Hello, I tried to change the baudrate of this serial LCD. But failed every time. The initial baudrate is 115200. So with 115200bps, I sent 0x7C 0x07 0x03 commands for 19200bps. And then changed my speed to 19200bps and sent next commands. But gabage on the screen. Altenately with 115200bps, I sent 0x7C 0x07 0x33 commands for 19200bps. And then changed my speed to 19200bps and sent next commands. Same gabage. It means the baudrate was not changed. I was wrong? What is the truth?
