Hi All, Hi Matherp
Few years ago, i tried fast display on MMX144 with buffer RAM, it was working very well, but today, impossible to get it.
I am working with Ver 5.04.18 on MMX144 (may be there is better version at today ?)
OPTION LCDPANEL SSD1963_4_16,L is working well (so PCB, display, connection are ok)
OPTION LCDPANEL SSD1963_4_16_BUFF,L,142 (142, my RD pin) don't work !!
Impossible to remenber how it works ?, using two page ? Display one while charging another one ?
My human EEPROM failed !! please help !!
