Havinig super frustration using LocoNet libary and IoTT Tinkerface - Arduino Interface Shield. In the ln_config.h file I uncommented the inverted TX and RX lines. Does anyone have a working sample sketch that uses the LocoNet library and the Arduino Interface shied?
The LocoNet library has 15 sample sketches. Obne way to get access to tehm is to search fort Loconet in the library manager then click the ... beside the name and you will see the following
Thanks for the reply. I am aware of the examples. I think I should have done explaining my issue. Root problem is that I am looking for someone that has successfully used the IoTT Tinkerface - Arduino Interface Shield.
Thanks again for your response.
perhaps you focus on getting just the receiver sorted out. that should identify the connections and whether inverted or not
Good idea.
Thanks
Steve
Hi
I got a sketch to work with my IoTT Loconet shield on a Uno but when I tried to use it on a Mega it did not work. On the Uno the TX pin in the sketch was set to 6. On the Mega I tried to set the TX to 6, 47 and 7 with no luck. I really want to use a Mega so I can get up to 9 turnouts with associated LEDs and pushbuttons. Otherwise I am limited to 2 turnouts on the UNO.
Any suggestions?
Sketch attached. I realize it can be edited down to remove serial print statements and unneeded code.
Thanks in advance`

Have been able to use the Tinkerface - Arduino Interface Shield on an Uno Arduino with success to work with LocoNet. When I try to use the shield on a Mega, . I set the TX pin to 47 in the code but it won't recognize any loconet commands. Is there something to do with the on board jumpers or something else in the code to add?
Serial or software serial on the UNO? MEGA has serial1, serial2, serial 3.
I have merged your cross-posts @trainman.
Cross-posting is against the Arduino Forum rules. The reason is that duplicate posts can waste the time of the people trying to help. Someone might spend a lot of time investigating and writing a detailed answer on one topic, without knowing that someone else already did the same in the other topic.
Repeated cross-posting can result in a suspension from the forum.
