I ran into the same problem some time back, a communication link had a 5-baud initialization sequence where communication parameters were negotiated. Unfortunately we did not find any UART that supported this reliably. So our solution was to use a GPIO pin combined with a UART, implement the 5-baud initialization by sampling the GPIO input and after the negotiation switched the GPIO to high-Z and enabled the UART, now with a supported, high baud rate. Hope this helps.
The first six are all apparently interrput handler conflicts. Here they are (condensed and abbreviated for clarity)...
multiple definition of `_U1RXInterrupt'
multiple definition of `_U2RXInterrupt'
multiple definition of `_U3RXInterrupt'
multiple definition of `_OscillatorFail'
multiple definition of `_AddressError'
multiple definition of `_StackError'
multiple definition of `_MathError'
I'm getting one last error that is totally new to me, this one...
Link Error: Could not allocate section .nbss, size = 20004 bytes, attributes = bss near
Link Error: Could not allocate data memory
I really need
for my assembly language routines.
Can someone tell me how to get the C compliler and MpASM to cooperate and let me have those two ?
I can take out the other interrupts from my assembly language with some text editing.
Your advice and guidance will be greately appreciated.
I reckon the problem stems from your program's design - that is to say, I've heard of mixing asm and C code for decades. I don't recall ever seeing someone put c code into an asm project - it's always the other way around. Regardless of compiler/system, gcc/tc/vs and mips/x86/arm/sparc etc, etc
I'll have another play with it when it's finished installing again.
Mmmm, what version of MPLAB if it's MPLAB X is a <<very bad word>> to set up the project but once you have it is quite good I am told, I have not gone there myself I tend to use MPLAB 8.80. My advice is to download a demo project from Microchip and have a play. If there demo starts to go wrong then them on their board (online, they are quite good usually only had yell once!) You are sure that the assembly is 100% valid on the 24F as there differences in there can't really remember Best of luck!
I'm working on improving a GUI on an application, I have a tabconrol with many pages, I want to put a background Image instead of the unique color which appear behind, I didn't find any property to do it .. Is there any way ?? your help is really appreciated, thanks
So lately I'm having a weird problem with my USB ports. I'll try to explain.
I keep hearing that sound like someone's putting in a flash drive & removing it. Over & over & over. Also, when I look in Windows Explorer, I see a number of "Removable Drives". They must be some kind of virtual drive because I certainly don't have that many pysical drives. They were there when I bought the PC.
At any rate, this problem isn't happening all the time. It just randomly starts. When it's happening, the list of drives in Windows Explorer disappears and reappears at a fast rate in sync with the sound I described.
This is a fairly new PC, and I use AVG and Malware Bytes and scan regularly.
I have a wireless keyboard & mouse, a wireless headset, a printer, and 2 monitors plugged into the USB ports.
I have no clue how to figure out what's wrong. Any hardware people wanna point me in the right direction.
I'm not a hardware-person, but.. if you open the "properties" screen of "my computer", go to "Advanced settings", then to the "Hardware" tab and press the button "Device manager" (or somthing similar, using a silly localized/non English version of Windows atm), you'd launch an app that shows a tree with all the hardware. Try to find the USB-node, and see if Windows tries adding a piece of hardware - there'd be a node appearing and disappearing in sync with the sound.
If you do find one, disable it.
If that fails, download TweakUI and disable every drive that you're not currently using.

Does your computer have a media card reader? If so, that's probably where all those drives are coming from. Each one of those card types has an allocated virtual drive to load to.
Now, to get to your actual problem, it sounds like you're having a problem with some USB peripheral, the drives appearing and disappearing is probably just a symptom of the real problem (i.e. it keeps trying to refresh). The problem can really be anything USB (including your keyboard or mouse) or even one of the USB chips that's malfunctioning (or the power to it is dropping below whatever is it's minimum).
To troubleshoot: - Disconnect ALL external USB items and see if problem appears. - Try to find old style keyboard and mouse to drive. - Disable the media card reader on the device manager if there. - Start in safe mode and see if problem occurs there. - If problem still persists... you'll need more experienced help (need to check voltage levels to USB chips, may be problem with motherboard or powersupply... more likely motherboard since the power to the chips should be going through a regulator on the motherboard).
In system config on the target you need to enable kernel debug specifying firewire of serial.
Hook the target to the host with tht relevant cable.
Turn off the target.
Run windbg on the host and set it to kernel debug on the relevant interface (firewire or serial).
Restart the target and it should connect and you will see a lot of debug data.
You then set the path in windbg for the symbols and code for your driver (and use the global microsoft symbol server for their code, search in help for symsrv), then you can set breakpoints and step through your code.
Everyone might have watched IRON MAN series, in part 2 of the series he uses surface computers containing a transparent glass slab , when i read about the details it was like there were laser-integrated motion sensing projectors which just sensed his hand signal and projected the images but i thought whats the difficulty in implementing a surface comp and i even heard MICROSOFT tried one surface computer which did not succeed
