Hello, I am using the atmel SAM3N00B microcontroller and the only way I can see to do in circuit serial programming is to use the 20 way JTAG connector. However, this connector is too big for our production unit, and I wondered if there is a smaller, say 5 pin programming connector which I could use? SAM3N DATASHEET: www.atmel.c

It looks like you have already started with atmel, so stay with it .. All microcontrollers can do almost the same but the more you practise with a particular type, the more "fluent" you are in it, and the easier for you is to use it in all sorts of applications .. Here you have a PDF file with practical examples on 89C51/2 UART including explan
Yes,Actually it is a USB microcontroller(AT83C5132) from atmel. They have some sample codes...but I want to know how to write PC driver code to recognize the device...How to read the data from Micro controller. I want to write my own device driver... Thanks, Shiva
I have an atmel microcontroller circuit and it is not working I probe the XIN/XOUT lead (crystal input) but could not see a 20mhz signal on my scope.. I checked VDD and ground connector and they are good. Is it a bad chip or is there something else I can check? Thank you D Added after 22 minutes:
Dear All please provide me a simple schematics of Philips 89c52 programmer. better if it is serial programmer (DB9) ( I think this is equal to atmel 89c52 ) your reply is much appreciated.
Hello, Do you know the current consumption of the SAM3N00B microcontroller from atmel? SAM3N00B series datasheet. We have Vcc = 3.3V and we are using the internal 1MHz oscillator. We are using the ADC and the DAC, ..also using one PWM output.
We are using atmel 89c51re2 ic. We want to use the internal SPI in this microcontroller ic. We have connected adc3208 ic which also support spi inteface. We have done pin conncetions for the above setup as below, 89c51re2 adc 3208 sclk(pin 2) sclk(pin 13) mosi(pin 3)
Just stick with the 10MBit soloution, the atmel AT91 isn't fast enough to take advandtage of 100MBit. The highest performance of the fastest atmel AT91 is about 70 MIPS. So you don't gain any speed advantage by using 100MBit instead of 10MBit. You not right, for 100MBit you do not need higer performance than 70 ( really 10-20 M

I need to connect a nokia 3310 to an 8051 controller to send and receive sms. Nokia 3310 uses FBus and MBus protocols. Fbus is bidirectional and operates at 115200 bps. Is it possible to lower the baud rate to 19200 bps/9600 bps to use it with a microcontroller? The MBus protocol is half-duplex and operates at 9600. How do i connect the unidirec
Winavr is the windows port for AVR-GCC. It really is a nice package to get started on the AVR with. It is basically a free C compiler for AVRs that comes with a debugger, a makefile creater, a microcontroller programmer and a Text Editor (close to what you could call an IDE- programmers notepad). ahmad_abdul
