Tips and Tricks

Diag Information

Someone brought up this tip:

1) eject the SD card (remove it completely)

2) push the TTGO on and keep it pushed

you now will see some data, like calibration data. serial number, bootcode, battery voltage. (I'll include the original source of this info if I can find it)

Startup/shutdown picture

Another thing that's fun is to have a picture displayed when starting the TTGO or stopping the TTGO.

For version v4.xx

Create a BMP of 240x320, 256 colours (8 bit) and place it into the root of the filesystem. You'll have to call it spsystem (without the .BMP extension). Smaller pictures also work.

For version v5.xx

For version v5.xx the file is 320X240 (32 bit) and called splash.bmp and also goes into root.

For version v6.xx

On GO 510 there are two files, named splashw.bmp and suspendw.bmp. They are standard 24 bitmaps, 480x272. I assume "w" in splashw and suspendw' stands for widescreen. The dimensions might vary on other models. Just drop your own bitmaps in the root directory overwriting the existing ones.

For the Tomtom One the files are called "splash.bmp" and "suspend.bmp" and have a resolution of 320x240.

For version v7.xx

For the Tomtom One the files are called "splash.bmp" and "suspend.bmp" and have a resolution of 320x240, 24 bit depth.

Here is an example:

Other customizations

You can customize your TTGO, without compilation or other, just create file(s) and directories.

See menu structure.

See new color map.

See handfree TTGO 500 and 700.

enjoy.
