-Before to use this example, ensure that you an hyperterminal installed on your
-computer. More info here: https://developer.mbed.org/handbook/Terminals
-
-The default serial comm port uses the SERIAL_TX and SERIAL_RX pins (see their
-definition in the PinNames.h file).
-
-The default serial configuration in this case is 9600 bauds, 8-bit data, no parity
+#include "mbed.h"
+#include "stats_report.h"
+#include "Graphics/RK043FN48H.h"
 
-If you want to change the baudrate for example, you have to redeclare the
-serial object in your code:
 
-Serial pc(SERIAL_TX, SERIAL_RX);
+DigitalOut led1(LED1);
+RK043FN48H display;
 
-Then, you can modify the baudrate and print like this:
 
-pc.baud(115200);
-pc.printf("Hello World !\n");
