How To Find Hi Speed Usb Port

TheSTM32 Development Board housing theSTM32F103C8 Microcontroller is getting increasingly popular thanks to its ARM Cortex M3 architecture, it has loftier operational speed and more peripheral options. Likewise since, this board can be easily programmed using the Arduino IDE information technology has become a preferable choice for many hobbyists and engineers for quick prototyping.

In our previous tutorial nosotros learnt the basics of the STM32 Development Board and also programmed it to blink an LED. Simply there was one huge drawback with information technology. In guild to programme the Board we utilised a FTDI programmer module and besides had to toggle the boot 0 jumper betwixt and 1 position while uploading and testing a code, which is surely a daunting task. Also the mini-USB port on the Development board was left totally unused. The reason for doing that is, when the STM32 evolution lath is purchasedit does non come with an Arduino ready boot loader and hence the lath will not be discovered by your computer when connected through the USB.

Hopefully though, there exists an experimental kick loader developed byLeafLabs for Maple mini boards. This kicking loader can be flashed into the STM32 once and thereafter nosotros can directly apply the USB port of the STM32 board to upload programs only like any other Arduino boards. Yet this kick loader is nevertheless in developmental stage at the fourth dimension of documenting this tutorial and is not advisable for critical applications. Before proceedings with this tutorial make sure you have read the previous tutorial to understand the basics of this board including details about the specifications and pin-outs.

Now the Arduino IDE is ready to program the STM 32 Blueish Pill Development Boards. Permit us upload the Sample Glimmer Programme from the Arduino IDE to the STM32 Bluish Pill lath to make sure everything is working properly. The instance program can be found at

Open Blink Program from Arduino IDE example

In the example program that opens,nosotros take to make a small alter. By default the program will exist written for PB1 merely on our board the on-board LED is connected to PC13then replace all PB1 with PC13 and we are skillful to keep. Thecomplete case programme which is modified can also be found at the bottom of this page.

The code inside theloop function alone is shown beneath, where nosotros can notice that the PC13 pivot is kept Loftier (on) for thou millisecond so turned LOW (off) for another 1000 millisecond and this is washed for space times since it is in loop function. Thus the LED appears to be blinking with an interval of thou millisecond.

          digitalWrite(PC13, Loftier);   // turn the LED on (High is the voltage level)          delay(g);              // await for a second          digitalWrite(PC13, LOW);    // plough the LED off past making the voltage low          delay(thousand);              // wait for a second

Press the upload button on the Arduino IDE and your programme should get compiled and uploaded. If everything has worked every bit expected then you should run across the following on your Arduino IDE console.

Check console for done uploading

If the Program has been uploaded successfully then you should come across the Light-green LED blinking at a 1 second interval as shown in thevideo below. You tin also fiddle around with the program to increment or decrease the delay.
