Application of LED Display Circuit

 

 

 

There are 8 LED Displays of Board ET-STM32F130 and 

the circuit that drives LED is connected as Source 

Current. It uses Buffer No.74HC244 to drive current into 

LED and then uses signal from Port PB[8..15] to run. In 

this case, it runs with Logic “1” and stop running with 

Logic “0”. User can select to ON/OFF operation of Buffer 

No.74HC244 by setting Jumper J17 as shown in the picture 

below.
