Not Telling
Posted by I know what do you mean.
I don't have a netduino but I wanted to get one.
So want to know its performance before I buy one.
Basically I want to drive 64 pixels of RGB LEDs with 8-bit greyscale and 30 frames/sec and I need to decide between AVR32 UC3 and ARM SAM7.
Appreciate your help
Regards
48MHz is 3x faster than 16MHz. GPIO ports may run a bit slower than native MCU instructions...but they will still probably be faster at 48MHz than 16MHz when using native C code accessing memory registers.
If you have a Netduino and a copy of GCC, grab Atmel's SAM7X-EK software examples and put together a quick test using their GPIO "set output" code. You should be able to measure the speed on your oscilloscope (or logic analyzer if it has a high enough resolution).
