[TriEmbed] TFT'S from Hamfest

[John Wettroth]

I’m using code from Seeed Studio- who I guess made these things.  Its called TFT Touch v4.2.  All installed find and I ran the examples out of the box with no trouble.  Plopped the shield on an Uno, no drama at all.  I’ve some other ideas where color graphics could make a difference.   I was really impressed by the color depth (64K).
 
The display module itself runs on 2.8v- there’s a regulator from the 5v from the Aduino.  The uSD Card runs on 3.3v with another linear regulator.  There are real level shifters on all the lines and a good set of jumpers and links to customize things.  The resistive touch panel goes directly into the Arduino’s ADC’s- no extra chip.  Works pretty well and a good example in the library.  The backlight Is a bit of a hog- may adjust resistor value.  Its default jumper is to be on all the time- but there is a jumper for control.  Schematics are on the SEEED site- current product that sells for about $20 IIRC.  I couldn’t get the example SD card to load but I didn’t spend any time on it- its pretty simple, just SPI and a CS, might have a bad card?

Take care.

I also bought some of the displays, but have not even  unpacked them out of the car yet... but I was wondering what code you were using with the displays and where to get it
