Probably this is specific to my displays, which are not from Adafruit although they look identical (exept they are just TFT-s without PCB and SD) and based on the same controller IC as ones from Adafruit. </p> http://forums.leaflabs.com/topic.php?id=897&page=3#post-7217 Tue, 22 Nov 2011 11:23:23 +0000 siy 7217@http://forums.leaflabs.com/ <p>Peter, my message should be in your mailbox already (unless hotmal decided that it is a spam :). </p> http://forums.leaflabs.com/topic.php?id=897&page=3#post-7214 Tue, 22 Nov 2011 09:45:18 +0000 pra 7214@http://forums.leaflabs.com/ <p>send an email to <a href="mailto:peterrarcher@hotmail.com">peterrarcher@hotmail.com</a> and I'll email what I have to you </p> http://forums.leaflabs.com/topic.php?id=897&page=3#post-7213 Tue, 22 Nov 2011 02:57:22 +0000 siy 7213@http://forums.leaflabs.com/ <p>Can someone point me where I can get sources for the ST7735 library (I mean version for Maple, of course)? </p> http://forums.leaflabs.com/topic.php?id=897&page=3#post-5805 Fri, 29 Jul 2011 18:28:29 +0000 pra 5805@http://forums.leaflabs.com/ <p>I'd be interested. For font and other LCD stuff, you might want to look at LCDAssistant and LCD Font Maker. I have them both, and they are shareware appls for WIndows. </p> http://forums.leaflabs.com/topic.php?id=897&page=2#post-5785 Thu, 28 Jul 2011 20:43:31 +0000 Zouk 5785@http://forums.leaflabs.com/ <p>Still away from my main computer, but I did sit down on my laptop and write a little tool in C# to determine 12-bit colors. Just 3 0-255 sliders for RGB, a color swatch, and text boxes to copy the color in 24 / 18 / 16 / 12 bit color. Dunno if anyone else needs something like that; if anyone needs it, I can upload the program and the project files. Not sure if something like that already existed, but I was bored, needed it, and couldn't find it on the web.</p> <p>Gonna build a little font creator next, if anyone needs something like that? </p> http://forums.leaflabs.com/topic.php?id=897&page=2#post-5742 Mon, 25 Jul 2011 16:24:49 +0000 pra 5742@http://forums.leaflabs.com/ <p>I'm sure the SDFat library supports creating/writing files as well as reading them. I also had the problem with my other LCD endeavor where the touchscreen only supports a slow SPI speed and the larger LCD pretty much made 9MHZ mandatory. I put in new SPI.begins in every touchscreen read function, restoring it back to the LCD speed before exiting the function. You can probably do similar with the SD </p> http://forums.leaflabs.com/topic.php?id=897&page=2#post-5740 Mon, 25 Jul 2011 11:30:48 +0000 Zouk 5740@http://forums.leaflabs.com/ <p>Ah damn, I might do switching between them or something. I've not looked at the SD card code yet; if the sketch supports writing to it, that would be a really fantastic alternative to adding an EEPROM chip to my project. </p> http://forums.leaflabs.com/topic.php?id=897&page=2#post-5738 Mon, 25 Jul 2011 11:05:08 +0000 pra 5738@http://forums.leaflabs.com/ <p>Great work!! - I'll be interested in getting the code when you get the chance. I knew the display worked fine at 9MHZ, the SD card doesn't however. It can only handle 4.5MHZ. </p> http://forums.leaflabs.com/topic.php?id=897&page=2#post-5737 Mon, 25 Jul 2011 09:38:59 +0000 Zouk 5737@http://forums.leaflabs.com/ <p>Wow! I got in the rhythm of working on the project that involves this display and completely forgot about this thread. I did get it running pretty well in landscape mode without much difficulty. I'll post code when I have access to my primary computer again. Until then, I'll explain what I did.</p> <p>I modified the lowest level stuff possible - drawFastLine(), drawPixel(), fillRect(), and maybe drawChar(). I'll have to go back through and look. Prettymuch anything that calls setAddrWindow() and starts writing via SPI needs modification.</p> <p>All I did was change up the logic so that the lower left and upper right corner of any "landscape mode" operations you do would be the ones fed to the setAddrWindow() function, rather than the upper right and lower left as would be in portrait mode. Also, any height/width checks need reversal.</p> <p>Two additional things of note. One, the display seems to work fine at SPI 9MHz. Two, fillRect() is bugged. Any rect you draw will be one pixel too long on one end, so it will render improperly. So a 10x10 square will actually be 11px long in one dimension, so you'll get an 11x9 rectangle with a little pixel tumor where the 100th pixel went. Discovered this and fixed it when I was duct taping the library. </p>
