goldelox-md1 based display modules:

description

Goldelox-MD1 is an OLED/LCD graphics controller developed by www.4dsystems.com.au.

	the controller is a generic display controller with RS232 input (important: signal levels between 0V and 3.3V). some data: supports several resolutions support for OLED and LCD panels display informations (resolution, OLED vs. LCD) can be requested from the module. more info: product page at 4D Systems home page disadvantage: rather slow (because of RS232 (limited to max. 256 kbaud)) the module is embedded in some OLED and LCD display modules also provided by 4D Systems.

connecting a GOLDELOX-MD1 based display module:

intro

• the Goldelox-MD1 graphics controller is driven using RS 232 (signal levels: 0V to 3.3V).
   
• NEVER connect the controller directly to a PC-RS232 port! (standard RS232 ports use signal levels from -12V to +12V or -15V to +15V).
   
• better use a USB to RS232 bridge converter. if it uses adequate signal levels it can be connected directly to the Goldelox-MD1 (and also provides power for the controller and the display module).
• Goldelox-MD1 support in serdisplib has only been tested using 4D Systems μUSB-MD5 USB to RS232 bridge converter.
   
• display updates are rather slow due to RS232. a full frame update may need some seconds!
   
• resolution and display technology (OLED vs. LCD) are auto-detected by the library. thus no external setting required. background light is only supported with non-OLED display modules (well, obviously ...)

nota bene

when connecting the controller without using a USB to RS232 converter bridge, replace ttyUSB through ttyS (or similar - depending on the operating system) in the following examples.

examples

configuration in lcd4linux

 Display SerDispLib {
   Driver 'serdisplib'
   Port 'RS232:/dev/ttyUSB0'
   Model 'GOLDELOX'
 } 

configuration in graphlcd

 [serdisp]
 Driver=serdisp
 Device=RS232:/dev/ttyUSB0
 Controller=goldelox

calling test program testserdisp

 testserdisp -n goldelox -p 'RS232:/dev/ttyUSB0'

passing options through serdisp_init():

intro

    examples:
    
      serdisp_init(sdcd, "GOLDELOX", "INVERT=YES");
      serdisp_init(sdcd, "GOLDELOX", "ROTATE=90");
