Hallo audiocommander! The display is http://www.reichelt.de/index.html?SID=17d-bY7awQARIAAG-oNuIc7e190ee17f19f3bf80f02dd19e32274;LASTACTION=3;SORT=artikel.artnr;WG=0;SUCHE=lcd;ARTIKEL=LCD%20162C;START=0;END=16;FAQSEARCH=LCD-MODUL%2016X2;FAQTHEME=-1;FAQSEARCHTYPE=0;STATIC=0;FC=669;PROVID=0;TITEL=0;ARTIKELID=31652;FAQAUTO=1;ACTION=3;GRUPPE=A5211 The alternative display is from the same type but with LED background lighting. Do you know the debug tool from MIOS Studio? It has a LCD writing test. It is possible to clean the display but it is only possible to write one character. (the first one in this case) I havent tried an other code possion to write on the display yet. Could it be a timing issue?

Hallo! I have a strange problem. The display (2x16 from reichelt) did not work properly. It seem that the cursor shift did not work. During startup it shows only "MI", not "MIOS". If I had loades an example application like midibox64 the display shows random characters in the first two columns in both rows. ------------------------- eo or ------------------------- I just played around with the c-"Hello World!"-Programm. (BTW: very great that c is supported now) void DISPLAY_Init(void) __wparam { MIOS_LCD_Clear(); MIOS_LCD_CursorSet(0x00); MIOS_LCD_PrintCString("Thomas"); } -> the Display shows ------------------------- s ------------------------- But positioning each character works. void DISPLAY_Init(void) __wparam { MIOS_LCD_Clear(); MIOS_LCD_CursorSet(0x00); MIOS_LCD_PrintCString("T"); MIOS_LCD_CursorSet(0x01); MIOS_LCD_PrintCString("h"); MIOS_LCD_CursorSet(0x02); MIOS_LCD_PrintCString("o"); MIOS_LCD_CursorSet(0x03); MIOS_LCD_PrintCString("m"); MIOS_LCD_CursorSet(0x04); MIOS_LCD_PrintCString("a"); MIOS_LCD_CursorSet(0x05); MIOS_LCD_PrintCString("s"); } -> the Display shows ------------------------- Thomas ------------------------- I changed the display -> same effect. So it should not be the display. I checked all wiring -> all seems ok, no shortcuts etc. no mismatched wires. But I assume it must be a connection problem. I read the datasheet of the display. And there should be no combination that couses this effect. If one dataline is wrong the characters should be as well. I cannot remember that a wrong character was written. Only the shifting seems to fail. Any Ideas?
