Hello
I am trying to use my radio using a nextion screen.
The thing is that the interface is quite simple except for the frequency control using arrows
It just needs to sens simple comands such us XBA for Am, XBU for upper side band and so on
I had to make a ttl to 232 adapter.
Now radio is connected to the interface but… i have to press the keys 2 or three times in order to send the command.
The nextion Only uses the tx cable so inplugged the rx into an arduino to see on the console if i get an error message. The thing is that apparently it only gets the confirmation code and no error, that is the previos clics make no actual “contact” with the radio
Here is an example of the key “CW” MORSE band
b3.bco=65504
b3.bco2=23770
b3.pco=0
b3.pco2=65535
b0.bco=23770
b0.bco2=65504
b0.pco=65535
b0.pco2=0
b1.bco=23770
b1.bco2=65504
b1.pco=65535
b1.pco2=0
b2.bco=23770
b2.bco2=65504
b2.pco=65535
b2.pco2=0
print “XBC”
printh 0d
printh 0a
mode.val=3
Any hint??
Thank you
