Based on PIC18 monolithic integrated circuit
Wednesday, December 2nd, 2009 at 02:04 | No commentsCategories: Embedded systemShort Content: 1 introduction RS-485 is an electricity interface specification, it has defined one based on the list to the line of balance multi-spots, bidirectional (half-duplex) the information link, only makes the stipulation to the connection electrical specification, but does not involve the connector, the electric cable or the agreement, based on the user may establish own high-level communication protocol, from that time's point of view is one relative economy has the quite high noise abatement relatively high transmission speed transmitting ... -
Realizes the high resolution frequency meter
Sunday, November 29th, 2009 at 21:32 | No commentsCategories: Embedded systemShort Content: The abstract introduced the high resolution frequency meter's one kind realizes the method. This method is develops the platform based on the PICC higher order language. Uses the PIC16F87X monolithic integrated circuit, this plan has the principle to be simple. The perform reliably, the resolution high characteristic, uses when this method survey low frequency frequency most little may obtain 8 significant digits. 1 introduction Along with electronic technology's rapidly expand, take the monolithic integrated circuit as the control core's ... -

Based on PIC16F877A square-wave signal generating device circuit design_PIC, 16F877A, square-wave signal
Saturday, November 28th, 2009 at 20:18 | No commentsCategories: Embedded systemShort Content: In the digital circuit system, the square-wave is the supply oscillator which uses frequently, has the very widespread application scope. In the ordinary circuit design, uses 555 timer constitution multivibrator to produce the square-wave signal frequently, although is quite simple, but the frequency accurate precision is not high, if produces the different frequency square-wave signal, the replacement resistance and the electric capacity are also quite troublesome. Based on this starting point, this article uses the monolithic integrated circuit ... -
