Hey Everyone,


Been searching the forums and found a lot of different resources/links to different drivers.. I'm looking for a simple to implement and preferably easy hookup to SPI/I2C bus. 


I'm looking for a LCD like a 16x2 display that I can update/refresh somewhat quickly/smoothly

Can anyone make an suggestions/links of hardware to purchase/drivers to use. I'm open to use I2C or SPI

I was looking at this one as it's cheap: - will this work with available drivers?

Or the adafruit 16x2 with I2C Backpack?


i like this product: needs the backpack

OR are there any other LCDs/Screens are similar to a 16x2 that are easy to interface? Possibly an OLED display at 3v?

I've recently been playing with the DOG series of LCDs from EA.




Fairly inexpensive. Works well with 3.3v and SPI support on Netduino 1 and Netduino Mini. Requires a couples of series resistors for the backlight, and two capacitors if using 3.3v. Uses a fairly standard HD44780 command set, although font selection is different.

Those looks like nice LCDs. I'll look around in the US for those.



In the meantime, I'm going to try this out: i2c

Anyone know any good working drivers for this display based on the PCF8574t?
