[QUOTE="-Manfred-, post: 398134, member: 50850"] After reading what I wrote earlier post you are right. But I mean any other command than those listed ones. A1 is write line 1, A2 line 2, AF get temp so we are not interested of those. Here are known listed commands: 0xA0 - Clear Screen 0xA1 { 0xZZ - 1 byte of column position data } - Set cursor to line 1, column 0xZZ (where z = 0x00 to 0x13) 0xA2 { 0xZZ - 1 byte of column position data } - Set cursor to line 2, column 0xZZ (where z = 0x00 to 0x13) 0xA4 0x76 { 8 bytes of date/time data } - Set the displays internal clock ?? 0xA4 0x7D - Initialize fan controller 0xA5 { 1 byte of display brightness data } - Set display brightness 0xA7 { 20 bytes of character data } 0x00 - Send data to display 0xAA 0xAA - Identify device. mr300 returns "MZ4", mr700 returns "MZ5" (different command set) 0xAC { 2 bytes of speed data } - Set fan speed 0xAD { 64 bytes of custom character data } - Define custom characters 0xAF - Request temperature readings ?? (returns two bytes of data) 0x00 0x00 0x00 - sync?? break??? 0xA4 0xA4 - ????? part of restart after hibernate 0xA4 0x7E - set power mode to "passthrough" ?????? part of shutdown 0xAE 0xAE - set power mode to "ACPI" ????? part of display shutdown [/QUOTE]
