After the second line is over, press Enter to save and exit. 3）Create three folders, ICON, LIB, and PHOTO under the GUI folder LIB folder---used to place font files, the naming of font files conforms to XXXX.
3.3.2 Burning steps 1) Before burning the picture font library, make sure that the bottom layer has been burned. You can open the configuration debugging interface to connect to the code file to observe whether it can communicate. If it fails to communicate, first reset the motherboard and try again. 2) After adding the files to be burned in the U disk according to the second step, connect it to the USB port of the motherboard, and then power on the motherboard.
Figure 2 Schematic diagram of external controller connection 6.Common troubleshooting 1. The connection between the display case and the grounded metal part should have a low impedance value. It is qualified by the following test. When the transient interference is injected, the voltage drop is measured between the controller case and the grounded metal parts. It is required that the voltage Umax on the case should not be greater than 0.
FCC Statement Any Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) This device must accept any interference received, including interference that may cause undesired operation.
