Have successfully brought up the SEPS114A by pasting SPI commands into into a
file named u8g_dev_USMPP19801.cpp with suitable header files. Of course, have
successfully brought up the display with a simple test sketch as well.
However, running the same initialization sequence through u8g_WriteEscSeqP() is
not bringing the device up. Oscilloscope tests seem to confirm at least the CS
pin is toggled during the process, though the timing may be wrong.
This is a rather nice wristwatch-sized full-color OLED module. Would be neat to
properly support u8glib's fonts and graphics support.
Please examine the following code.

Note the rawDispInit() and dispCommand() functions do work in this context when
uncommented.

The text was updated successfully, but these errors were encountered:
The sequence is empty:
tatic const uint8_t u8g_dev_usmpp19801_init_seq[] PROGMEM = {
U8G_ESC_END
};
So it will not work. Also such displays (SSD1351) are better supported by
uCglib.

Thanks for the quick reply!
That sequence is just a commented out empty test sequence. The real sequence is
above, and uses a preprocessor macro to abstract the comm_write() statements.
