Can anyone advise please? If, while executing a subroutine an interrupt occurs, is it possible to service the interrupt routine and then, instead of returning to execute the subroutine, simply abort...

Hi to all: I'm looking for a microprocessor trainer that I can program in assembly language, maybe C, and having a usb connection. It would be nice to have a hex keypad on the board as well. ...

I hope someone with some experience with the AD421 can point us forward with a problem we have. We've got an MSP430F149 driving an AD421 16 bit DAC as a 4/20mA current loop driver. The AD421 is...

I am looking to design a current limited, 2-6A, power supply controlled by a PIC. Consumer electronic "smart microprocessor" battery chargers seem to know how to regulate the current. Any thoughts?

Hi I want to find out how fast DMA systems work on embedded systems ? The purpose is to model it in a simulator. So essentially I want to find out (roughly) given x bytes of data how much time would...

I don't want to start a flame war - but need to ask - which would be a good solution to begin PIC programming? This would include not only the chip but the programmer & tools. I would also like to...

Hi all, I am managing a small development team(2 senior engineers + 4 junior engineers). We tend to documenting and weekly code-review. We tend to knowledge sharing and brain-shock. But I can not...

I have to admit to being a bit ignorant about the various types of capacitors available, for example NPO, X7R, etc. I believe these abbreviations refer to the type of dielectric used, which...

What is the smallest (in size, not in computational power or memory) embedded hardware (CPU+USB Host+RS232+RAM+Ethernet+Parallel IO+Optional IDE/ATA) capable of running Linux (preferably kernel 2.6) ?

I'm doing some research on network. I wanna a chip that can capture runt frame in 2 bytes. Is there any suggestion?

Has anyone come across a device which will allow you to replace a standard PC 1.44Mb floppy drive with something which will take CF/SD/MMC cards. It'll need to emulate a floppy drive as there is...

Hello I want to buy a 683xx development kit, a 68302 preferrably. Can anybody tell where I can find/order/buy them online? I checked the Freescale site and found a few but they are very expensive. I...

Hi, I am looking for a small optical scanner to design into a piece of portable equipment. A business card scanner would work, except that the items being scanned are fairly fragile, and feeding them...

I am new to ethernet please be kind. I am looking for information about how to use ethernet in embedded applications. Using a modem for remote data is a simple matter. But when an ethernet and a...

Hi all. I've been working with CAN for years and very good it is too. I currently have a project where we need to implement two micros on one PCB and implementing CAN between them seems the easiest...

Hi all, If a UART baud rate is out by 1.6% will this cause errors? i.e. if the baud rate is 9600 +- 1.6% will a receiver get any erroneous bytes? What about if the receiver has some kind of...

I want to make an embedded system that will display images to a TV or RGB monitor. Let's say a 300ish by 200ish image for example. I'd like to read the image data from an external file (bmp, gif,...
