To use this driver: This driver is special in that it implements both the gdisp low level driver and a touchscreen driver. 1. Add in your gfxconf.h: a) #define GFX_USE_GDISP TRUE b) Optionally #define GFX_USE_GINPUT TRUE #define GINPUT_USE_MOUSE TRUE c) Any optional high level driver defines (see gdisp.h) eg: GDISP_NEED_MULTITHREAD d) Optionally the following (with appropriate values): #define GDISP_SCREEN_WIDTH 640 // Virtual display width #define GDISP_SCREEN_HEIGHT 480 // Virtual display height #define GDISP_GFXNET_UNSAFE_SOCKETS FALSE // Your socket library is not thread-safe // LWIP automatically sets this to TRUE #define GDISP_GFXNET_CUSTOM_LWIP_STARTUP FALSE // You want a custom Start_LWIP() function (LWIP only) #define GDISP_DONT_WAIT_FOR_NET_DISPLAY FALSE // Don't halt waiting for the first connection $define GDISP_GFXNET_PORT 13001 // The TCP port the display sits on 2. To your makefile add the following lines: include $(GFXLIB)/gfx.mk include $(GFXLIB)/drivers/multiple/uGFXnet/driver.mk 3. Make sure you have networking libraries included in your Makefile. NOTE: If you are using ChibiOS with LWIP - you will probably need to increase the default stack size for the lwip_thread. 512 bytes seems too small. 1024 seems to work.
