Hello, Has anybody already worked with this microcontroller family? Which is your opinion? They seem very interesting because they use an ARM7 core processor and include very useful communications peripherals (ethernet MAC, usb controller, ...) Does anybody know if there are free developing tools: - compiler / linker: i guess that GCC may be useful as this family uses ARM7 cores. - [b...

What do you really use for embedded projects? Do you use "standard" makefile or do you rely on IDE functionalities? Nowadays every MCU manufacturers give IDE, mostly for free, usually based on Eclipse (Atmel Studio and Microchip are probably the most important exception). Anyway most of them use arm gcc as the compiler. I usually try to compile the same project for the embedded target...

HI All I've looked at Keil uVIsion (Trial Version) as well as Asem51v1.3 (old stuff). Any suggestions of the compiler software you're using to write/compile your code and create hex files to upload to the ATMEL microcontrollers. I would rather review a few other options, than to invest in the Keil software, only to discover afterwards that there are maybe better tools for the job ...

I have a product which has been running for 16 years, based on a Hitachi H8/323 (16k PROM, 48k external address space). This CPU is end of life though we can still buy it from Hitachi (Renesas) and countless secondhand chip dealers in the USA :) We are looking at re-doing the whole thing to get rid of the processor. One option is to stick with the H8 family, which still exists, with t...

I'm considering using the Atmel LP214 to act as a translator between legacy hardware and a new imager (camera) chip. It's 14pin, has enough Flash and RAM, and has the UART and counter to make life easy, but I'm a little unclear on how one debugs code on a part like this. I'm not interested in going back to the compile-burn-run puzzle or dropping breadcrumbs (printf-style "begin Main()")...
