Topic: ADC speed (Read 1 time) previous topic - next topic



I would like to buy an arduino due to make a little oscilloscope. I read that the adc speed of the ┬ÁC is 1Mech/s.
Is it possible to have realy this speed on 2 channels ?

Thanks for help

Although the Due is supposed to give you 1Msps, when you go through the whole stack to make it work it actually margins at 25ksps. There is way (http://arduino.cc/forum/index.php/topic,6549.0.html) for the AVR MCU's to reach faster ADC's but since the Due is based on an ARM architecture, the same won't work. I'm reading the application note (http://www.atmel.com/Images/doc11106.pdf) to figure it out but I'd be happy to hear from you on whether or not you could reach a solution.

Someone has posted a similar lower level code in another thread (http://arduino.cc/forum/index.php/topic,137635.0.html).
