Highly optimized ILI9341 (320x240 TFT color display) library

[Frank B]

You have 256KB available, you're using less than 1/4.

You have 256KB available, you're using less than 1/4.

But that is only for the fonts. Adding all the other stuff, including FFT etc I am at 208 K already and there is still something to add. Since I have added the fonts compiling has become hit and miss, often giving me a "exit status 1 Error compiling" error. Knocking off the letters may solve that problem because I would likely gain back in excess of 25 K.

Wow, this is a very long thread and I confess not having read it in its entirety. The fonts are great and work well with both the 2.2 and 2.8 inch displays from PJRC. They do take a lot of memory though, especially when the larger ones are being used.

In my case I am using only font_LiberationSansNarrowBold and have restricted it to 4 sizes. Still the combined memory hit was about 50 K for the sizes 12, 16, 48 and 96. I am using the small ones to display some descriptions and explanations, i.e. letters are used but the big ones only display numbers - measurements and parameters. This may be the case for many applications not just mine.

Large memory saving could be achieved, if numerics (in my case just numbers and a decimal) would be available as a separate library, which could be called font_LiberationSansNarrowBoldNumbers as an example.

I had this problem myself and modified the font converter in extras to take an option to generate a Fontname_Digits.c/.h file that only had the digits and some punctuation.

I pushed my changes to my branch here: https://github.com/blackketter/ILI9341_t3

For example running:

./ttf_to_ili9341.pl -digits Arial

Generates a font file roughly one quarter the size of the full font. Let me know if this helps!

Thanks for your note, it is what I was referring to. That is even more memory savings than I expected. However I am using the Liberation Narrow Bold font, it fits just the right amount of digits at 96 point size. I have not tried a conversion on my Mac, but having just digits would be a good feature overall.

Try these and see if they work for you...

Hi Blackletter, apart from a message (below) during compile, which I am ignoring at this time, it worked. It saved about to 30 K in my case using 48 and 96 points. Now that it is back down to 173 K program storage the "exit status 1 Error compiling" error has disappeared as well.

Thanks.

Glad it's working! I'm not seeing those warnings. What build environment are you using?

I added Zach Archer's amazing DemoSauce animation to the ILI9341_t3 library.

This demo lacks some c64-sid-style sound...definitely
We have plenty of flash left.. hm..
I think i know what i do as soon i have some time tomorrow or @weekend...

 

[Frank B]

Edit:
Ha! That was far more easy than thought
I'll upload a video and the source tomorrow.. (too late now, midnight...)

 

[Frank B]

Here's the video.
Sound is from headphones, recorded with my cellphone so, the qualtiy is not good..

I can upload the sourcecode if anyone wants it...
The music is from the file "pp_hammer.dmp" (for the reSID SID Emulation).
Additional audio-obbject is "AudioAnalyzeRMS"

I am trying to use your ILI9341_t3 library with Arduino ver 1.6.6 and trying verify and compile the Graphictest.ino using Mega 2560 and the
following errors are generated:

I am using 2.8 Adafruit TFT and need to adjust the font size for a project, their library only has 1, 2 3 , 5 for font sizes. thanks in advance for any help.

Arduino: 1.6.6 (Windows 7), Board: "Arduino/Genuino Mega or Mega 2560, ATmega2560 (Mega 2560)"

For Arduino Mega, you have to use Adafruit's (slow) library.

The optimized ILI9341_t3 lib only works on Teensy 3.x. It doesn't even work on Teensy LC or 2.0. The optimizations use the FIFO and chip select hardware on Teensy 3.0, 3.1, 3.2. No other boards are supported.

Thanks for the quick reply, is there any other library that supports different fonts for this controller?

Thanks for the quick reply, is there any other library that supports different fonts for this controller?

I believe that within the last month that Adafruit added support for extra fonts in their standard GFX library so wouldn't that work?

Also I've used https://github.com/pkourany/Adafruit_mfGFX_Library but that is probably obsolete now that the official library supports additional fonts.

I hope that helps,

DemoSauce with SID-sound:

I can upload the sourcecode if anyone wants it...

done:
https://github.com/FrankBoesing/ILI9341_DEMOS
(see "examples"-folder, you need to install my reSID library and adjust your hardwarsettings)

Works best with 144MHz, -O2

Just wondering if anyone has ported this library to the raspberry pi ?

Hi Paul,
hopefully the code below will help.

The bug shows whether or not I add 2.2K pull up resistors to the CS lines of the TFT display and of the EEPROM in your audio shield.

The first incarnation of the bug shows up performing a simple flash_read_id(id_tab), i think this is really all you need.
You would need to pre-load the first few bytes of the EEPROM if you want to see the second manifestation of the bug - which I think is the same bug, still related to a read function.
I did not test writing to EEPROM while using ILI9341

While I am able to get going with the project, I already miss the speed of ILI9341_t3 ....

Thank you
alfa66

Hi Paul,
Since I was not able to get this to work, I reverted back to the Adafruit library, but i really need more speed for my project.
I noticed that, in the meantime, you released a new purple board for the display.
I was familiar with the power fix, but can you please tell me what has changed with the reset? I wonder if the issue above is related to the interaction with the purple board.
Thank you in advance,

 

[PaulStoffregen]

Looks like you're using this:

// Needed when using ILI9341 with the Audio Board, also needed for reading W25Q128
SPI.setMOSI(7);
SPI.setSCK(14);

But you have only this for the display:

ILI9341_t3 tft = ILI9341_t3(TFT_CS, TFT_DC);

You need to use this:

#define TFT_DC      20
#define TFT_CS      21
#define TFT_RST    255  // 255 = unused, connect to 3.3V
#define TFT_MOSI     7
#define TFT_SCLK    14
#define TFT_MISO    12
ILI9341_t3 tft = ILI9341_t3(TFT_CS, TFT_DC, TFT_RST, TFT_MOSI, TFT_SCLK, TFT_MISO);

For more info, read the ILI9341 page:

http://www.pjrc.com/store/display_ili9341.html

Scroll down to the "Usage With Audio Board Connections" section.

 

[PaulStoffregen]

Also, for a known-good program which uses the display and a SD card, look in File > Examples > Audio > Tutorial > Part_3_03_TFT_Display.

This example requires using the design tool. For details, see the workshop PDF:

https://github.com/PaulStoffregen/AudioWorkshop2015/raw/master/workshop.pdf

If you watch the tutorial video, you can see if running in the last few minutes.

 

[alfa66]

Thank you Paul!
I will give it another try.

Also, I will look at the code example for the display + SD card.

I saw the tutorial, well done - it helped me moving forward with my project.

Thanks again!

Hey Guys,

I was just wondering if there is a way to either force the new fonts to display as fixed width or when they are generated, adjust the parameters so they are a fixed width font?
The new fonts work really well just the fixed width is kind of tripping me up.

Cheers

Did you try using the Courier font? It should be fixed width.

Hey, I submitted a pull request with some library updates.

I added:
Gradient support
fillRectVGradient - fills area with vertical gradient
fillRectHGradient - fills area with horizontal gradient
fillScreenVGradient - fills screen with vertical gradient
fillScreenHGradient - fills screen with horizontal gradient

Additional Color Support
color565toRGB - converts 565 format 16 bit color to RGB
color565toRGB14 - converts 16 bit 565 format color to 14 bit RGB (2 bits clear for math and sign)
RGB14tocolor565 - converts 14 bit RGB back to 16 bit 565 format color

Low Memory Bitmap Support
writeRect8BPP - write 8 bit per pixel paletted bitmap
writeRect4BPP - write 4 bit per pixel paletted bitmap
writeRect2BPP - write 2 bit per pixel paletted bitmap
writeRect1BPP - write 1 bit per pixel paletted bitmap

String Pixel Length support
strPixelLen - gets pixel length of given ASCII string

and I fixed the text routines so that linefeed would actually work.

I ended up submitting it in two separate patches because I couldn't determine how to merge the changes (I am a Git newbie.)
https://github.com/PaulStoffregen/ILI9341_t3/pull/24
https://github.com/PaulStoffregen/ILI9341_t3/pull/25

Please give it a shot and let me know if there are any problems.

Any way to make this library work with the Teensy LC? Or does that have too little memory to make the attempt. The code currently uses KINETISK_SPI0, which is not defined on the Teensy LC (being a KINETISL processor). Or should KINETISK_SPI0.SR be replaced with SPSR in the code (in readcommand8, for example)? What about KINETISK_SPI0.PUSHR and KINETISK_SPI0.POPR?

How much rewriting is needed to get the display to work on the Teensy LC?
