Text LCM

If you need text LCM library for simple applications, go to Text LCM Page to get more information.

Graphic LCM

We provide a lot of embedded CPU modules. Besides, we provide graphics/text LCM. Release graphic LCM library in order to reduce develop time for our user. The library is for M6117D CPU only. It's for large memory model under DOS. The LCM we supported now are: 122X32, 128X64, 320X240, 128X128, 240X128, 240X64. The coordinate (0,0) is left-top side. We also provide VGA emulator for programmer has no LCM to test. Programmer can get graphics LCM result on VGA monitor to debug or develop.

LCM library also support Multi-Language: Trad. Chinese (BIG5), Simp. Chinese (GB2312), English, German, Dutch, French, Sweden, Spanish, Greek, Thai, Japanese (SJIS). See the multi-language demo program screen:

What's New

Version 0.27 - 2008/12/08

  • Support printer interface for Vortex86DX serials.

Version 0.26 - 2007/09/05

  • Support printer interface for Vortex86SX serials.

Version 0.25 - 2003/01/06

  • Support busy checking of new 320X240 LCM module (LCM_320X240A).
    New 320X240 LCM support busy checking. User can use this new mode (GPIO only, pin20 connected to GP12) to check busy flag to avoid flicker but display performance will slow down.
  • If programmer use Turbo C/C++ to make GrLCM program, programmer will get some trouble. The compiler we recommend to use our GrLCM library is Borland C++ 3.1.

Version 0.24 - 2002/11/07

  • Fixed: user can use VGA emulator on PC to test LCM function.

Version 0.23 - 2002/10/14

  • Trad. Chinese (BIG5) and Simp. Chinese (GB2312) font file added. Those two font files include all Chinese font that user need not collect all Chinese words.

Version 0.22 - 2002/07/16

  • Multi-Language supported: Trad. Chinese (BIG5), Simp. Chinese (GB2312), English, German, Dutch, French, Sweden, Spanish, Greek, Thai, Japanese (SJIS).
  • GetFont utility added.

Version 0.21 - 2002/07/08

  • VGA emulator added.
  • Vortex86 printer port supported.
  • LCM 240X128 printer port bug fixed.
  • Put image functions bug fixed.
  • Function GrLcm_Close() added.
