Hi all, I tried to use the Wiggler compatible JTAG Adapter from Olimex with OCD Commander. Under Win2K it works fine. On my new PC under WinXP it fails. Commander gives the message "Adapter not...

The chip (SIM ?) inside the smart card is considered as firmware? My understanding is that firmware means software on ROM. Or can we say embedded software? I am confused with those terms. Please...

Hi, I used ATMega16 UART to communicate with a target device which is of baud 1200 but failed. I then tried to communicate the UART with PC COM Port and terminal software. I found the communication...

Hi I should implement fire wire for a MPC860 or 8250(motorola) board. Has someone experience with 1394 (firewire) connected with motorola controller? Thanks

Anyone out there try one of these? http://www.coldheattools.com I haven't heard too much about them and would like some feedback before I buy one. Generally, the reviews on the web say good...

We plan on using a GPS PPS signal that will be used to update the internal clock on each net burner (one for each application/sensor). One issue we are currently trying to resolve is how best to...

Hi all, I am in the very early stages of writing a multi-threaded sockets application to enable me to communicate using TCP/IP to several (upto 255) embedded Ethernet controllers in VB.Net. Does...

Hello, I have a board with an embedded PowerPC (mpc8241), on which there is no audio hardware. I want this board to have audio capabilities. I have serial ports, usb ... but no i2s, which is, from...

Hello, I'm developping for a MC68332 board and can't seem to connect to my device with the BDM interface. I'm developping on a laptop running XP connected via the parallel port with a BDM-interface...

Hello, I am trying to use the OV7620 to get a RGB digital output using FPGA Spartan 2 (PEGASUS by Digilent)with the intention to display the image on a regular monitor. The default output of the...

Hi, I'm using a AT89C51ED2. Sometimes the application needs to start the Atmel ISP bootloader, e.g. to enable re-programming the flash. Normally this is done by the following API procedure: void...

I need to find a basic rs232 voice modem for a proof of concept device. The final product will have the functionality built in but for now I need an external solution. The application will generate...

The Motorola/Freescale $25 eval board uses a 78L05, and runs the MCU at 5V. Why, when the data sheet says it expects 3V? Granted the abs max is 6V, but surely they'd want the eval board to run at the...

Maybe a bit off topic but.... Tantalum capacitors are unreliable in power supply applications - this seems to come as a surprise to many people, but believe me it's true Aluminium electrolytics...

I'm looking for a Linux compatible small microcontroller/microprocessor board with the following specs to control a model aircraft * RS232 serial I/O ports (min 2 ports, 115200 Baud) * Parallel I/O...

Hi - I'm attempting to program an AVR so that through a computer (through the serial port) one can easily control how fast it turns on and turns off a single pin. This actually has a use (it will be...
