retrofit a bigger screen
Connections with LCD incompatible, firmware has insufficient free space
See wiki /files for a possible retrofit -- NanoVNA Wiki: /g/nanovna-users/wiki/home NanoVNA Files: /g/nanovna-users/files Erik, PD0EK |
Another way to do this would be to package it up with an Android tablet and use NanoVNA WebApp as the user interface (remove or hide the built-in LCD).
I'd like to try this but the android app won't load on my older tablet, despite it having been updated to Android 6.1. It would also be possible to build in a raspberry pi and use nanovna-saver, but the android app seems a better fit if you don't have a keyboard. |

Actually, his Android app still calls home to mama Google for statistics.??
If you have your Android device's WiFi enabled and connected, the NanoVNA app starts right up. However, I run a firewall (No-root firewall by Greyshirts) on my Android devices and the network request from the NanoVNA app (when it starts up only) takes about 60 seconds to timeout before the main screen appears. If I allow the app through the firewall, it starts immediately. I spoke to CHO45 about this and he said it's the Google library he's using as he explicitly performs no network requests.

Calm down Paul! No one can tell you which one is better because it's personal preference. Besides, there is only one person who attempted to change the display and that info is in the Wiki/Files section of the forum (Herman's work). Now's the time to experiment - look at the specs and buy the display that matches the interface - simple. Search the 7500+ messages - hopefully, you'll find more info. |
Do the LCD modules you selected have 18 pin connectors as described in the wiki?

Unless I misread the diagram those displays have 40 pins. Good luck on your search. Did you check that they use the same controller? On Thu, Nov 28, 2019 at 1:38 PM <erik@...> wrote:Do the LCD modules you selected have 18 pin connectors as described in the |
