I just noticed a nice feature of SAM C2x microcontrollers from Atmel. It is the RS485 support, i.e. one pin (TE) goes high when the UART is transmitting and goes immediately low when the last byte was really shifted out, including stop bits. There is an additional feature that Atmel named "guard time". " For RS485 mode, the guard time is programmable from 0-7 bit times and defines t...

For an application I need to store a large amount of data (ca. 3MB). A serial flash could be a good idea (I don't need to erase very often, and if I erase, I will erase all the data at once). I found Atmel's products. But there is a problem: Atmel produces 2 types of serial flash: Serial Flash and DataFlash(r). What's the difference? Any other suggestion (producer, kind of memory,...) ar...

I'm getting a freebie Atmel NGW100 Network Gateway Kit shortly, and I had a few questions. I plan to use the board to learn embedded Linux, and also learn some other OSs like FreeRTOS and uC/OS-II, and in the process build an adaptive cruise control whose software will run under all three of those OSs. Then I plan to release the whole thing to anyone who wants to build one for themselve...

Hi, as a newbie in this area, I am wondering if I should buy the JTAGICE mkII or the AVR RISP mk II. Is it correct that the JTAGICE mkII can be used for programming *and* debugging all Atmel MCUs, even the AVR32 range?. And, is it correct that the AVRISP MKII is used *only* for programming, and it is not usable for the AVR32 microcontrollers?. Assuming the above ideas are correct, ...

I was somewhat discouraged to find out that putting an external 1Mx16 flash chip on my AT91R40008 board was going to cost more than the 40008 (around $20 in singles from digikey). Then I found the Toshiba TC58FVB160AFT 70ns part from digikey for $3.24 singles/digikey and am happier. Same pinout/package as the atmel part. I think this is a better solution than the AT91FR40162 part in a 121...

The Atmel application note about using the TWI (AVR315 dated 09/04) states that the TWBR should be set to a minimum of 10 and the prescalar should always be set to zero; thus disabling the prescalar. However the data sheet for the mega2561 does not mention either of these restrictions. Has the TWI changed since the issue of the application note or is it simply an omission in the data sheet. ...

We recently based a board on an Atmel AT91SAM9G20 part which the FAE and rep said could boot from NAND flash. The eval board can indeed be configured to boot from NAND flash. However, when it comes time to spec parts for a real product, we find that's all smoke and mirrors. The Atmel SAM9 parts require that block 0 be completely free of bit errors since the ROM bootloader doesn't do ECC (...
