模拟电子 精密DAC和看门狗提高模拟输出安全
Abstract: Using a DAC and a microprocessor supervisor, the system safety can be improved in industrial controllers, programmablelogiccontrollers (PLC), and data-acquisition systems. The analog output is set to zero-scale (or pin-programmable midscale) when amicroprocessor failure, optocoupler fail ...

NAME Control_AT24Cxx
This collection of routines allows an AT89C2051 microcontroller to read
and write the AT24Cxx family of serial CMOS EEPROMS. This version of the
code is compatible only with the AT89C2051 due to the location of the
data buffer and stack in RAM. The code may be modified to w ...
