== Objective ==
Using Microduino-CoreSTM32 to control the on-board LED. Actually you can learn to how to use the Micrduino-CoreSTM32's I/O port. This is a basic skill you should master and for further study.

== Prerequisites ==

*'''[[Setting Up Maple IDE for Microduino-CoreSTM32]]]'''

== Equipment ==
*'''[[Microduino-CoreSTM32]]'''
Microduino-CoreSTM32 is a 32-bit ARM Cortex-M3 development board, based on STMicroelectronics' STM32F103CBT6.

*Other hardware equipment
**USB Data cable 1(one) piece

== Program ==
*Using delay() function：

<source lang="cpp">
int led = 13;// Define the PIN
void setup() {
pinMode(led, OUTPUT); // Define the I/O port 13 as output
}
void loop() {
digitalWrite(led, HIGH); //I/O port 13 output High. If the connection is high lighted,the LED will light, otherwise extinguished
delay(1000); // delay 1s
digitalWrite(led, LOW); //I/O port 13 output Low.If the connection is high lighted,the LED off, otherwise light.
delay(1000); // delay 1s
}
</source>

*Using function millis()：Return the number of milliseconds from start running Microduino program to now.
<source lang="cpp">
int ledPin=13;
#define TIME 1000
long time1=0,time2=0;
void setup()
{
pinMode(ledPin,OUTPUT);
}
void loop()
{
if(millis()<time2+TIME)
{
digitalWrite(ledPin,HIGH);
time1=millis();
}
else
{
digitalWrite(ledPin,LOW);
if(millis()>time1+TIME)
time2=millis();
}
}
</source>

Using function millis () is better than the delay () function, less resource and fewer delays on the system.

==Download program method==
*Choose the board type in "tools", the "Microduino-CoreSTM32 to Flash" if you want to run the program after reset the board, or "Microduino-CoreSTM32 to RAM" if you just want to test it for one time.

*Compile downloads

[[File:download.jpg|600px|center|thumb]]

==Result==
After the download, you can see LED flashes once every 1s.

+Use the Microduino-CoreSTM32 to control a LED light, and use the Maple IDE to program for the Microduino-CoreSTM32, just like programming in the Arduino IDE.

+This experiment will use the first method, you can try another method.
 <source lang="cpp">
-int led=4;
+int led = 13;              //Define the LED control pin
 void setup() {
-    // Set up the built-in LED pin as an output:
+  pinMode(led, OUTPUT);  //Define the pin as output
+}
 void loop() {
-    digitalWrite(led, HIGH); //I/O port 4 output High. If the connection is high lighted,the LED will light, otherwise extinguished
+digitalWrite(led, HIGH);    //Output higt voltage
-    delay(1000);               // delay 1s
+delay(1000);             // Delay 1s
-    digitalWrite(led, LOW); //I/O port 4 output Low.If the connection is high lighted,the LED off, otherwise light.
+digitalWrite(led, LOW);    //Output low voltage
-    delay(1000);
+delay(1000);            // Delay 1s
+}
 </source>
-*Using function millis()：Return the number of milliseconds from start running Microduino program to now.
+Let's analyze the program：
 <source lang="cpp">
-int ledPin=4;
+int led=13;
-#define TIME 1000
+void setup() {
-long time1=0,time2=0;
+    // Set up the built-in LED pin as an output:
-void setup()
+    pinMode(led, OUTPUT);
+}
+}
 </source>
-Using function millis () is better than the delay () function, less resource and fewer delays on the system.
+Grammatical information：
+togglePin(led)：Swith the specific pin's output value. If the pin is high voltage, then set it to low voltage, otherwise set it to high.
