480x320 tft lcd fritzing for sale

Here we are going to look at creating parts with schematic subparts. The purpose of schematic subparts are to allow elements of a multi element part (such as a dual op amp or a hex inverter) to move around schematic independently. I will use the 74x125 quad tristate buffer as an example of this. We will look only at the schematic svg and the fzp file as they are the only two files that are affected by this. Note that schematic subparts block the use of buses in the same part, I don’t know why and fixing that is a desirable enhancement but at the moment, subparts block the use of buses. First the 74x125.fzpz file so you can load it in to Fritzing and see what it does, and unzip it to get the fzp and schematic svg files that make up the part:

The layout is similar to buses. Each subpart has a label (which needs to match the group id in the svg file) and a list of the connectors that make up the subpart. The connectors can only be in one subpart and as noted the part can not (at present at least) have buses defined. One drawback of subparts is a lot of them (around 10 to 12) in a sketch will start to slow rendering down. Presumably the more subparts present the slower rendering will become. However for some parts (such as logic buffers in this case and dual or quad op amp parts) they are very useful and not that difficult to create once you know how. The FritzingCheckPart.py script understands and will catch configuration errors (in the fzp file only, not the svg so much) to help keep things straight.

This is a little display for the Raspberry Pi, It features a 3.5" display with 480x320 16-bit color pixels. This version has a capacitive touchscreen, you can now use your fingers.

Use it for console access or easily pop up X11 onto the PiTFT for a mini monitor, although its rather small at 320x240. Instead, we recommend using PyGame or other SDL-drawing programs to write onto the frame buffer.

If you’re still planning on “going it alone” then I suggest having a proper thorough look through the “lcdwiki” to see if the board you’re looking at is there – http://www.lcdwiki.com/Main_Page.  This might make things a lot easier!

MCUFriend TFT library for range of MCUFriend displays which includes support for some ILI9488 based modules: https://github.com/prenticedavid/MCUFRIEND_kbv/blob/master/MCUFRIEND_kbv.cpp

The “TL;DR” version is that to use the display with the widest range of microcontrollers, I’d recommend taking a look at the Arduino_GFX library by “Moon on our Nation” and read the LCD Wiki for more specific details.

I’ve used two devices as there are five signals that need level shifting: MOSI, CLK, CS, DC, RESET.  MISO does not need to be level shifted as this is the “LCD to microcontroller” line, so that is being driven at 3.3V but going into a 5V microcontroller line which is fine.

“the typical Adafruit TFT libraries are designed to work with 16bit color (RGB565), and the ILI9488 can only do 24bit (RGB888) color in 4 wire SPI mode.”

I’ve included the connections for the touchscreen, which largely consist of adding it to the SPI bus and adding two IO pins for the Select and IRQ lines.  I’ve used slightly different IO pins for some of the TFT connections too to make the wiring slightly simpler. The updated wiring for the display is as follows:

Here are some photos of the build process for reference.  I’ve tried to stick to the same colours as the Fritzing diagram (although my “ochre” looks very like my “orange” in places!).

The blue wires complete the links between the level shifters and the TFT header.  Once again, you can see the extra wire to T_IRQ which I remove later! I opted to take one of these underneath, the CLK signal seemed to make more sense that what as shown below.

Now I have a reliable way to actually talk to the display module, I can get on with trying to drive the touchscreen.  If you want to follow along with a solderless breadboard (not recommended – it caused me no end of grief as there are just so many connections) here is an updated Fritzing diagram.

Add some jazz & pizazz to your project with a color touchscreen LCD. This TFT display is big (3.5" diagonal) bright (6 white-LED backlight) and colorful! 480x320 pixels with individual RGB pixel control, this has way more resolution than a black and white 128x64 display, and double our 2.8" TFT. As a bonus, this display has a resistive touchscreen attached to it already, so you can detect finger presses anywhere on the screen.
