial production and affect people's work and study. 摘要 I
