The mikromedia for STM32

®

development system can be programmed in three different ways.

01

Using the bootloader which is preprogrammed into the device by default or via external programmers (

02

mikroProg

™

or

03

ST-LINK V2

™

) .

Page 13

Programming with mikroBootloader step 1 – Connecting mikromedia

You can program the microcontroller with bootloader which is preprogrammed into the device by default. To transfer

.hex file from a PC to MCU you need bootloader software

(mikroBootloader USB HID) which can be downloaded from:

www.mikroe.com/downloads/get/1849/ mikrobootloader_mikromedia_stm32_v210b.zip

Upon download, unzip it to desired location and start the mikroBootloader application:

01

02

Page 14

Figure 3-3: USB HID mikroBootloader window

01

To start, connect the USB cable, or if already connected press the Reset button on your mikromedia board. Click the

Connect button within 5s to enter the bootloader mode, otherwise existing microcontroller program will execute.

step 2 – Browsing for .HEX file step 3 – Selecting .HEX file

01

01

Figure 3-4: Browse for HEX

01

Click the Browse for HEX button and from a pop-up window (Figure 3.5) choose the .HEX file which will be uploaded to MCU memory.

Page 15

Figure 3-5: Selecting HEX

01

Select .HEX file using open dialog window.

02 Click Open.

step 4 – Uploading .HEX file

After downloading, extract the package and double click the executable setup file, to start installation.

Quick guide

01

Click the Detect MCU button in order to recognize the device ID.

02

Click the Read button to read the entire microcontroller memory.

You can click the Save button to save it to the target HEX file.

03

04

If you want to write the HEX file into the microcontroller, first make sure to load the target HEX file using the Load button.

Then click the Write button to begin programming.

Click the Erase button to clear the microcontroller memory.

In order to adjust the ST-LINK

™

V2 programmer to be connected to the development system, it is necessary to provide the appropriate adapter such as the mikroProg to ST-LINK

V2 adapter. 2x5 male headers should be first soldered on the CN5 connector pads. Then you should plug the adapter into the ST-LINK V2 programmer (2x10 header), and plug an IDC10 flat cable in headers, Figure 3-13

5. Oscillators

STM32F207VGT6 and STM32F407VGT6 microcontrollers are equipped with an internal 16MHz RC oscillator that provides a stable clock signal. Since the chips have an integrated PLL, this base frequency is suitable for further clock multiplication.

Board also contains a 32.768kHz Crystal

oscillator (X1) which provides an external clock for internal RTCC module.

NOTE

The use of crystal in all other schematics is implied even if it is purposely left out, because of the schematics clarity.

6. MicroSD card slot

Board contains a microSD card slot for using microSD cards in your projects. It enables you to store large amounts of data externally, thus saving microcontroller memory. MicroSD cards use Serial Peripheral Interface (SPI) for communication with the microcontroller.

On board ADXL345 accelerometer is used to measure acceleration in three axes: x, y and z. The acceleromer’s function is defined by the user in the program loaded into the microcontroller. Communication between the accelerometer and the microcontroller is performed via the I2C interface.

Page 34

You can set the accelerometer address to 0 or 1 by re-soldering the SMD jumper (zero-ohm resistor) to the appropriate position. Jumper is placed in address 1 position by default.

Pads HDR1

Most microcontroller pins are available for further connectivity via two 1x26 rows of connection pads on both sides of the mikromedia board. They are designed to match additional shields, such as Battery Boost shield, Gaming, PROTO shield and others.

15. mikromedia accessories

We have prepared a set of extension boards pin-compatible with your mikromedia, which enable you to easily expand your board’s basic functionality. We call them mikromedia shields. But we also offer other accessories, such as a Li-polymer battery, stacking headers, wire jumpers and more.

16. What’s next?

You have now completed the journey through each and every feature of mikromedia for STM32. You got to know its modules and organization. Now you are ready to start using your new board. We are suggesting several steps which are probably the best way to begin. Find useful projects and tutorials on the Libstock website (www.libstock.com). Join our Forum (www.mikroe.com/forum) and get help from a large ecosystem of users.

Compiler

You still don’t have an appropriate compiler? Locate ARM compiler that suits you best on our site:

www.mikroe.com/arm/compilers

Choose between mikroC

™

, mikroBasic

™

and mikroPascal

™

and download a fully functional demo version, so you can begin building your first applications.

Visual TFT

Once you have chosen your compiler, and since you already got the board, you are ready to start writing your first projects. Visual TFT software enables you to quickly create your GUI. It will automatically generate code compatible with МikroElektronika compilers. Visual TFT is rich with examples, which are an excellent starting point for your future projects. Download it from the link bellow:
