[QUOTE="cybrmage, post: 219437, member: 51680"] Well... maybe... I have determined that the 0xAD command is used to set the custom characters (Oh... By the way... The display supports custom characters!)... They are used by MHC to display the large numbers that it uses for it's clock display, radio channel display, etc. For the time being, the custom characters are not needed, nor are they used by the driver. so... here is the command set so far: 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 MODEL IDENTIFICATION STRINGS ----------------------------------------- LE2 - M.Play 202 ME4 - M.Play 202 Plus ME5 - M.Play 202 Plus R2 ME7 - M.Play MP300 MP4 - M.Play 202 MP5 - M.Play 202 Plus MP7 - M.Play Blast MR2 - M.Play Blast MZ4 - M.Play MP300 MZ5 - M.Play MP700 (not supported by M.Play Home Center) Regards, CybrMage [/QUOTE]
