Introduction emWin is a graphic library with graphical user interface (GUI). It is designed to provide an efficient, processor- and display controller-independent graphical user interface (GUI) for any application that operates with a graphical display. Figure 1.1-1 emWin runs on N9H26. N9H26 BSP includes emWin related materials, e. g., sample codes, library, documents and tools. We can develop emWin applications on Keil MDK incudes IDE, compiler and debugger (embedded development tools for Arm) to build, modify and debug. We’ll introduce the basic operations on section 2.4. V1.00.007 -4- GUI emWin Start Guide 1.2. emWin Folder structure N9H26 BSP contains emWin related materials and the folder structure is shown below: Directory Name SampleCode \ emWin ThirdParty \ emWin \ Config ThirdParty \ emWin \ Doc ThirdParty \ emWin \ Include ThirdParty \ emWin \ Lib ThirdParty \ emWin \ Tool Content Two emWin samples: 1.

How to update application binary We can update application binary through USB cable to device and here are the steps: 1. Power off device. 2. Plug in USB cable to PC/NB. 3. Keep pressing “Up” and “Down” button. 4. Power on device. 5. After 5 seconds, then release “Up” and “Down” button. 6. Rename application binary to “conprog.bin”. 7. Copy and replace “conprog.bin” to “SD1-1”. 8. Remove USB device safely. 9. Plug out USB cable from PC/NB. 10. Reset device. Here are the pre-built application binaries for SimpleDemo and GUIDemo: SimpleDemo application binary: The path is in “BSP\SampleCode\emWin\SimpleDemo\Bin\” Sample Target Simple_N9H26K5_SD_800x480 Pre-built Application Binary For 800 x 480 LCD with microSD card: SimpleDemo_N9H26K5_SD_800x480.bin GUIDemo application binary: The path is in “BSP\SampleCode\emWin\GUIDemo\Bin\” Sample Target GUI_N9H26K5_SD_800x480 Pre-built Application Binary For 800 x 480 LCD with microSD card: GUIDemo_N9H26K5_SD_800x480.bin Please note that we need to rename application binary to “conprog.bin” before copy to “SD1-1”. V1.00.007 -7- GUI emWin Start Guide 2. Start emWin 2.1. Step 1: Open project Double click “SimpleDemo.uvproj” (the path is in “SampleCode\emWin\SimpleDemo\KEIL”) to open project. Figure 2.1-1 “SimpleDemo” project file. “SimpleDemo” is a sample code to utilize emWin library to demonstrate interactive feature. It contains a frame window, four buttons, a text and a text editor. We can touch the GUI button and check the result that shown on the text editor. The path of “SimpleDemo” is in “SampleCode\emWin”. Figure 2.1-2 “SimpleDemo” sample folder is in “SampleCode\emWin”. The structure of “SimpleDemo”: Blue part is related with BSP. Red part is related with emWin. Figure 2.1-3 “SimpleDemo” project structure. V1.00.007 -8- GUI emWin Start Guide 2.2. Step 2: BSP Initialization In “main.c”, it contains the N9H26 start up flow, e.g., clock setting, timer, uart debug port, display output panel, vendor filesystem and resistor-type touch screen. The path of “main.c” is in “SampleCode\emWin\SimpleDemo”: Figure 2.2-1 “main.c” contains N9H26 start up flow. int main(void) { ... /* N9H26 start up here */ ... /* emWin start up here */ MainTask(); return 0; } V1.00.007 -9- GUI emWin Start Guide 2.3. Step 3: emWin Initialization In “main.c”, called “MainTask()” to start up emWin GUI system. “MainTask()” is in “SampleCode\emWin\SimpleDemo\main.c”: void MainTask(void) { GUI_Init(); CreateFramewin(); while (1) { GUI_Delay(500); } } V1.00.007 - 10 - GUI emWin Start Guide 2.4. Step 4: Build Please note that we suggest to utilize Keil MDK version 5 or above with professional or plus license. To download and run the application, first, we need to utilize Keil to rebuild the application project. Press “[F7]” to rebuild the application project or click “Rebuild”. Figure 2.4-1 Rebuild application project. V1.00.007 - 11 - GUI emWin Start Guide 2.5. Before download and run IMPORTANT!!! We need to configurate ICE setting to download and run. Press “[Alt + F7]” for project options. Figure 2.5-1 Options for target. Choose “Debug” page and select properly ICE, e. g., J-LINK, then press “Settings”. Figure 2.5-2 Select ICE to debug. Set “Speed” (Auto or lower speed), disable “Debug Cache”, then select “Reset Strategy as Hardware, halt after reset (normal)”, finally, click “OK”. Figure 2.5-3 ICE environment setting. V1.00.007 - 12 - GUI emWin Start Guide 2.6. Step 5: Download and run Press “CTRL + [F5]” to download the application and run debug session. After downloaded, it will halt at main() and we should see the similar screenshow below. Figure 2.6-1 Download and run application. Figure 2.6-2 Debug session. V1.00.007 - 13 - GUI emWin Start Guide 2.7. Touch screen To control touch panel, we utilize N9H26 ADC library and open source library “tslib”. The touch calibration results store to a single file called “ts_calib”. The path of “tslib” is in “SampleCode\emWin\SimpleDemo”: Figure 2.7-1 tslib structure. V1.00.007 - 14 - GUI emWin Start Guide 3. Start emWin GUIBuilder 3.1. Step 1: Create widget To create widget, we can utilize emWin “GUIBuilder” to arrange GUI layout and generate source file. The path of “GUIBuilder” is in “ThirdParty\emWin\Tool”: Figure 3.1-1 emWin GUIBuilder. After finish GUI layout, then execute “File” “Save…”, we can get the source file called “FramewinDLG.c”. Figure 3.1-2 emWin GUIBuilder can arrange GUI layout and generate source file. V1.00.007 - 15 - GUI emWin Start Guide 3.2. Step 2: Handle widget event In “FramewinDLG.c”, we can handle widget event, e. g., button clicked, released or others and update text editor’s content when button released. The path of “FramewinDLG.c” is in “SampleCode\emWin\SimpleDemo\Application”: Figure 3.2-1 emWin GUI application source file. ... switch(Id) { case ID_BUTTON_0: // Notifications sent by '+ 1' switch(NCode) { case WM_NOTIFICATION_CLICKED: // USER START (Optionally insert code for reacting on notification message) // USER END break; case WM_NOTIFICATION_RELEASED: // USER START (Optionally insert code for reacting on notification message) value += 1; sprintf(sBuf,"%d ", value); hItem = WM_GetDialogItem(pMsg->hWin, ID_EDIT_0); EDIT_SetText(hItem, sBuf); // USER END break; // USER START (Optionally insert additional code for further notification handling) // USER END } break; ... V1.00.007 - 16 - GUI emWin Start Guide 4. How to change display panel 4.1. Step 1: emWin display “LCDConf.c” defines emWin display configurations. The path of “LCDConf.c” is in “ThirdParty\emWin\Config”: Figure 4.1-1 emWin display configurations. Display panel resolution: In “N9H26TouchPanel.h”, we can modify the “XSIZE_PHYS” and “YSIZE_PHYS” for display panel width and height respectively. Please note that “XSIZE_PHYS” and YSIZE_PHYS” are defined in “SampleCode\emWin\SimpleDemo\tslib\N9H26TouchPanel.h”. ... #define XSIZE_PHYS 320 #define YSIZE_PHYS 240 ... Display buffer address: In “LCDConf.c”, we can assign display buffer address to emWin. Here, we utilize a “Sync-type LCD 320x240”, the display buffer size in RGB565 is 320-width x 240-height x 2-byte-per-pixel = 153600Bytes = 150KB. void LCD_X_Config(void) { ... /* assign display buffer address to emWin */ LCD_SetVRAMAddrEx(0, (void *)u8FrameBufPtr); ... } V1.00.007 - 17 - GUI emWin Start Guide 4.2. Step 2: BSP display N9H26 can utilize VPOST library to output display data to “Sync-type LCD”. N9H26 BSP contains the default display library for 320 x 240 at 16-bit depth RGB565. The path of the default display library is in “Library\IPLib\N9H26_GIANTPLUS_GPM1006D.lib“. Figure 4.2-1 BSP default display library. void LCD_X_Config(void) { ... /* assign display buffer address to emWin */ LCD_SetVRAMAddrEx(0, (void *)u8FrameBufPtr); ... } V1.00.007 - 18 - GUI emWin Start Guide 5.
