What is Mbed
The mbed development platform is the fastest wa to create products based on ARM
microcontrollers.
The project is being developed b ARM, its Partners and the contributions of the global
mbed Developer Communit .
In practice Mbed is online compiler tool.
This means that to use it, it is necessar to have a Internet connection.
More info are here.

Update the FW on NUCLEO-L152RE
•First install the ST-Link driver (st inknuc eodriversigned.zip)
•Next go here and download the FW update (st inkv2m4upgrade.zip).
ST-Link driver Insta ation
1. Extract (st inknuc eodriversigned.zip) and run either dpinst_amd64.exe (for 64bit
PC) or dpinst_x86.exe (for standard 32bit PC) depending on whether ou are on a
64bit machine.
2. Follow the prompts
FW update
Connect the NUCLEO-L152 to the PC and extract and run (also with ADMINISTRATOR
privilege) ST-LinkUpgrade.exe (st inkv2m4upgrade.zip) and follow the prompts, see
below.

SW examp es
To use the NUCLEO-L152RE Mbed examp es ou must before register on mbed and:
add the p atform to your compi er, chose ST NUCLEO L152RE, see below.
Now we need to use the example: Nuc eo_read_button
for do this, select it, see below.

A minimum debug using pc.printf
Up to now it is not present a serious debug tool in Mbed, the onl possibilit that ou have
is to use the pc.printf or printf that sends a message (text, variable, etc) via USB port to
the PC.
The PC see the NUCLEO-L152RE as a Virtua COM Port.
To check if the Virtua COM Port is installed correctl on Windows 7, follow the
instructions below.
Select: START -> Device and Printer
You must see something like below.
Now select the STM32 STLink and c ick on it using the right button of the mouse.
From the window that appears, select Properties, see below.

To check if the Virtua COM Port is installed correctl on Windows XP , follow the
instructions below.
START → Impostazioni → Panne o di Contro o
From Panne o di Contro o select Sistema, see below.
From the new window that appears, select Gestione Periferiche and a new window
appear. From this window select Porte (COM e LPT), see below.

Now use the example Nuc eo_printf and programing our Nuc eo-L152RE.
Below there is the content of main.cpp
#include "mbed.h"
//------------------------------------
// Hyperterminal configuration
// 9600 bauds, 8-bit data, no parity
//------------------------------------
erial pc( ERIAL_TX, ERIAL_RX);
DigitalOut myled(LED1);
int main() {
int i = 1;
pc.printf("Hello World !\n");
while(1) {
wait(1);
pc.printf("This program runs since %d seconds.\n", i++);
myled = !myled;
}
}
Configure our TeraTerm (on Windows 7) using the following parameters:

How to use ST-Link-Uti ity
The STM32 ST-Link Utilit software facilitates fast in-s stem programming of
the STM32 microcontroller families in both development and production
environments via the ST-Link tool.
The reference page is:
http://www.st.com/internet/evalboard/product/251168.jsp
This tool is compatible with ST-LINK and ST-LINKv2.
To update the firmware on ST-Link select the menù show below.

Update the USB driver for ST-LINK-v2
NOTE:
Do this update onl if the: Update the FW on NUCLEO- L152RE fails.
Update the usb driver for ST-LINK-v2, chose it from the list below.
STSW-LINK003 ST-LINK/V2 USB driver for Windows 7, Vista and XP
STSW-LINK006 ST-LINK/V2 USB driver for Windows 8
Unzip the file and run it, with the privilege of ADMINISTRATOR, the file is:
st- ink_v2_usbdriver.exe
If the USB drive is a ready insta ed on our PC, first remove it (Fig.1) and next re-install
it (Fig.2), see below.
Fig.1 – remove the previous insta ation
