Meanwhile I did some more testing on the Listwheel. Previously I assumed that maybe the lack of memory could cause the problems, but I have checked the GUI-Heap fill level and came to the conclusion that this can not be the reason. Creating one Listwheel with 256 Textentries creates in my configuration a heap chunk of ~7KBytes. After creatign four of the listwheels, I still have ~12kBytes of free GUI heap memory. So there is plenty of space left to put some additional entries into a listwheel. I…

Was this problem reroduced or solved in any release? I am experiencing the same problem but slightly different I want to create a listwheel for selection of a IP address. For this I made one const text that contains all the possible elements of one Byte of the IP address. Then I created four listwheel and attached to all of them the same const text by using the function LISTWHEEL_SetText. By doing this the last wheel, the fourth, will not get all of the text elements attached! All wheels show th…

Hi there, I just wanted to tell you that I finally managed to fix my font problem. The solution was an update of STemWin from 5.2.0d to 5.2.2.

Okay let me try to summarize what I tested and which results I got. 1. The read back from the display generally works. Whatever I write to the display GRAM I can read it back exactly in the same way. After another study of the manual this lead me probably to one of my problems. The display controller I use is the Himax HX8352-A, in the emWin manual this controller is not directly listed, there are listet the Himax HX8352 and the HX8352-B. My assumption was that the HX8352 of the manual is the sa…

Hi Adrian, thank you for the quick response. If the memory device option for the corresponding window, that I paint on to, has been enabled, is than still a memory device for the whole LCD required? For my understanding the manual says that by using the memory device option in the window widget will create an own memory device for each window and no memory device for the LCD must be created manually. Nevertheless I will check if reading back the display is working correct. The circle you see on …

Hi, I try to use an aliased font in my application. But as soon as I use it the words get displayed very creepy. As you can see on the screenshot and the photo there are most of the pixels missing and the displayed pixels does not seem to be very aliased. The text is displayed on a window with MemDev enabled, using the text widget. I created the Font using the font creator and exported it in several formats but everytime without luck. I tried to use it as "Antialiased, 2bpp", "Antialiased, 4bpp"…

These functions do not support streaming of bitmaps from non addressable memory. I would require something like ICONVIEW_AddStreamedBitmapItemEx() which does not exist. Another option would be a callback paint function based on items. Then I could paint each item by myself and would not have to paint the whole widget.

Hi there, I wonder if there is a suitable way of displaying an external (NAND-Flash) bitmap as icon in the iconview widget? As far as I have found in the documentation only GUI_BITMAP and streamed bitmaps are supported, correct? If the answer is that I have to overwrite the WM_PAINT event then the widget is out of the game. I mean writing my own widget with that functionality would be much easier than writing a OnPaint function the exisiting one, also because I have no access the to data stored …

The problem was solved by IAR, it was a bug in C-Spy.

Hi, I also created a trouble ticket at IAR but they did not respond with anything helpful yet. I think its more a C-Spy problem, because the debugger must read the flash data from the binary file and pass it to the J-Link api. At first I used the IAR version 6.50.2.4585 but on behalf of IAR I updated to version 6.70.1.5794 which had no positive effect. I already made a test project which is very minimal and shows the fault. Attached you will find the elf-file that is created with the 6.70.1 vers…

This is the log output of c-spy: Source Code (37 lines) Where normally the writing of the code blocks begins is just nothing. When I pass the elf-file to the ielftool by IAR then everything seems to be fine with the file. The tool does not complain about any errors. But also the processed file is not useable for debugging.

Hello, I got a strange error message when I try to load and debug my application. Each time I start debugging the following error occurs: .. 06.11.13 21:40:48 Found 2 JTAG devices, Total IRLen = 9: 06.11.13 21:40:48 #0 Id: 0x4BA00477, IRLen: 4, IRPrint: 0x1 CoreSight JTAG-DP 06.11.13 21:40:48 #1 Id: 0x06413041, IRLen: 5, IRPrint: 0x1 STM32 Boundary Scan 06.11.13 21:40:52 ELF/DWARF Error: Unexpected exception 06.11.13 21:40:52 Fatal error: Unknown exception in driver 8 Session aborted!
