LCD Screen Remains Blank on BeagleBone Black with HC-SR04 Ultrasonic Sensor
hello guys, based on my previous question on developing an obstacle detection system using a BeagleBone Black running Embedded Linux using HC-SR04 ultrasonic sensor to measure distances and displays the measurements on a 16x2 LCD screen. am encoutering a situation where the LCD screen remains blank and does not display any readings, and i have verified the lcd is powered correctly, i have also checked lcd initialization 
python 
lcd = CharLCD(pin_rs=LCD_RS, pin_e=LCD_E, pins_data=[LCD_D4, LCD_D5, LCD_D6, LCD_D7], numbering_mode=GPIO.BOARD)
python 
lcd = CharLCD(pin_rs=LCD_RS, pin_e=LCD_E, pins_data=[LCD_D4, LCD_D5, LCD_D6, LCD_D7], numbering_mode=GPIO.BOARD)
but still my lcd screen remains blank
