I received
my STM32F4 Discovery board few days ago. During these days I am searching for a
good compiler for the STM32 which is free or provide a better code sized free
version. I am already working in .Net environment using C#, and I it is pretty
good. In Google search I saw STM32F4 programming using .Net, the below link.
We are
using a .net port for STM32F4, it is .Net micro framework.
I am using Visual
Studio Ultimate 2010 (Compatibility of others is not known).
I hope
you have an STM32F4 Discovery Board.
Necessary Tools
2.
USB Micro and USB Mini cable.
Install all the softwares.
Step 1
Connect Board to PC using Micro USB
The board will get power and power
LED & COM LED will be on, if your board is fresh the demo program will run
blinking LEDs.
The computer will look for drivers, (
I installed the drivers included in some software already, so i didn’t seen it)
Install STM32 ST-LINK Utility you downloaded. The driver will be
automatically installed.
Step 2
You need to Erase the program and
Configs in the controller.
For these, open the STLink Utility
from where you installed it.
Let’s first erase chip.
From Target select Erase chip ------Target > Erase Chip click Select ALL apply
After doing these you need to erase
sector
For these select erase sector from
target
Target >Erase sector
After these you have to load
bootloader to the Discovery board.
In the
stm32f4 Files.zip you will see some files: Open Tinybooter.hex in the STLink
Utility
From
Targets >Program
After
it’s done,
Reset the
board.
Step 3
After you have reset your board now
plug-in the USB Micro USB and connect to PC(the other USB). Most of the smart
phone cables should be Micro USB. Once
you connected the Micro USB, windows will start searching for driver and will
fail. Now we got to install the driver we downloaded from the zip
file. “STM32_WinUSB_drivers_(for_evaluation_purposes_only) “ Folder. From device manager
find the USB device then (May be its name is STM32F4 Test or unrecognized)
Double click on it, from DRIVER tab
click update diver and browse it to the folder mentioned above and update it.
Doing this you can see a device as shown in
pic. Control Panel> Devices and printers

Step 4
Find the application Named MFDeploy.exe
Launch MFDeploy.exe (you should be
able to find it in C:\Program Files (x86)\Microsoft .NET Micro
Framework\v4.2\Tools\MFDeploy.exe) which you should have got when you installed
the SDK. To make sure MFDeploy can see the board do as shown below.
If you see the Ping the
everything is good till this point. Now download the other 2 .hex ER_Config.hex and ER_Flash.hex files extracted from stm32f4 Files.zip file to the
board using the MFDeploy as shown below one by one. (the Combo-box, you need to change it to USB, the STM Discovey board will be shown in right of it.)
Reset the board.
Step 5
Open Visual
C# Express/ Visual Studio Select the project type as given below
Now we need
to change the properties, so that the Visual Express/Studio will deploy to the
hardware. So change the project properties as shown below
Add
Reference Right Click On MFTest in Solution Explorer>Add Reference> Select the following sown in the figure>OK
Code
using System;
using System.Threading;
using Microsoft.SPOT;
using Microsoft.SPOT.Hardware;
namespace MFtest
{
public class Program
{
public static void Main()
{
OutputPort led1 = new OutputPort(Microsoft.SPOT.Hardware.STM32.Pins.GPIO_PIN_D_15, false); //LED Pins of Discovery Board
OutputPort led2 = new OutputPort(Microsoft.SPOT.Hardware.STM32.Pins.GPIO_PIN_D_14, false);
OutputPort led3 = new OutputPort(Microsoft.SPOT.Hardware.STM32.Pins.GPIO_PIN_D_13, false);
OutputPort led4 = new OutputPort(Microsoft.SPOT.Hardware.STM32.Pins.GPIO_PIN_D_12, false);
while (true)
{
led1.Write(true);
Thread.Sleep(500);
led1.Write(false);
Thread.Sleep(500);
led2.Write(true);
Thread.Sleep(500);
led2.Write(false);
Thread.Sleep(500);
led3.Write(true);
Thread.Sleep(500);
led3.Write(false);
Thread.Sleep(500);
led4.Write(true);
Thread.Sleep(500);
led4.Write(false);
Thread.Sleep(500);
}
}
}
}
ADD files HardwareProvider.cs and CPU.cs to project (step is same as adding reference right click> select Add existing Item) from the zip file downloaded including the drivers.
Start debugging your code will be written to your Discovery, you can see the status at the bottom. Reset your board.
You Are Successfully Done!!!!!!!!!
