本帖最后由 老冏 于 2020-9-24 14:55 编辑Hi, everyone,
I'm using DMT10600T070 to show up text, by using UART download tool change VP value
this is my GUI:

please help me to figure out this, thanks It is very likely that the communication is not successful. Use the serial port 2. Under the wiring check, connect RX2 and TX2. The communication and power supply share the same ground. The level of the serial port 2 is 232, and communication with the computer does not need to be transferred. To check whether the communication is successful, you can send a command: 5A A5 04 83 000F 01, whether it will return the version number.

any other idea, please?

and now another question comes up,
I don't see any 232-TTL switch on my board, not even a jumper or something
yet I don't know how to initialize other UART port too,
Do you have refer tutorial link to me? That person’s problem is different from yours, the screen is different, and the wiring method is different. The suggestion for you is to change a 232 to USB adapter board, or 232 on the screen leads to a DB9 header to connect to the computer. 沃特玛贞帥斯基 发表于 2020-9-24 19:53
