The TFT actually works right now here (using their example code, but i'll talk to you personally about that and what that means [since i almost have it working using mine]). What i need more than anything right now is real documentation on the screen itself. After it's setup with the FSMC, what the heck are each of those commands i'm sending to it? Unfortunately, the docs on the TFT (a totally different TFT) are in chinese. </p> http://forums.leaflabs.com/topic.php?id=1236&page=2#post-10074 Mon, 02 Apr 2012 23:57:31 +0000 kb113400 10074@http://forums.leaflabs.com/ <p>St has an application note related to the ili9320: <a href="http://www.st.com/internet/com/TECHNICAL_RESOURCES/TECHNICAL_LITERATURE/APPLICATION_NOTE/CD00201397.pdf" rel="nofollow">http://www.st.com/internet/com/TECHNICAL_RESOURCES/TECHNICAL_LITERATURE/APPLICATION_NOTE/CD00201397.pdf</a></p> <p>on page 15 is a specific reference to a tft display, 320x240, driven by an ili9320. page 15 or in the index :Interfacing the Ampire AM-240320L8TNQW00H TFT LCD with the FSMC.</p> <p>It makes for interesting reading.

In reality all the hardware is controlled by memory mapped registers, so understanding pointers allows you do what you want once you know the memory locations. </p> http://forums.leaflabs.com/topic.php?id=1236&page=2#post-10030 Fri, 30 Mar 2012 02:13:01 +0000 kb113400 10030@http://forums.leaflabs.com/ <p>If you have any useful links I would really appreciate it. </p> http://forums.leaflabs.com/topic.php?id=1236&page=2#post-10029 Fri, 30 Mar 2012 01:51:22 +0000 kb113400 10029@http://forums.leaflabs.com/ <p>Yeah, I've just realized how over my head most of this is.

I'll see what i can do when i get there, but for the most part i might just recommend you use C++ to begin with and ditch their IDE (no offence, leaflabs), as i've had nothing but trouble with it. Maybe you'll give me that excuse to write a short textbook on the basics of C++ necessary to do 90% of the coding you'll ever do. </p> http://forums.leaflabs.com/topic.php?id=1236&page=2#post-9808 Sat, 17 Mar 2012 22:31:29 +0000 kb113400 9808@http://forums.leaflabs.com/ <p>Yeah, assembly might be a bit beyond my scope, I'm kind of a noob when it comes to coding. I worked with a trs-80 and the H.e.r.o. 1 kit when I was in high school, but that was mostly hex code, and I had teachers helping me. I've re-purposed the odd disposable piece of tech (built a mame cabinet and wired up a couple of buttons to an old usb controller breadboard). As of right now my main goal for this project is to have a interactive monitoring panel for a few analog sensors. I have 3 capacitive liquid level sensors, one voltmeter, one ammeter, and a temperature probe. I,need to write a menu and a few simple graphic readouts, as well as a way to use the micro sd to log data.<br /> I'm replacing the sensor board in my motorhome, and I wanted it to be smarter than the average box on wheels. The average rv monitoring panel is a simple led readout and it costs $200. I can do better. I figure I need a voltage divider to bring the input down to acceptable levels (most of the existing sensors run at 5v, the voltmeter has a 20v range, the ammeter is a shunt over the positive line).</p> <p> Most of my experience tends to be from the analog side of life, so the smart circuitry is somewhat challenging for me right now. I'm slowly getting a grasp on the language, but I'm no codemonkey. </p> <p>Yeah, I kind of got the brushoff until I started mentioning returning or exchanging the board, then they got helpful. I'll admit I'm probably over my head here, but I want to learn embedded tech, and I'm willing to sacrifice $70 to do that.</p> <p>A bit disorganized, me. I'm working on it. </p> http://forums.leaflabs.com/topic.php?id=1236&page=2#post-9003 Sat, 17 Mar 2012 00:51:18 +0000 kohlrak 9003@http://forums.leaflabs.com/ <p>There's some projects that come with their own bootloaders and stuff that you can use, too. since i'm not afraid of assembly, i'll be taking advantage of this. It wouldn't be too hard, though, to take the assembly and learn from it. Right now, their technician is looking into why the vga example isn't compiling (the touchscreen example is compiling, though). I'm surprised they're actually working with me on this (very slowly hoping i go away though). </p> http://forums.leaflabs.com/topic.php?id=1236&page=2#post-8807 Fri, 16 Mar 2012 21:27:11 +0000 kb113400 8807@http://forums.leaflabs.com/ <p>add banana no.3 I was a fool and saw all the specs+a shiny tft touch display and bought it. After dealing with the "wonderful" people at linksprite/soliddigi/cutedigi, for a week or so, I finally bought an rs232 to usb cable and flashed on a bootloader Let me know what the latest is on the touchscreen please. I would very much like to get that running on maple. </p>
