Troubleshooting assistance #20

Closed hammyMarc closed 3 years ago

Build: Pi 3b+, MMDVM Jumbospot, pimoroni fam shim w/ pimoroni software installed. Soldered pins to the modem holes labeled Nextion, wired accordingly. In Pi-Star, set the display type to Nextion, Port to Modem and chose the Layout of ON7LDS HS. The display powers-up, but no data is displayed.

To eliminate the possibility of a bad display, I have succeeded in connecting the display via FT232RL / USB. Works great.

Some other troubleshooting steps included: 1) power cycling. 2) switching between Wait on LAN 1 to 0, then back. 3) switching the layout to the low-speed option.

I'm fresh out of ideas and really need some help, please.

Nevermind, all. I've decided to solder a FT232RL to the Pi and move on.

Modem connected displays will not work in HS layout. The communication speed modem<-->display is programmed in the modem and is, as far as I know, always 9600baud. In any case, you have more flexibility with an USB-RS232 solution. Not only to use the higher communication speed but then you can also use buttons on the Nextion to start some actions on the Pi.
