The main features of the stand-alone mode are:

•

Buttons for transition between different modes

• Speed and brightness control of the patterns

•

Error detection to detect LED failure

After DC input is applied, it starts with brief animation on 4x8 White LED matrix. User can have control over the board only after brief animation.

After brief animation LED matrix will show “ST” flashing. After which user can select different patterns and modes with the help of BCK and FWD button present on the board.

BCK Button: On pressing this button user will switch on to previous pattern or mode.

FWD Button: On pressing this button user will switch on to next pattern or mode. Following are the patterns and modes:

1.

ST flashing pattern

2. Dot sequence pattern

3. ST rolling pattern

4. Wave or curtain pattern

5. Error detection mode

7. ST curtain pattern

User with the help of speed and brightness control potentiometer present on board can control the brightness of LEDs and speed between transitions.

Brightness and speed control: On rotating potentiometer clockwise brightness/speed between transition will increase and vise-versa.

In ST flashing pattern user can control only speed.

All patterns which are mentioned above will be operating under normal mode. In this mode data to be displayed is sent to STAP16DPPS05 through SPI by microcontroller. And by using potentiometer user can change speed and brightness of the pattern.

UM1774 GUI demonstration

4.1

STAP16DPPS05 GUI has two modes. Modes are classified as:

•

Basic mode

• Frame programming mode

The main features of the GUI mode are:

•

Replication of on-board control buttons to select mode itself from the GUI

• Error detection, frequency of performing error detection and error detection representation on 4x8 LED (mapped to 4x8 LEDs on evaluation board) map

•

Adjustable global brightness for all the channels

• Frame programming to display any arbitrary pattern consists of up to 20 frames with variable transition speed

•

4 preconfigured patterns for quick visualization of frame programming mode on the evaluation board

Graphical user interface setup

The Virtual Com Port driver from ST needs to be installed on the PC/laptop for using the

STAP16DPPS05 evaluation board GUI. Please follow the procedure below:

First install the setup (.exe) file on Windows machine. After installing, GUI appears as “LED

Driver Demo” in programs list. Now, if VCP driver is not installed, it can be installed from

…\Program Files\ STMicroelectronics\LED Driver Demo\ST VCP Driver. Both 32-bit version and 64-bit version are included in the setup.

Now, on launching the GUI, first page appears as shown in

Figure 14

. At this point connect evaluation board to the PC and power it up. Now press “Connect”. If GUI identifies the board, it automatically establishes the connection with the board else GUI prompts the user to select the port to which the board is connected as shown in figure below. Choose the port manually and press “Select”. When the GUI is able to interact with the board, message shown is “Port is open”.

Note: To use the GUI, a Windows machine should have Virtual Com Port driver installed. In the picture shown above, COM4 is shown as an example, on connecting USB to the PC, VCOM establishes on any arbitrary port which has to be identified manually if GUI does not recognize the board automatically.

Basic mode has three sections to address different requirements as follows:

• Button control

•

Error detection

• Brightness control for all channels

Figure 15. GUI basic mode

16/28 DocID026418 Rev 1

UM1774 GUI demonstration

While in GUI mode, toggling between preconfigured demos can be handled by buttons in this section. These controls buttons are replication of on board BCK & FWD button.

By the help of GUI buttons on board can be enabled or disabled by pressing Enable or

Disable buttons respectively.

Error detection section demonstrates error (if any) present in the LEDs on 4x8 LED matrix.

Error detection frequency can be selected from three options such as No loop (Error detection is performed once and the results are displayed till any other button is pressed),

0.5 second loop (error detection is performed every 0.5 s by the drivers and the results get updated in real time) and similarly a 1 second loop.

Figure 16. Error representation in GUI

4.2.3 Brightness control for all channel

Brightness of all the channels is simultaneously varied by varying brightness control for all channel slider. Brightness can be varied in 256 steps (15% to 90%) using the slider.

Frame programming displays the feature of demonstrating user-defined patterns in round robin sequence on the evaluation board. This mode contains the set of 20 (maximum) independent frames and each frame represents one instance of representation of LEDs on the board.

In this mode, either the frames can be designed by the user or preconfigured frame patterns can be selected using presets. Transition time between the frames in milliseconds is set by the value in the transition time text box.
