ATtiny12 is supported by WinAVR but in assembly code only not in C. I have the lastest version, so .... But I've found another solution : a ImageCraft software called ICCTiny. Great for all ATtiny, it support C without problems.

Hi, Somebody knows how programming ATtiny12 in C language because when I compilated my code WinAVR said "ATtiny12 is not supported by the compiler" and I don't enjoy to learn assembler just for a little programm. Thanks.

tomand: Try the compiler WinAVR from http:\\www.avrfreaks.com

Hi, I've a probleme to really understand how works the "Pin change interrupt" on the ATtiny12 from ATMEL. In fact, in the datasheet, I see that ..."The pin change interrupt is triggered by any change on any input or I/O pin. Change on pins PB2..0 will always cause an interrupt. Change on pins...

The receiver is the one ATMEL matched with : the T5744 receiver!

I've seen that but I thought it was weird to give such a range, I supposed if the value changes so much, emitting frequencie changes also and I have to change also the receiver one. Just a last question : what means 20ppm ? Thank you for your help !

I read it but not enough carefully if you say the answer is in there. (and I don't know what do you speak about app note ! I only read datasheet !)

There is only one company which sell the good crystal : Crystek. And the probleme is that it's the only one item I need to buy in Crystek and it will cost a lot for only one item. But I need several other items I found in Digikey (and not in Crystek), which is faster for me !

Hi, I need to use a 13.125MHz crystal for the AT86RF401 transmitter from ATMEL and I would like to know if this value must be respected exactely or can be changed, because I only found a 13.0625 MHz crystal. Thanks

I know it's not a very great resolution but I think it will be enough. In fact,I can't do much better because after I will send information by RF (I need wireless application) and I'm limited by its bandwith (only 5kps).

Hi, I need to use the T5744 RF receiver from ATMEL (matching with the RF transmitter AT86RF401) and I have a question about the demodulator. Into the datasheet, it's written that the T5744 supports various types of protocols and especially Manchester code which interests me (Protocol used by the...

I calculated, and with an acceptable accuracy I fixed myself, a 1MHz clock for the microcontroller will be right.

In fact, my 2 signals (from an ADXL202 accelerometer) are PWM signals with a periode of 1ms. Moreover, the 2 signals are 'synchronized' because they use the same triangle wave reference in the duty cycle modulator. If I am unclear again, here is the link to the application note of Analog Devices...

Hi, I'm looking for an ATMEL microcontroller which can do edge capture input on 2-inputs. I only found some ones which do edge capture on only one input but I need to do this on 2 inputs (I have two signals). Thanks to tell me if that I'm looking for exists.

Hi, I use accelerometers MEMS (ADXL202 from Analog Devices) to calculate velocity of a 4 arms robot. So, I would like to know how I could transmit signals between the robot and PC. I've thought to use (small ... otherwise the MEMS technology doesn't matter ... and low cost) RF wireless but I...

Thanks but I would not use the IRDA protocol. I have just a signal I would like to transmit as fast as I can. I said 4Mb/s because I known its possible with this protocol but without any protocol (just untreated binary signal), what is the limit ? I have not datasheet about my LED so I just want...

Ya, I admit my question is not clear. I just would like to know if I can transmit a 4MHz signal using infrared LED. I mean, LEDs have surely rise time which limits the data rate of transmision ?

Hello, I just want to know what is the nominal range (in average) in emitting frequency for the Infrared LED. I guess if its should be more than 4MHz. Thanks

Hello, I've done acquisition of a mems accelerometer with Labview to make signal processing with Matlab and I've just a little more signal than noise. the fundamental frequence of this signal is normaly around 1Hz and when I make a simple lowpass filter I obtain a strange result : I'd like just...
