[P116] ST7735/ST7789/ST7796 TFT Plugin and AdafruitGFX helper #3761

tonhuisman · 2021-08-13T19:28:02Z

New plugin P116: ST77xx TFT
- Supports ST7735s/r 128x128, 128x160, 80x160 pixel TFT 65535 color displays
- Supports ST7789vw 240x320, 240x240, 240x280, 135x240 pixel TFT 65535 color displays
- Supports ST7796s 320x480 pixel 65535 color displays
Introducing AdafruitGFX_helper class, as a generic interface for all displays using the Adafruit_GFX library
Add some optional fonts (1 proportional, 5 fixed width), disabled by default
Plugin is included in DISPLAY builds, that have been set to LIMIT_BUILD_SIZE for ESP8266 to acquire some .bin space

Just a tip on libraries...
If you have a PlatformIO account, you can also publish a library version of your own.
Then prefix that library, just with your own account, like Adafruit does. (and I have for a few libraries, using td-er/ )
Only bad thing about it, is that you need to re-publish (and update version) every change you make.
Made that mistake a few times with the ESPEasySerial library that I forgot to publish it again.

tonhuisman · 2021-08-14T08:30:46Z

Thanks for the pointers.
I'm currently always compiling the new helper class, that pulls in the Adafruit GFX library, but that isn't working for the IR builds, f.e., so I'll have to enable it separately.

TD-er · 2021-08-14T08:47:32Z

Well if you're done with the lib changes to make it work with ESPEasy, we can make it into a separate library for our own.
You can also rename it in the library properties in the lib/ dir and mention that in the required libs (not sure if it is needed then...)
We may need to re-think this how to manage it as it is quite often an issue when patching libraries for our own use.

tonhuisman · 2021-08-14T09:18:27Z

The only 'requirement' for this lib is that it doesn't pull in the SD library, as that collides with the ESPEasy SD support. (Some of these TFT displays come with a SD card-slot, that's used to display graphics in some of the examples, and that seems the reason they pull that one in, AFAICS, but I don't want/need to include these examples...)

Command unknown

tonhuisman · 2022-05-08T13:58:49Z

I'll have a look

tonhuisman · 2022-05-08T14:05:59Z

What output do you get in the log (serial or weblog) when issuing this command? Mine shows:

HTTP: st77xx,bmp,0,0,adabot.bmp
Error  : showBmp: file not found

But that's to be expected, as my unit doesn't have that file uploaded 😉
The response in the UI then also is Command unknown
NB: I've installed the .bin file that I just uploaded.

tonhuisman · 2022-05-08T14:10:42Z

And when using a filename that is on the filesystem I get this:

Info   : HTTP: st77xx,bmp,0,0,droid80.bmp
Info   : showBmp: bitmap w:80, h:80, dpt:24, colors:16777216, cmp:0, pl:1, x:0, y:0

If you connect BLK to VCC, I expect the display to work. An issue regarding PWM on ESP32 has been fixed after the 20220427 release.
If you download and install the Display bin from f.e. this Github Actions build, the backlight control should work again as intended.

Can you try the Display build from this Actions run ?, that adds some more supported display models to the ILI9341 plugin (P095).
The ST77xx driver (P116) is not going to work correctly with an ILI934x display, that's for sure.

If you also include a background color in your txtfull subcommand: ili9341,txtfull,0,60,3,white,black,%systime%-%uptime%, then it won't have a transparent bg-color that doesn't erase what's already there, but overwrite any previous text with black 😃

How do I enable other fonts in a custom build?
ps：enable whitrabt8pt

tonhuisman · 2022-05-14T13:44:23Z

How do I enable other fonts in a custom build? ps：enable whitrabt8pt

2 ways:

If you have copied Custom-sample.h to Custom.h and enabled the desired plugins, then add a line:
# define ADAGFX_FONTS_EXTRA_8PT_INCLUDED
If you are just local-building with an existing Display build, then in file AdafruitGFX_helper.h around line 48 enable the define mentioned above, and also disable around line 81 # undef ADAGFX_FONTS_INCLUDED, as it may be in the LIMIT_BUILD_SIZE sets (though in up to date sources from mega branch this is no longer the case for ESP32)

Can I add fonts that are not in the library separately?

for example：Roboto Font Family

tonhuisman · 2022-05-15T13:54:20Z

Fonts have to be converted to data, and compiled into the bin before they can be used.
I've added 3 fonts, Roboto, RobotoCondensed (both proportional width) and RobotoMono (fixed width) in 3 sizes, 8pt, 12pt and 16pt to a custom build for testing.
This build is based on the current mega branch, and has all fonts explicitly enabled. For regular MAX builds, that already have had all fonts included until now, I'll only enable the RobotoMono fonts (they seem the most usable), and leave the others as optional for a local custom build. This will be in a new PR soon.

Ah after deleting my downloaded files, I got a similar error.
Can you change in platformio_core_defs.ini this section:

[core_esp32_IDF4_4__2_0_3]
platform                    = https://github.com/tasmota/platform-espressif32/releases/download/v.2.0.3/platform-espressif32-v.2.0.3.zip

Leave the rest as is.

If that still results in errors, please delete te following (selected) folders in your user home dir in .platformio:

Then you may need to call a "clean All" build (which results in an error) and then again make a new build.

Does that work better if you do not use the roboto8pt font?, or use robotomono8pt?

zhangqilaw · 2022-05-18T13:29:07Z

Does that work better if you do not use the roboto8pt font?, or use robotomono8pt?

If you use the default font, the display is normal, with roboto8pt or robotomono, the numbers will be displayed by the robot.

Hm, it gets quite confusing if you show alternating the ILI9xxx and the ST77xx displays. The net result will be the same on both (they use the same code for displaying), so please keep it to 1 display/rules version you share.

Possible cause is that the space character for this font isn't wide enough (or 0) to wipe out the previous content. I'll have a look.

I tested ili9341 and st37xx, both of which have the same problem. Maybe font isn't wide enough (or 0)，Which piece of code should be modified?

TD-er · 2022-05-18T14:43:45Z

The colon on the last picture also doesn't look like it is monospaced.
So perhaps the font doesn't have proper widths reported in the font?

The true in that calculateTextMetrics() call indicates it is a proportionally spaced font.

I'm working on fixes in this area, just haven't ironed out all the wrinkles yet.
