TDA4VM: q1

Lee Jiankun
Prodigy 60 points

Part Number: TDA4VM

The serial port of the TDA4 processor is in a loop phenomenon. When the TX and RX of the two boards are connected, there will be continuous high and low levels instead of the intermittent high and low levels set by the program. Can anyone help?
