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_WIFI_INIT_FUNCTION MyWifiStart // Optionally specify if you want to
// use your own wifi startup routine.
// Prototype...
// extern "C" void MyWifiStart(WifiServer *ws);
#define GDISP_GFXNET_WIFI_SSID "ssid" // Your wifi SSID.
// Not required if GDISP_GFXNET_WIFI_INIT_FUNCTION
// is specified.
#define GDISP_GFXNET_WIFI_PASSWORD "password" // Your wifi password.
// Not required if GDISP_GFXNET_WIFI_INIT_FUNCTION
// is specified.
#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 (or Library) add the following lines:
include $(GFXLIB)/gfx.mk
include $(GFXLIB)/drivers/multiple/uGFXnetESP8266/driver.mk
