Hi, I want to test the IOT internal interface with serial port node. I tried to send a "HelloWorld" string periodically via serial out node, and used serial in node to receive the string. The two pins GPIO Rx and Tx (ttyS0, pin1 and pin2 of X11) are connected physically with a wire. The flow in red node is attached, and the configurations for both serial in and out nodes are the same, which is also attached. This is a very simple UART driver test, but there is no output in the debug window of node red. Can you help to locate the problem ? ------------------------------------------------------------------------------------------ AttachmentUART test.zip (603 Downloads) |
