Finding/Setting CPU speed XSCALE 2hdass5-Nov-05 3:51 2hdass 5-Nov-05 3:51  I am recently writing a small utility for my new axim pda, using c#. In order to retrieve speed information from the CPU, i have to go down to assembly codes in C++. I am planning to write my own dll in C++ and then Pinvoke it in C# to do the job. The problem is, VC C++ doesnt seem to reconize the assembly coes i wrote, it keeps giving me "error C2209: syntax error: "<l_type_ambig>" in the bolded line inline unsigned _Read_CCNT(void) { register unsigned _val_; asm volatile("mrc\tp14,0,%0,c1,c0,0":"=r"(_val_)); return _val_; } I wonder if this is happening because I need a special assembler or something, thx for the info .NET Compact Framework and Diaog Form smoitry3-Nov-05 12:26 smoitry 3-Nov-05 12:26  Hi all, Maybe this forum is more adapted to my question... I want to create a form that will show as a dialog like a MessageBox, I know Windows Mobile permits it as I saw it in other apps, but how can I achieve this using .NET CF ? Thanx, Stephane WM_DEVICECHANGE? Detecting new hardware under WinCE? Roland E.3-Nov-05 2:53 Roland E. 3-Nov-05 2:53  Hi everyone! I would need some message like WM_DEVICECHANGE as for desktops, that tells me that the hardware recently changed. I would like to realize if someone plugged in an USB stick into the WinCE 5.0 device, but there seems to be no windows message equivalent to the one I mentioned above. So what else could I process to get the required information!? I have looked through the MSDN and the net, but I could not find anything so far. Maybe my message is even sent by Windows but it's just not mentioned anywhere in the documentation... (Then I would still need some kind of hardcoded integer, since the compiler does not know anything called WM_DEVICECHANGE ) Any suggestions would be gread, no matter which way has to be gone to reach the new hardware information! Thanks a lot in advance, Roland Re: WM_DEVICECHANGE?

So, if you find an answer I'd be happy to hear about possible solutions and vice versa. regards: Hans Microcontroller programming and interfacing with sonar annp2-Nov-05 21:23 annp 2-Nov-05 21:23  Hey there,,,,,,,,,, im working on cygnal microcontroller C8051F040 and am trying to interface it with a sonar.t program is ready as far as the interfacing is concerned. but while sending the necessary data over the CAN bus to other nodes, i have a slight problem i.e. i can't store data on flash. Can u help me fined some sites where they have sample programs on CAN & FLASH. is there any kind of a clash between FLASH initialisation & CAN ?? I have configured the CAN bus at 1MBPS. sonar runs at 115200 baud. and both the uart's run at 115200 baud. without the FLASH, the data is transferred successfuly to all the other nodes. but with FLASH, the program hangs(if CAN is started.) I also tried disabling CAN before FLASH. doesn't work.. Can nybody help me??

Beginner needs help, any advise welcomed GODSP33D31-Oct-05 16:10 GODSP33D 31-Oct-05 16:10  Hi, This is my first time posting here. I recently got a mobile device and it has made me want to make programs for it. I really enjoy messing and tinkering with it. The reason I want to make a program for it is cause, I think the O/S it has is very stripped down version? It doesn't even have the explorer.exe. So right now i'm using a file management for CE prog. It is running Windows CE 4.2 and I think it uses Compact Framework I see it in the "Remove Program" menu. My goal is to make a Shortcut program for it when it starts up. Basically a program that just calls up other programs. My requirements are: Uses the entire screen No Menu bar or status bar (also no Minimize, restore, and close box at top right) 5 buttons Uses Icons as buttons when buttons are pressed it shows a pressed down state My question is, I don't know almost anything about programming. I do know QBasic and thats it. Could someone please send me in the right direction like the right software required to make this program and reading articles, books, etc that could help me to acheive my goal. Thank you for your time, kim Re: Beginner needs help, any advise welcomed MalikRizwan31-Oct-05 18:56 MalikRizwan 31-Oct-05 18:56  kim it will take time to create a Embedded Application FOR YOU (right now) as you dont have any concept. We (mostly) use .NET for developing embedded applications. i advice you to purchase a Beginner VB.NET Book and try to get some information from MS Compact Framework on the internet .. also there are alot of articles available on Internet for beginners to learn VB.NET and compact framework. the second option for you is to learn about Embedded Visual Basic.

I'll go check out some books at my local bookstore. I talked to someone else and they reffered me to Embedded Visual C++. Can you let me know which program would suite my situation? Thanks again Regards, Kim Re: Beginner needs help, any advise welcomed HarshalP3-Nov-05 1:13 HarshalP 3-Nov-05 1:13  Hi, Embedded Visual C++ is tough for beginners. Instead use .Net Compact Framework, which do the tough job for you and provides a simple to use syntax.

Many times 1 line code is .net is replaced with 10 lines code in VC++. I suggest you to learn VB.NET or Embedded vb.

Jim Wilcox Re: Automatically installing App on a CE device HarshalP3-Nov-05 1:28 HarshalP 3-Nov-05 1:28  Hi Jim, To install the app on Windows CE device from desktop you need to create msi file using .Net Setup Project. Basic idea being, we package the cab file(s) in the msi file and run the msi on desktop. The msi will launch WinCE Application Manager on the desktop that will take care of the installation on the Windows CE device.
