I was looking around for 16x2 or preferably 20x4 lcds to plug into my Teensy 3.0. While there are a lot of these boards out there, most seem to be 5v. So, I was wondering am I missing suitable displays or are people with Teensy's just using voltage converters to talk to 5v devices? What are people using with their Teensy's. I would prefer something that uses either serial, i2c, or spi (in that order), but if the only solution is something that uses 7-10 pins, I can probably deal with. I am not really looking for high performance, mostly something that works with minimal effort. At the moment, my remote display is using my phone with bluetooth.
So far, I found one 16x2 display at Adafruit (does not work with i2c/spi backpacks, uses 7 pins): http://www.adafruit.com/products/823. Adafruit does have a simple library for this, and it doesn't look like it uses asm.
I also found an ebay seller with an i2c display using the ST7032i chipset: http://www.ebay.com/itm/290947405866?ssPageName=STRK:MESINDXX:IT&_trksid=p3984.m1436.l2649. I've seen some references to software on the web. Hopefully openGLCD will support it.
There are some 3.3v graphic displays using the SPLC780D chipset, such as: http://www.ebay.com/itm/1602-16-x-2...040?pt=LH_DefaultDomain_0&hash=item27d1641290.
There are also some SPI displays that don't feel it is important to mention the chipset, such as: http://www.ebay.com/itm/1PC-2-2-Inc...712?pt=LH_DefaultDomain_0&hash=item1c357f4dc0.
