Here is a little example that displays your keyboard input on an LED.
/********************************* LED *****************************/ #include#include "EZ.h" static void readStdin(EZ_Input *id, void *data, int fd, int mask) { EZ_Widget *led = (EZ_Widget *)data; char buf[256]; int n; if(mask & EZ_READABLE_MASK) { n = read(fd, buf, 255); if(n > 0) { buf[n] = 0; EZ_ClearLed(led); /* clean up the current action queue */ EZ_QueueLedAction(led, EZ_LED_SCROLL_LEFT, 20000, 1000, buf, ((n&1)? "green": "red")); } } } main(int ac, char **av) { EZ_Widget *led; EZ_Initialize(ac,av,0); led = EZ_CreateWidget(EZ_WIDGET_LED, NULL, EZ_LED_WIDTH, 200, EZ_LED_HEIGHT, 16, EZ_LED_PIXEL_SIZE, 2, EZ_LABEL_POSITION, EZ_CENTER, EZ_LABEL_STRING, "Type in something:", EZ_TRANSIENT, True, 0); EZ_DisplayWidget(led); EZ_AddInput(0, EZ_READABLE_MASK, readStdin, led); EZ_EventMainLoop(); } /**********************************************************************/
