Tuve que cambiar la primera que compré porque empezó a oiscilar la iluminación de la pantalla.
Por lo demás todo muy bien, buena presentación y buen funcionamiento.
The display is clear and the characters are legible. I do wish this display supported more than 32 characters. As for interfacing, that is very easy. Just a hand-full of switches (and one potentiometer) and an ASCII chart you don’t even need a microcontroller (but you’ll only be able to print one character every few seconds without one).
Display is Much brighter than the picture, and even though it was a bit scary to solder onto (im a bit of a newb at soldering) , it works fantastic! So bright, Very responsive. I dont even have the display at its brightest and it is a crystal clear read! Look forward to using it in my summer project.
The LCD arrived promptly in the mail and worked as advertised. If my experience is typical of Sparkfun, they have good products and are very efficient.
I wired up the display and ran it with the standard Arduino library. Worked first time!
Apparent color changes from white-on-black to black-on-white at ~ + 5’ and ~ -20’. Readable until ~ + 35’ and ~ - 80’. During the color change, it’s difficult to read; a lot of head bobbing is required. Readability at greater + angles would be better for my application. Is there any way to flip the text orientation or, perhaps, another hack to improve upon this issue? I won’t be purchasing this product again.
