Hi i tried to perform the Chapter 18 from the StartingKit for RaspberryPi where LCD1602 Display is introducded. The cables are correctly linked and if i put the switch of the module to on then the LCD display is on but i can see no characters, pixels or anything else?! If i start the python script from chapter 18 also nothing changes (only very little changes of the contrast of the display are visible). What is wrong? Defect display? How am i able to check this? |
