all-about-stepper-motors.zip - Stepper motors are DC motors that move in discrete steps. They have multiple coils that are
organized in groups called "phases". By energizing each phase in sequence, the motor will rotate,
one step at a time.,2017-08-05 03:24:39,下载1次
OPTO COUPLER Interfacing.zip - The following examples are typical circuits used for
reflective or transmissive assemblies. Consult the
product pages for specifications on the individual
assemblies you are using. The design should be
capable of tolerating a 25% reduction in the published
light current value (IL) resulting from short term thermal
effects and long term IRED degradation.,2017-08-05 03:21:56,下载2次

Lets' get physical
The natural place to start is the STK500. It is a very nice development board
for the AVR, reasonably priced (~USD79) and provides all the environment we
need to test some pretty real applications on the AVR out in the wild.,2017-08-05 03:19:50,下载1次
datasheet.rar - General Description
These octal bus transceivers are designed for asynchronous
two-way communication between data buses. The
control function implementation minimizes external timing
requirements.
The device allows data transmission from the A Bus to the
B Bus or from the B Bus to the A Bus depending upon the
logic level at the direction control (DIR) input. The enable
input (G) can be used to disable the device so that the
buses are effectively isolated,2017-08-05 03:12:38,下载1次
