I have a BEng(Hons) in Electronic and Computer Engineering and several years pic, avr and 68k hardware design and test firmware development experience. I want to bolster my formal education in the form of an MSc in the area of Embedded Systems at a UK University. I have found the following options, has anyone completed these courses? know which one has the best reputation? or recommend any ...

Hi, I need to know the size of a function or module because I need to temporarily relocate the function or module from flash into sram to do firmware updates. How can I determine that at runtime? The sizeof( myfunction) generates an error: "size of function unknown". Thanks.

I need to determine the size of a function or module since I need to temporary relocate the function or module from flash into sram for firmware updates. How can I find that out during runtime. The sizeof( myfunction) generates an error saying "size of function unknown". Thanks.

The story so far: I'm trying to reverse engineer a certain much- maligned gaming peripheral from circa 1990. I've already interfaced with it the way microcontroller-God intended and worked out the basic functionality, but I've reached the limits of trial-and-error. There are hidden features that never saw the light of day, embedded deep in the firmware. I can't blackbox them. So I did the onl...

Hi, Is there any difference (hardware-wise) in the "radios" (chipsets) on the AP end of a 802.11b/g/n link and those on the "client" end? I.e., is the difference merely one of antenna gain, Tx power and *firmware* (meaning software that conceivably *could* be rewritten vs. software that is deeply and immutably buried within the chipsets)? Said yet another way, could 'n' PC's with wire...

Maybe a bit off topic, but i'm sure that someone here has good experiences to share. We feel a strong need for a product data management system handling all our engineering data. Besides the 'embedded' related data (hardware,firmware..) we also have a lot of mechanical engineering data generated. (CAD/CAM files..) I know that managing all engineerings data (and even more, the complete...

Hi guys, I need a V23 TX modem firmware running on a PIC microcontroller (75bps transmitter, 450/390Hz FSK). I don't need reception, just transmission, so I guess a PIC will largely be able to do it : A look-up table or DDS-based approach will be ok, but before starting to code it I just would like to check if someone have it already coded... Many thanks, Friendly yours, Robert ww...

Here is the program structure. void main() { Xuint32 countvalue; enable_timer(); // do some stuff on Microblaze ... //some lines of code .... countvalue = readback_timer(); disable_timer(); //send count value back to serial port ... return1; } In short, I am trying to keep tab of how fast va...

I'm making some test with a Freescale MAC7111 on a MAC7100LCEVB. I use IAR as compiler and OSE EPSILON as RTOS. Now I have a project that is compiled righ, but when I upload the firmware to the MAC7111 the program doesn't exit from vector table initalization on CRT0.s79 someone have some idea? ;------------------------------------------------------------------------------ ;- Setup Exceptio...

I often work on embedded firmware for MCUs connected by a multidrop master/slave RS485 bus. Moreover I try to compile the same code with mingw compiler, simulating the hw. Of course, I simulate the serial bus connection (UART) by using a COM port on Windows. This allows me to speed-up testing, debugging and so on. So I can launch many simulators of the same device or different devices...

Howdy All, I just purchased an Evaluation Board from Silicon Labs. Does anyone know where I can get example source code for a Mass Storage class for c8051f320? I have tried the firmware generator from Jungo, but it keeps create an "Unknown Device" Thanks in advance.

Hi, we are using a FT245AM connected USB printer in our embedded machine which is running Linux. For any reason sometimes the device is lost. Since we do not know if it is caused by hardware, printer firmware or operating system I'm looking for people with similar experiences and maybe workarounds. Regards, Klaus

Hi, My company has been investigating the use of soft-core processors (eg. Microblaze, NIOS II) to reduce the risk of having to rewrite firmware due to microcontroller/IC/peripheral obsolescence. In our investigation an interesting point was raised, and I wanted to ask you what you thought about it... ***BACKGROUND*** Our products typically have a production life-cycle of 10-15 years+....

Hi, I have downloaded the srec file through network using TeraTerm in windows 2000 SP4. the first time I downloeded the code, I got the colilo prompt and it was working just fine. now when I reset the board and trying to run the same steps again it displays the garbage data. the following is copy of tera-term output.

Ok, I'm sure this has been beaten to death, but google, etc. found a lot of descriptions of the problem but none of a portable solution. I'm working with some firmware drivers which are intended to be as portable as possible. Data moves thru a switchable 8- or 16-bit data bus chip (a USB device controller specifically). Performance is critical so 16-bit is pretty much necessary. Followin...

Problem ------------------------------------- I am not able to successfully configure MON166 (bootstrap mode) to flash onto my external flash memory so that it communicates properly with my host PC and downloads my target firmware to the external RAM. In fact, when I download the MON166 it gives me an error regarding loss of communication with target. Components on my board ------------...

Hi, I am developing a data logger application for the 18F4550 and was wondering if anyone had some sort of windows/linux application that stored/viewed USB data from the PIC ?? It would be great to get something that works so I cant test my firmware easily... I have built my own basic PIC demo board and I have to decided whether to go with SPP or not..

Hello Folks I am trying to find out some details about writing device drivers . If a device is capable of talking to different IO buses like PCI / ISA / PCI express etc . Is writing a driver to it on a unix / linux system be different If so in what way . To elaborate the question more let us say a particular device could have different firmware on so it can talk to to CPU over different I...
