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.

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?

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...

Cheap Microcontrollers

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...

Ok, flamewar time I guess. I am looking to explore new microcontrollers because the ones I have under my belt are coming up short for what I need. I have a lot of experience with the 16 series of PICs from Microchip, I have played with basic Stamps (I, II, SX), some experience with Motorola's HC11, HC12 and HC16 series. Currently I use Atmel's AVR (Atmega128) at work. But in trying to b...

Some of you may remember me from the thread I started a month or so ago about building my own keyboard. Well, now I'm up to my eyeballs in the USB and HID specs and AVR datasheets. I've actually got something working using Atmel's AT90USBKey demo board. Now that I'm getting close to knowing what I want to build hardware-wise, how do I go about getting it produced? The AVR microcont...

Hello, Since the Atmel STK500 is much cheaper in the US than in Europe (79USD in the US, around 120EUR in Europa are the prices I found) I'd need a recommendation for a good webshop in the US. Of course it should be cheap ;), reliable. Shipping and handling shouldn't be too expensive (to the US, not to Europe; I'd ex-/import it myself). Thank you very much for any hints and tips!

The NXP LPC1110 starts at less than $1 for a 4KB flash part. That's cheaper than an AVR in my experience! I'm not really sure if it's all that more powerful but it's good enough for me. The thing I like is that it also has a single I/O line debugging, just like AVR's DebugWire, which isn't available on all parts and for which you need to purchase ATMEL's programmer since no one else ha...

Hi @all! I'm using an Atmel 89C51CC02CA. I'm trying to use the Api-functions, implemented in the bootloader. I understood that i first have to write my values to the api_command, api_value and api_dptr (dpl and dph), which is placed in the controllers ram. Then i have to call the codeadress 0xFFF0h. But doing so leads to a reset of the controller. i tried different commands, the result is th...

I was looking at the Atmel AT91R40008 for a new design. However I realised it dosen't support I2C. Does anyone have a recommendation about how to interface a real time clock, and maybe a serial eeprom. Is an I2C bus master a sensible approach, perhaps from Philips? The main objectives are low cost and good availbility. regards, Johnny.
