In creating an electronic device using a microcontroller, we often faced with shortages in ports for line I / O or LCD viewer. In the article series LCD with 74HC595 Serial To this there is a solution to overcome the lack of ports or pins of the microcontroller is to convert the parallel bus system such as the LCD into a serial sequence To Serial LCD with 74HC595 this. The series of LCD Serial To change the system of parallel bus into a serial LCD IC 74HC595 premises. 74HC595 IC on circuit Serial To this LCD is a digital IC that it functions as a serial to parallel shift register is equipped with a latch. With the functions of the IC 74HC595 parallel LCD bus system in enter in great numbers have turned into a serial of microcontroller and be a series of Serial LCD with 74HC595 for this. Now with a range Serial To LCD with 74HC595 for the microcontroller is expected no more stories lack the pin / port of the microcontroller in the manufacture of electronics equipment.
The series of Serial Line Specification For LCD with 74HC595
Hopefully helpful and inspiring in the case of lack of lane / port microcontroller to the viewer data.
- Clock as input clock of the microcontroller
- Data as input data for the LCD display
- Enable is the read data selector LCD mode or Disable
- LED is a path to control LED LCD baground
- Potensimeter on the LCD serves to adjust the LCD display bright
