The RS232 standard was born before RS485, but there are several deficiencies in RS232: The signal level of the interface is higher, to more than 10 V, the use of improper easy to damage the interface chip, level standard is also incompatible with the TTL level. Transmission rate is limited, can not be too high, generally to zero or zero bits per second (kb/s) to the limit. The interface uses signal lines and GND to form a common mode of communication

Surrounding environment:System environment: Win7 64 positionSoftware platform: Multisim 12.0Objective:Just graduated, but the mode of knowledge also forgot almost the same, coupled with their own want to engage in hardware design. Let's say it's just a reading book. Do not practice, or eventually feel shallow. As an interest to learn the mode of electrical, simulation simulation.Multisim MCU less, take 51来 practice practiced hand. Build 51 single-chip

Today in the group there is a Netizen mentioned 51 single-chip computer using printf why the compilation passed, but no effect. Here to share my notes, the experiment itself does not make much sense, mainly to record 51 how the single-chip microcomputer should use the printf function.Experiment Name: Serial communication single chip microcomputer and PC calculati

MT8389 is a stranger to everyone, but if I say MT6589, I guess everyone understands it. In fact, MT8389 is a branch of MT6589, and a clone branch makes it clearer, is MT6589 high-consumption version. It can also be seen as the same CPU. I think it is necessary to popularize the basic knowledge of MTK CPU before explaining MT8389, because the CPU development of MTK has a great continuity, for example, the smartphone chip contains the function mobile ph
