Loconet interface (Build your own) #19

Closed ATrain80 closed 2 years ago

ATrain80 commented 2 years ago

According to your schematics for the Loconet communication board, I have created an adjusted one. Since I do need only the Loconet communication and no separate loconet. However I have forgotten to connect pins 2 and 5 of the loconet RJ45 connector. For that I have created a wire bridge between the pin 5 and RXD. But at my DCC command station Digikeijs DR5000 the Loconet led TX keeps active. And I don't seem to have any proper loconet communication between the command station and my breakout board. I do not receive any commands on ESP32, and commands from ESP32 don't end up at the command station.

Can you please help me out? Thanks.

You pretty much rotated the connection lines. Please verify with the original schematics.

Thanks alot, I see what went wrong. The grove connector pin numbers are not the same as on your schematics. Pin 1 is pin 4, Pin 2 is pin 3 and vice versa. That explains the rotation of connection lines.

I will create a GND connection for pin 2 and 5, and connect my module correctly to the ESP32. Will give an update if it solves the issues.

Rewired the ESP32 to the Loconet PCB and connected the ground to pins 2 and 5 of the RJ45. Tried again Today, first data was not received correctly. But I have changed the UART speed in the library from 9600 to 16667. And it is working fine now. Thanks alot.
