[Question]Hex Command

nexium

I just joined this forum, sorry if it's in the wrong room.

i have problem with HEX command for screen DMG12480C068_03WTC

With the help of a sales engineer, the speaker can go into the off state to beep
the hex is 5A A5 07 82 00 80 5A 00 00 35
but I can't make it on even with HEX 5A A5 07 82 00 80 5A 00 00 79
can anyone help for correct hex?

2nd question, can DWIN screen send HEX when the screen is touched and wake up (from sleep state)
the goal is to let the MCU know when the screen wakes up

3rd question
can DWIN screen send HEX when enter sleep mode?
The goal is to let the MCU know when the screen is sleeping

Thank you, I hope someone can help me with my problem

1. try this command 5A A5 07 82 0080 5a 00 00 3d

2. you can send a 0x00d4 serial port screen operation simulation to the screen to light up the screen

3.mcu can read 0x31 address to obtain the current brightness value of the screen

thanks Lreamy for your response  

1.5A A5 07 82 00 80 5A 00 00 3D not working, beep sound still off

2. I mean when the display is in a sleep state and when touched with a finger, the display wakes up and when it wakes up, can the display send a wake-up state HEX?
so display sends HEX to MCU wake state

3. 3. so my display configuration is 10 seconds display sleep, when the display goes to display state can the display send HEX to MCU not MCU check the display

thank you for your help

1. I tested that this command is normal, and the buzzer can be turned on and off.

2. if the screen is required to actively send instructions to MCU, it is required to write code in the screen
