Thanks PaulS,sry i`m a noob. Can you please show me on the attachment which pins i should use for user serial1? TX1 and RX1 i have connected.
Not according to the picture you posted. That picture shows the orange wire connected to pin 14 (TX1) and the red wire connected to pin 1 (TX0).
I change the red to pin18 and the orange to pin19. But same effect.
Which wire i must switch and to which pin?
Sorry that I ask so stupid
Re-read reply #9, paying particular attention to the last line.
Or you mean i should change the code ?
