Pen plotter as digitizer
Hi, It is possible to use a pen plotter as a digitizer (accuracy may not be as good as a large tablet but an E size plotter takes up far less space than an E size tablet! Trust me, having had *both*! :< ) Skip the HPIB interface (HP Pen plotter. HPIB sucks) but the EIA232 interface should be more than adeq... 16 Dec 2009 17:56

USB HID on ML405/CY7C67300
Hello, I'm trying to implement a simple communication link between my PC and the FPGA. Having read that an HID is the simplest form of USB communication, being a newbie in this, I decided to have a go at that (UART has been done, I figured I could use the challenge, silly me :). Problem's that the documentation f... 16 Dec 2009 09:01

MAX11043 - trying to avoid interrupts at 200kHz...
I'm trying to interface to a MAX11043 (4-channel synchronous ADC with SPI output). It has an end-of-conversion pin, which when active means that a bunch of data is available to read via SPI. Which is fine, except I want to run this baby at 200kHz (ish). Which means that using the EOC pin as an IRQ input is fai... 17 Dec 2009 18:09

ARM Cortex-M3 (Stellaris LM3S811) soft float problem (GCC/QEMU)
Good day, I'm running GCC 4.4.2 (newlib 1.17) cross compiled for target: arm-none-eabi under Linux. I'm testing my small application under QEMU: qemu-system-arm -M lm3s811evb and use Eclipse/GDB to debug the application. I've run into a problem where floating point arithmetic causes the chip to crash. GCC was com... 15 Dec 2009 07:50

Requests for feedback on future AT91SAM9 development kits
I am involved in some internal discussions on how the future development kits for high end ARM products should look like. Have some ideas, but I would be interested in feedback from any users on the current crop of kits. AT91SAM926xEK etc. General comments on this are also welcome. Remember that the SAM9 pr... 18 Dec 2009 20:32

Hi, I need some kind of analysis/report that covers lifetime, production time, market availability, etc. for newer uControllers, e.g. PIC, AVR, ARM, H8, etc. I have googlet a lot, but not found anything useable. Anyone knows about such a report? Thanks in advance, regards Jens ... 16 Dec 2009 10:06

.NET micro framework ... end of embedded world???
What is he future? ARMs are coming down in price. Microsoft has made micro framework license free. Creating firmware has become high level (C#), cheap, and perhaps the next big thing? Will asm/C go the way of the dinosaur? Will 8 bit micros become obsolete? ... 21 Jan 2010 08:53
