hi i am new here. i would like to learn embedded programming on a very well established microcontoller. I know that PICs are becoming more popular but can someone tell me of a controller that is popular in industry for several years (8 or 16 bit) and also has products available that i can use to learn such as demo kits. motorola 68XX? Atmel? 8051? many thanks john

There isn't a way to specify the fuse bit settings of the Atmel AVR as directives in the assembly language program, is there? Have I overlooked something? It seems awkward to have to begin every program with a comment telling me what boxes to check on the STK500 "Fuses" menu.

Hi, I am looking for a 802.11 b/g wireless module to connect a micro controller (atmel mega64) to the network and perform operations using tcp/ip. I found some so far but I am not sure if they are the proper ones. Could you please advice me on any specific products? any constructive post would be more than welcome Thanks in advance Spinaker

Greetings, I am new to JTAG and and I am working on a project that that has an Atmel AVR. I want to be able to use JTAG but have not bought any programming/debugging devices yet. I would like to get something that is compatible with other products that I see myself using in the future such as FPGAs or other microcontroller families. I am on a tight budget and I want to get something tha...

Hi there, Is it possible to use a small portion of the Flash memory during runtime (no JTAG connected) as a persistent storage (instead of using a eeprom). I know it is possible in the ARM from ST but what about the AT91SAM7S from Atmel? Thanks orc

I'm trying to find an ARM chip that has a 32 bit capture timer. I can't find any from Atmel. Does anyone else make such a thing?

Please suggest good emulator for 8051/8052 which support ISP devices(Atmel AT89S series) Thanks Naimesh

I have built the FLIP compatable circuit from the C51_Hardware_Connections.pdf app note (Page 2). But, I always get a time out from the RB2 chip. Has anyone build this circuit successfully? I am using a 32Mhz crystal on the RB2. thanks donald

Hi: Just wondering if any new AVR devices are nearing announcement, or if the ones currently on Atmel's site represent a fairly recent spurt of new developments? I am delighted to see 20MHz offerings in the AVR lineup these days. It has been almost 2 years since I have worked on an AVR project, and now need to make some changes to one. In the process I'm thinking of clearing out ...

Hello all. I have been working with PIC microcontrollers for over 2 years now and I am familiar with and like them. However, recently I have started dabbling with Atmel AVR microcontrollers to see what they have to offer. Especially, since they seem quite popular these days and are showing up in more open-source products. I have done some simple flashing LED circuits with the ATmega8 and 48, ...

Hi all, new here. i have been looking at getting a bootloader to work. all i want to do at this stage is write something to flash so i know it's working and even that isnt working. i got some help from a good friend, who wrote some code for me for his dev board but it was a mega 64. now, that shouldn't really matter, as it had nothing in it that i couldn't use on my 16 other then the registe...

Hello to all of You, Being completely new to AVR's and still studying their "anatomy" and reading about them I have a question that could probably be solved by an experiment but at this moment a real life experiment like this is beyond my capabilities and I am a bit nervous to find the answer because it is important for a plan I have in my head :-). I hope You might be able to give me...

I've just been wading through the Atmel In System Progam PDF files, (mainly trying to catch up on all they things I've avoided) I'm trying to work out, for a new project, the best way for the user to download new system software, though a PC and internet. Currently I use boring old 8051s programed in C, but have used AVR's a few years ago, with the Imagecraft compiler. I could move ove...

I had to replace a flash chip yesterday because it would not read OK at times - and had a byte fail after programming about all the 2M of it. Since I don't do large volumes this is my first ever experience of the kind and I want to ask the group for some insight. The part was an Atmel at49bv163d ; it was on a netmca board which came for repair (torn power cable...) after a few years at th...

I need to know the frequency of a signal that varies from about 1 Hz to 20 Hz. I was thinking of setting up an external interrupt that interrupts when the RPM magnet goes by and to read one of the 3 timers in the processor to compute the period of the signal. Does that sound like the correct way to do this? It seems that I could do something with interrupting the timer directly instead,...

I am quite used to playing with PICs and JAL v2. I use the PicKit3 for programming and debugging. Now I want to learn C and AVR. I thought it may be a good idea to do both at the same time. I already have a device with an ATMEGA168 in it. I want to write my own firmware for this device. I have installed the Atmel Studio 6 and downloaded the data sheet for the '168. Now I need a progra...

I'm still trying to get away from the 8051 with the Raisonance C compiler, which is normally fine for the junk I do. I've got the latest Winavr/GCC and Studio 4 installed, but I getting a bit suspicious of the simulator in Studio 4 when doing stuff in C It's probably me doing it wrong. The simulator/debug seems to miss single stepping through procedures, like my "TwiddlePORTD" routine...

Hi there Sorry for this NewBe question, I?m try o get started in using Atmel AT91RM9200 Board. I've read a lots of how-to and so on. Now running a 2.6 Kernel on it :) I'd like to use a USB video board on it so i think i have to cross compile this driver. My problem i doesn?t find any example through the internet which told me how to do this. Maybe someone could give me some tips. ...

We'd like to use the Philips LPC2114 in a new design (we need 8 capture channels, a serial port etc.), but all the dealers say the lead time is 24 weeks. We can't possibly wait this long to have a pilot series manufactured. Is there any place where we could buy, say 50 of these MCU's _now_ or do we need to use some other chip? I would consider using the new Atmel AT91SAM... chips, but the...
