USERS GUIDE


Chapter1.Overview 1.1 Welcome Thanks for using the products of 16*2 serial port communication info boards family by Sure Electronics. The product family includes 3 different versions: Edition I, II and III. With larger version number comes more powerful functions. Their basic functions include display system information of your computer, such as Everest status, MBM status (Your CPU temperature, fan/cooler speed, etc.), BBC world news (or any other RSS feeds), WinAmp status (currently playing tracks title, length, position, etc), network status (speed, total bytes, etc), CPU speed, free disk space, memory usage, E-mail details, game status and many others. In addition, users may adjust the contrast ratio of LCD display and backlight brightness. Edition II and III are further developed versions based on the basic functions of LCD Smartie. More features like ambient temperature display, conversion between and , feedback current LCD contrast ratio, backlight brightness level, temperature or product info are added in Edition II. Tips function is available on Edition III based on II. This product provides two different ways of connection: mini USB and 9-pin power cable. Bolts and screws are also provided along with this product so that it can be fixed onto the PC case.

Overview

4. If you select Sure-LCD V1.0as your application A 16X2 sized LCD simulator screen (blue backlight & white character) will pop up like shown in fig 1.11

Fig 1.11

Right-click simulator and select Config in the popped up window and a configuration page will be displayed as shown in fig 1.12. Select COM4 in Com Setting and click Start button to establish a communication. Edition II doesnt provide Edit Memo function like shown in fig 1.13, though Edition III reserves that function as shown in fig 1.14.

5. How to use Tips function: Firstly, select Send Memo to MCU in the drop-down list of Command Group like shown in fig 1.18.


Overview

Fig 1.18 select commands for tips edit

You can edit contents of tips in Edit Memo area like shown in fig 1.19. Each row can simulate the display on LCD, i.e. maximum 16 letters a row (including space) and you are allowed to edit 10 rows at most.

Fig 1.19 Edit tips

Right-click simulator and click Exit in the popup window like shown in fig 1.20. Tips will be displayed on LCD screen soon afterwards.

Tips are displayed progressively and repeatedly like shown in fig 1.20. Interval of adjacent contents is approximately 2 seconds.


Overview

Fig 1.20 a flow simulating the display of tips

Restart LCD Smartie or Sure-LCD, tips display will end. 6. In case the 9-pin power cable is used for the connection with your computer, you need to connect the power cable to J8 on the reverse side of LCD while the other end shall be connected to a 9-pin port of your motherboard, as shown in Fig 1.21. Users may refer to step 1~4 for detailed operations.

Chapter3.Tips for usage

1. This product only supports the communication of D+ and D-, a set of data cable in 9-pin USB. Besides, users need to avoid using mini USB and 9-pin power cable simultaneously for the communication with computer. 2. If the contrast ratio, backlight brightness and displaying contents vary after running LCD Smartie application, it proves that LCD display has successfully received the info from LCD Smartie. 3. The backlight brightness can be adjusted only when the backlight is turned on. Otherwise, the backlight brightness cannot be adjusted once the backlight is turned off. LCD display will turn the backlight off upon receiving the command of Turn backlight off even when the communication is in progress. Therefore, the backlight brightness cannot be adjusted by the slider bar and users need to click Backlight off first and click Backlight On again. Please refer to item 4 in Quick Start for details. 4. Katakana will be displayed if the characters sent by your computer exceed the range of common ASCII code. 5. Please refer to http://lcdsmartie.sourceforge.net/ for more details about LCD Smartie. 6. Do not use LCD Smartie and Sure-LCD simultaneously. 7. Tips will not be displayed once the power is off. If you send newly-created tips to MCU, previous tips will be replaced. 8. You may refer to help of application for use of Sure-LCD.
