Hi, Oliver,
In fact, with your last help I've compiled good but, now, with U8g2lib nothing is displayed. I've encountered several strange problems. Look:
-
Tests on the same circuit, even with RD always connected to + 5V.
-
Very simple program with the only variations:
#include "U8glib.h" <> #include "U8g2lib.h"
U8GLIB_T6963_240X128 u8g <> U8G2_T6963_240X128_1_8080 u8g2
u8g.drawXBMP <> u8g2.drawXBMP
u8g.firstPage <> u8g2.firstPage
u8g.nextPage <> u8g2.nextPage
PROBLEMS:
a) Frequency has increased noticeably but that should not be a problem.
b) The timing is completely different. While, I believe, with U8glib appears a GLCD initiation cycle, with U8g2, no.
c) Here is the most serious, while with U8glib, the signals oscillate between + 5V and GND, with U8g2, the signals oscillate between + 5V and FLOAT.
Attached timing and oscilloscope displays for each library.
I await your always instructive advice, thanks a lot,
