Hello,
I'm trying to develop a circuit to read the speed/rpm/acceleration using a GPS module a tachometer and an accelerometer. I've assembled the circuit and everything works as expected except for the LCD. An old 16x2 hd44780 based LCD is not fast enough to show all the details in realtime (like a bar graph when I rev up the engine) so I've been researching to see if I could find a replacement but couldn't find anything.
Does anyone know any screen that don't suffer from extreme lag? I've seen some 126x64 cheack screens on ebay but they all seem to slow (at least on youtube).
Thanks!
