Hi,
I want a large 20x4 LCD display for projects where at a distance(1,2m) it should be readable.
This time I went for another(white 20pins) large 20x4 display then my previous(blue 16pins) medium 20x4 display mentioned in one of my threads.
I've been testing how to drive it also with @marks PICAXE 20X2 driver code without succes.
a) What am I doing wrong:
* I've connected pins1-6 to (Vss,Vdd,Vo,RS,RW,E), and pins11-16 to (DB4-7) of the 20X2 driver,
* Also (LED+ 5V)pin20 to LED_A of the 20X2 driver.
* This white display has 4 extra pins "active" Low:
* The Reset (pin 16) I tied to +5V to prevent reseting.
* Don't know what to do with the /CS1-3 (pins 15,17,19) for chip1-3 selections?
Tried them on all at+5V and all on Gnd without displaying text.
b) Could the Hint1+2 (B.0 and B.1) be switched in @marks his 20X2 LCD driver code with B.4 and B.6 for adding a RotaryEncoder function?
