Respberry Pi

I wonder if there is a version of emWin that can run on respberry Pi, similar to the PC simulation. Thanks

Stop notifications until screen is fully initialized

I would like to start getting notifications only after all widgets in a window are initialised. my current solution is to start a short timer at screen build, but I am looking for a more elegant solution. Any ideas? Thanks void do_notification(WM_MESSAGE * pMsg) { WM_HWIN hItem = 0; int NCode; int objIx, wmId; TcObject * pObj ; if(notificationsDisableTimer > 0) return ; // no notification fo a while - need to updat screen first . . . } static void cbScreen(WM_MESSAGE * pMsg) { int i; char * barM...

detect memory leaks

Is there a way to check the current used internal memory of the WM? This is for development time, I wish to make sure that I deleted all "old" windows, so I think that if I can monitor the internal memory usage, I will be able to make sure no garbage windows are there. Any other idea to verify? Thanks Johanan

VNC server efficency

Hi, I am using GUI VNC server, and I can see that it sends all the screen on every small change. Is it possible to configure it so only the rectangles of changes will be sent to the client? For example, if i have a changing display of a counter, instead of sending just the area of the counter it sends all the screen, which is very inefficient. Thanks Johanan

VNC send/rcv implementation

Hello, I am struggling with the implementation of SEND/ RECEIVE function for the GUI_VNC_Process( ..) Can you please clarify: send and receive should be blocking functions? in particular, send should return only after the packet has been completely send ? Should GUI_VNC_Procces be called in an endless loop or just once to set the pointers for the send and receive functions and exits ? My goal is to use VNC via UART to a remote PC, the remote PC has a small service to convert UART data to localho...

Arabic fonts

I find that displaying Arabic is very challenging. Every character can have up to 4 different fonts, depending if it is isolated, start of a word, middle or end of word. The Arabic fonts in the sample file are only for the isolated fonts. Anybody knows how to deal with this? Is there any support for that in emWin? Thanks Johanan

GRAPH DATA DELET

Hi, I need to delete graph data, but I need to check that hG24_a is valid something like: if( isNotFree(hG24_a)) GRAPH_DATA_XY_Delete(hG24_a); how can this be done (checking for hG24_a == NULL does not work as the handle is not NULL) Thanks Johanan

Calender Dialogue mixup.

The Calender dialoge has some mixup erros. 1. The manual: Prototype void CALENDAR_SetDefaultBkColor(GUI_COLOR Color, unsigned Index); but should be probably : Prototype void CALENDAR_SetDefaultBkColor(unsigned Index, GUI_COLOR Color); Also , it looks like CALENDAR_SetDefaultBkColor() is same as CALENDAR_SetDefaultColor() Here is my code, and the output with PC simulation: CALENDAR_SetDefaultFont(CALENDAR_FI_HEADER, &GUI_Font24B_ASCII); CALENDAR_SetDefaultFont(CALENDAR_FI_CONTENT, &GUI_Font24B_AS...

GRAPH free allocated memory problem.

I saw a thread from Ana, with same problem. When I delete a window that has a GRAPH object, I get the message "gui_alloc.c: block to be deleted is already locked in free()". I get this message 2 times, (when I attach 2 graph data, number of times is number of attached data objects) just before the window is deleted: h24Data = GRAPH_DATA_XY_Create(GUI_RED,25,d24Points,25); h24Data1 = GRAPH_DATA_XY_Create(GUI_GREEN,25,d24Points1,25); GRAPH_AttachData(hItem,h24Data); GRAPH_AttachData(hItem,h24Data1...

font converter missing fonnts

If this was the case, then you were correct. unfortunately it is not so. See attached screen with the actual fonts in my PC, compared to the list in the font converter. Since they are sorted , it easy to see. Regards Johanan

font converter missing fonnts

Unfortunately this did not help. //------------ Control Panel\All Control Panel Items\Fonts\Font settings Once the checkbox "Hide fonts based on language settings" is checked, all Windows fonts installed on the computer should be shown in the ’Font’ dialog. //----------------- I also tried running the program in WIN 7 compatibility mode, with same result.

font converter missing fonnts

When I open font dialogue in font converter there is no "Script" combobox, and many fonts are missing. With other programs that use the font dialogue, the font dialogue is full with all available fonts, and the script box is displayed. I tried the demo last version, I am using ST font converter version, it is the same. What is the problem? ( OS windows 8 ) Regards Johanan
