3 Software installation
3.1 Embedded ST-LINK driver installationThe STM3210E-LK box contains the CDs for both IAR and Keil IDEs. You can select either one according to your requirements. The embedded ST-LINK on STM3210E-LK is supported by the IDE from both IAR and Keil and can be used to debug and program the board. Install one of the IDEs by following the steps listed below:
1. Install IAR IDE EWARM or Keil IDE RVMDK from the CDs delivered in the STM3210E-LK box.
2. Select ST-LINK as the debugger in the IDE.
3.2 Demonstration programThe ST CD available in the STM3210E-LK box includes the Demo software and Software library with example programs for some on-board peripherals. It will help you get started quickly with STM32.

12/24
4 Connecting power to the board
To start the demo without any debugging tool, the board must be powered on. There are two ways of doing this.
Note: Jumper JP6 must always be installed in either case.
To run the demo with an IAR or Keil IDE and ST-LINK, the first method must be used. With this method both the on-board ST-LINK and the STM32F103 target MCU are powered by the USB cable connected to the CN1 connector.
Method 1:
Two USB cables are needed when using this power-on method.
1. Place jumper JP1 in position 1-2.
2. Power on the board by attaching a USB cable to connector CN1.
3. After power on, the demo program starts.
4. Then, attach another USB cable to connector CN4 to demonstrate the USB mass storage application.
Method 2:
This method requires only one USB cable. This cable is also used by the USB mass storage application.
1. Place jumper JP1 in position 2-3.
2. Power on the board by attaching a USB cable to connector CN4.
3. After power on, the demo program starts.

5 Operating the demo program
To use the demo, refer to the flowchart in Figure 5 and to the following procedure:
1. After power on, the ST logo is displayed on the LCD
2. There are two LCD demos, you can switch between them by pressing KEY1
3. Press KEY1 once to enter mode 1.
a) The orange LED (LD6) lights up to indicate mode 1.
b) In this mode, you can modify the input voltage to the target MCU’s analog to digital converter by rotating the potentiometer. The converted value is displayed on the LCD.

4. Press KEY1 a second time to enter mode 2.
a) The blue LED (LD4) lights up to indicate mode 2.
b) In this mode, you can operate the joystick.
– First, press in the joystick. A small block ‘cursor’ is displayed in the center of the LCD screen.
– You can move this cursor in 4 directions using the joystick.
– Pressing in the joystick makes the cursor return to the center of the screen. Always press in the joystick before moving the cursor in a new direction.
5. Press KEY1 again to enter mode1 again, and so on.
6. After 5 seconds, if no joystick movement or potentiometer change is detected, the LCD goes into screen saver mode and displays the ST logo. You can still see which mode you are in from the status of the LEDs.
7. A USB mass storage device is also implemented by the demo program with two storage partitions on two different media, one on an SD card and one on external SRAM through the FSMC (flexible static memory controller) of the STM32F103E.
Note: For RVMDK tool users, there are 3 project targets with different configurations that can be chosen freely in the drop-down menu. These are "STM3210E-LK_FULL", "STM3210E-LK-NO_USB" and "STM3210E-LK-USB". The 1st configuration has full functionality and can be used by full version RVMDK users, while the other 2 have limited functionality, as their names suggest, and can be used by evaluation version RVMDK users.
For STM3210E-LK_FULL configuration, all parts in the flowchart are present.
For STM3210E-LK_NO_USB configuration, parts surrounded by the dotted line rectangle on the left are not present.
For STM3210E-LK_USB configuration, parts surrounded by the dotted line rectangle on the right are not present.
UM0621 Troubleshooting
15/24
6 Troubleshooting
6.1 Limitation with reset from IDE during debuggingAs most IDEs (including IAR) only perform a software reset, they cannot reset the MCU thoroughly. After an IDE reset, parts of the board hardware may be in an uncertain state and this may lead to errors in some cases. For example a reset from the IDE may not reset the LCD properly.
Workaround
When debugging with IAR or MDK, to restart debugging without re-programming the chip and by using the IAR or MDK debugger reset:
● Use break to stop the program and reset the program counter (PC) to main and let it run again.
● To do this press the RESET key on the STM3210E-LK board after stopping the program with a break and before making a program counter (PC) reset.
6.2 Analog/digital conversion (ADC) errorsCorrect ADC conversion may be disturbed by USB communication and when an SD card is installed on the board as a removable USB mass storage device. When the SD card is plugged in, this effects the quality of the ADC power source. To prevent this the STM3210E-LK board would need additional on-board filtering and power separation. The demo firmware has a software filtering function, if this is not sufficient, use the workaround described below.
Workaround
Connect power to the STM3210E-LK board using the first method described in Section 4 on page 12. In this case you power on the board using a USB cable on connector CN1 and run the ADC part of the demo before attaching the USB cable to CN4 to run the USB mass storage part of the demo.
