Hello group, For a new project, we have almost decided on AT91SAM7X256 for a variety of reasons. Primarily due to its rich peripheral set and previuos knowledge of Atmel Chips. But we need to implement a LCD display, preferably 320x240 pixels into our system and we would like some advice on the best way to do this. With respect to both hardware and software development. I.e how to get a ...

Hi to all, I work in POS and cash registers design industry since 1995. I use Atmel AVR ATMega128 for almost a decade for the most of my designs. Because of lack of features but mostly because of the rising prices and availability issues recently I decided to move to another MCU (preferably from different brand). I've spent some days looking around and now I am a little bit confused. So,I'd ...

Howdy Group, I'm currently working on a project which requires detecting a PWM train using a microcontroller. The pulse width must be between 800ns and 35us to be considered valid, and the duty cycle must be 1% +/- 2%. Additional requirements are: 1) The uC be in as small a package as possible, something like an 8pin Atmel AVR uC or PIC may do the trick. 2) No external oscillators may b...

Is there any C code for ATMEL's AVR micro controllers to read servo motor position data from a serialport and control 16 RC servo motors simultaneously?

Hello, does anybody know a more powerful Atmel AVR pendant? Is there any 32bit controller that can make a LED blink with only controller, battery, resistor, LED? thanks very much Paul

I've seen plenty of MIPS numbers for ARM, but I'm looking for SpecInt95 SpecFP95 and SpecInt2000 for ARM7TDMI ARM9xxx MPUs, especially for the LPC2000 and atmel microcontrollers. Information for the Xscale chips would be good too. Google hasnt yielded much except a few confusing student papers. Where can I look?

So I was looking through the DigiKey catalog to see how large a serial EEPROM I could get, and found the Microchop 25LC1024, a 128K by 8. I try to order one and was told "August". ??? Damn! So then I try the similar Atmel part, with no luck, then the 32K by 8 chip from both manufacturers too. So who is sucking up all these parts? Or has DigiKey just jumped the gun putting them in their ...

Hello - I'm looking for a small microcontroller that has an onboard CAN controller. If it also had an onboard CAN transciever that would be great - but I've yet to see that in any microcontroller so I'm not getting my hopes up. The problem I've run into is that I'm working on a very small board that needs a CAN interface. Right now I'm planning on using an Atmel AT90CAN128 but I'm early ...

I am designing an Atmel-based circuit with an associated single supply op amp. I do not want the op amp Iq to deplete batteries any further than down to about 1V after the programmed micro brownout. Note that the batteries are not to be manually switched off. What is the simplest way of doing this? Thank you, Henry

I am looking to add a small qwerty keyboard to my project (has an Atmel MCU and LCD). Do not want to use PS2 keyboards. Where can I get a small keyboard (like the one used in handheld organizers/PDAs/databanks)? Hope someone could give me some pointers. Thanks!!

I intend to use WINAVR from Atmel to give instructions to a fan. My computer is fifteen feet from the fan. The target device, a RISC-8 controller, is between. If the fan is to be the one that I've salvaged for this purpose, it has two hot wires and would be governed by either being on or off. Given that I have a hundred bucks to get necessary "software-hardware," what do I need to ...

Hi - so I've gotten to the point where I feel fairly competent with Atmel AVRs (8 bit microcontrollers) - but I'd like to find something with a bit more power. Specifically, I really need a chip that is capable of doing more sophisticated math, ie 16 or 32 bit calculations, multiplication, division, powers, etc. I know some of this can kind of be done on AVRs, but it can't be done well, ...

Ulf, while we have you "on the line," let me ask another thing... Over the weekend I tried out both ImageCraft C and GCC. (With a small program I got very similar results; I didn't try anything big enough to really bring out a difference.) What impressed me is that AVR Studio comes preconfigured for GCC, and once I installed WinAVR (even though I didn't install it in the usual place),...

I have been looking on the web for AVR-GCC example sources on using the ADC converter in the ATmega32 or a related processor, to my disappointment, I have only found the Atmel AVR465: Energy meter example, are there any other examples both simple and complex on setting up and using this peripheral?

My JTAG Cable1 has just failed and I need to get another JTAG programmer, ideally with a USB interface although if it has to be serial so be it. Obviously I'd get an Atmel JTAG ICE Mk11 if the cost wasn't so ridiculously high so it'll have to be an alternative. What are people's views on the best one available at the moment? Thanks. Roger.

Hello again, We've decided to use the Atmel AT91SAM9260 for our project. The chip is probably a bit more powerful than we currently need, but it's always nice to have room for future enhancements, and it's slightly more expensive than most of the ARM7 and Coldfire chips we were looking at. While waiting for my development kit, I'm trying to figure out what development tools and RTOS to u...

I'm trying to choose a microcontroller for a pretty simple control system. It seems like there are about a million models available, so I'm hoping for some help in narrowing down my choices. I've been using the Atmel AT89LP2052, which would be fine except that it doesn't have A/D---it only has a voltage comparator. The device has to be easy to use in a prototype. I guess that means i...

Hi I have a data file which I want to convert into binary, so that I can use a EPROM programmer to burn the image of this data onto an ATMEL flash. Can I do it using fwrite in C?

I'm just wondering if anyone is aware of any > 100MHz 16 bit or 32 processors that are available in QFP packages? I need lots of GPIO as well as SPI and UART ports. I've looked at a couple but it seems to jump from 50-60 MHz general use processors from the likes Atmel and Freescale to > 200MHz processors on par with PDA types of duties which are way beyond what I really need (and tend to be in

Hello there, I'm looking for a very cheap microcontroller indeed. Price point is under 0.35 USD, quantities of 50-100k for first production runs. Application is an RGB LED controller that accepts color information over asynchronous serial communication. I crammed that in an attiny11 pretty easily, but Atmel is discontinuing that model and replacing it with the 2-3X as expensive attiny13! While i...
