TX Y RX

Hola :: ENGLISH ONLY on Forum



Gracias


Gauge is 360 degrees,  I cannot replicate this result.  270 should point to 6:00 vertically.


Yes you can use a PIC with two wires for RX/TX.  You will be responsible for coding the serial requirements


See the Nextion Instruction Set for formats

You need to transmit z0.val=270 followed by three bytes 0xFF 0xFF 0xFF


Text Commands sent to Nextion require termination, this termination is three bytes (0xFF 0xFF 0xFF). In hexadecimal notation the byte value is 0xFF. In decimal, the value of this byte is 255. Termination of a command requires three such bytes.

z0.val=270  (+ Termination 0xFF 0xFF 0xFF)


My Spanish is no good, Google Translate making errors.

I will make a guess, but probably guess  wrong.  Question needs to be in English.

The next commands you may be looking for is

get t0.txt yyy

get z0.val yyy



HelloI can update a variable via the serial port every second.
example t0.txt="123"ÿÿÿ passing one second t0.txt="124"ÿÿÿ

simulated , if I could do it.and with the physical screen , I can not
help me, please

do

   {

   message = myNextion.listen(); //check for message

   if(message != ""){ // if a message is received...

   Serial.println(message); //...print it out

   }

  }while(not(message != ""));
