I'm having trouble getting my 5-inch FSK screen and camera to work. I've been trying to send instructions through an Arduino, using the same commands from your tutorial video, but nothing seems to happen. I've followed the screen configuration steps closely, except for the OS part since it's not needed when sending commands via the serial port. Could you provide some assistance? I would greatly appreciate any troubleshooting tips or guidance you can share to help me resolve this issue. Your insights would be really helpful as I'm eager to get everything up and running smoothly. Thank you!
