parallel output การใช้

• There are also types that have both serial and parallel input and types with serial and parallel output.
• Each input bit makes its way down to the Nth output after N clock cycles, leading to parallel output.
• The SIPO ( Serial Input, Parallel Output ) block typically has a receive clock output, a set of data output lines and output data latches.
• Oh, there may be some goofy, black-box solution out there to convert parallel output to USB, but chances are it would cost an arm and a leg.
• This allows several binary devices to be controlled using only two or three pins, but slower than parallel I / O-the devices in question are attached to the parallel outputs of the shift register, then the desired state of all those devices can be sent out of the microprocessor using a single serial connection.
• In cases where the parallel outputs should not change during the serial loading process, it is desirable to use a latched or 74595 ) the serial data is first loaded into an internal buffer register, then upon receipt of a load signal the state of the buffer register is copied into a set of output registers.
