I really have no more idea how to fix it and tryed it more than 2 hours □ of the Arduino Software and downloaded all the 3 library packages, but there are these errors: I’ve also bougth an Arduino DUE and a 3.2″ TFT LCD from elechouse but I can’t download the examples to the Board. Nice Page and Idea for helping others! □ Here is a little video I made of the 3.2″ TFT running a UTFT demo sketch: In case of the Due the resistors are not necessary since it uses 3.3V logic so it is directly compatible. That will bring the voltage down to acceptable levels. You need to connect a 10K resistor in series with each and every one of the lines. This means that if you connect the D0-D15 and RS, WR, CS, REST lines directly to the MEGA you will most likely damage the TFT. The Arduino MEGA is using 5V logic while the TFT is expecting 3.3V logic. Now, there is one more thing that I should point out and it is very important. Note that I have not really gotten around to using the touchscreen capabilities or the SD reader, so I have not connected them to my Arduinos. This leaves pin 1 which must be connected to ground and pin 3 which must be connected to Vcc which in our case is 5V. Pin 37 is the backlight illumination which means it must also be connected to +3.3V. Pin 11 is RD and it must be pulled high, which means connecting it to +3.3V. Then we also have to connect pins RS, WR, CS and REST to whichever pins we like (we must declare these pins in our sketch, see UTFT documentation). So we have to connect signals D0 through to D15 to the necessary digital pins. Note that the connections are made according to UTFT’s documentation and are applicable specifically to UTFT. Above and below the signal lines I have noted the actual Arduino pins that correspond to the signals.įor example, pin 2 (the second pin on the flex cable looking at it from the left) corresponds to the DB0 signal which should be connected to the D37 pin on the Arduino MEGA (or Due). What we have here is the actual conductor number in the grey background (counting the conductors in the ribbon cable from left to right) and then above and below them the corresponding signal lines according to the above pinout. At first I thought I’d try to make sense of it as I went but it didn’t take long for me to realize that it would actually save me time if I made a “conversion table”. This is nice, but I want to use a standard 40-pin ribbon cable which I have left over from an old computer, and its conductor numbering is a little different. This is its pinout according to the manufacturer: The below instructions apply to a generic 3.2″ TFT with wide aspect ratio and resolution of 240 x 400 that I got off of Ebay. The answer of course depends on the exact model of the TFT that we have on hand. I’ve been asked what is the correct way to wire a 3.2″ TFT to an Arduino MEGA (or Due) in order to make it work with the UTFT library. Still, keep in mind that the info posted below still applies and is probably useful.
