在不替代8253的情况下解决其计数中的“翻转”问题

The Problem of “Turn” is Soved by the Method which the Chip of 8253 Don't Replace

本文介绍了用8253与V/F变换器构成高精度A/D转换器,在不替代8253的情况下,只要充分利用其三个计数器,就可成功地解决“翻转”问题,并用单片机实现之。

This paper introduces that A/D transister of using 8253 and V/F. No replace of 8253,We can sovle it’s "turn" problem in the single-chip microprocesser.
