General

What is SGTools?

SGTools is an UI development software dedicated for TOPWAY Smart LCD.
SGTools is an upgraded version over the previous RGTools.
It supports all the Smart LCD with resistive touch or capacitive touch.

How many background image can be store in to Smart LCD?

There are 256Mbyte Flash (vary by model) in the Smart LCD
The no. of background image can be preload is depends on the display resolutions (vary by model)
The Smart LCD is showing the interface by PAGE and pages can share the same background image
The maximum no. of PAGE is up to 1000
It should be good enough for most of the UI design.
Smart LCD resolutions No. of background picture
800x600 ~270
800X480 ~330
480X272 ~1000

What kind of image can be use in the SGTools?

Background Image

  • Recommend 24bit BMP
  • Recommend matched resolution image
  • SGTools will resize the un-matched resolution to fit the screen

Icons

  • Recommend 24bit BMP
  • Limit to 1/4 of the Smart LCD display resolutions

Animations

  • Recommend 24bit BMP, Animated GIF supported

USB issue during display project download

Power off Smart LCD

  • Ensure the Smart LCD is totally power off
  • Disconnect the power supply cable of the Smart LCD

Cable issue

  • Use a good quality USB cable
  • Ensure USB power supply(500mA/5V USB supply)
  • A dual USB-A to micro-USB cable, may help in some case

PC USB terminal

  • Try another the USB terminal
  • Connect to the PC motherboard directly (back side of the is better than the front)

Smart LCD cannot be recognized by PC…

Smart LCD USB access locked

  • In case no USB device found on the PC (Smart LCD connected), it is possible than the Smart LCD USB access locked
  • Connect the RS-232 terminal to the PCB
  • In TOPWAY Command Tools, use the “Unlock USB drive” command with the correct password to unlock the USB access

Smart LCD USB access locked (forgot password)

  • In case no USB device found on the PC (Smart LCD connected), it is possible the Smart LCD USB access locked
  • Connect the RS-232 terminal to the PCB
  • In TOPWAY Command Tools, use the “Format USB drive” command to format the USB drive and the USB access will be unlock at the same time

Abnormal USB drive found

  • In case no USB device found on the PC (Smart LCD connected), it is possible the Smart LCD USB drive was corrupted during previous download
  • Use PC format tools to format the drive

Display Project Configuration

How to config the screen saver?

  • To Set the Screen Saver Mode...
  • The Screen Saver Mode can be config in the SGTools Menu ⇒ Tools ⇒ Project Setting

Note. Dim down backlight can further extend the backlight LEDs life.

How to wake up form screen saver?

  • To Wake-up form Screen Saver...
  • Anywhere on screen being touched
  • A page jump command received
  • A data on screen was updated

How to shorten the power up “Starting RTC” time?

Install RTC battery

  • Operate with RTC battery installed can shorten the power up time

RTC Mode Setting

  • The RTC mode can be config in the SGTools Menu ⇒ Tools ⇒ Project Setting

  • RTC Mode as follow
RTC Mode Operating with RTC battery Operating without RTC battery Descriptions
Enable 1st power up takes 6s;

next power up takes 1s

every power up takes 6s RTC run with correct init
Disable every power up takes 1s every power up takes 1s RTC stop
Engineering Mode every power up takes 1s every power up takes 1s RTC run without init

RTC might not run correctly NOT suggest for production setting

UI Elements and Functions

How to calibrate the resistive touch panel?

Power-on Calibration

  • Touch and hold the top-right corner of the RTP
  • Power on the Smart LCD
  • The display will enter the calibrate mode
  • Touch the cross on screen to do the calibration

Command Calibration

  • Power on the Smart LCD
  • Use a E4 command to enter the calibration mode (AA E4 55 AA 5A A5 CC 33 C3 3C)
  • The display will enter the calibrate mode
  • Touch the cross on screen to do the calibration

How to show Value with decimal point?

Integer Value (VP_N16, VP_N32, VP_N64)

  • Data Type can be Signed or Un-signed
  • Config the Integer Digits and Decimal Digits in the Number elements
  • It will show integers with decimal point.
VP's value(10's) Interger Digits Decimal Digits Display Result
15 Auto 3 0.015
23762 Auto 3 23.782
5629 5 1 00562.9
-87913 3 2 -879.13
-13277 2 2 -99.99
1758 3 0 999

Note. Over range value will show its max value

Floating Value (VP_N32)

  • Data Type should be Floating Value
  • Float type value is suggested to select: Integer Digits=Auto, Decimal Digits=1~9. to prevent over maximum value presentation error

Note. Float type value might rounded or truncated due to hex-dec conversion
