Does anyone know the sampling frequency of the mbed? I am doing the Analogue-to-Digital Converter.

Burst conversion rate is 200KHz. However, you'll have to do it manually using interrupts and hw registers, AnalogIn only does conversion on request.

Here's a sample from Simon Blandford that does it: http://mbed.org/forum/mbed/topic/486/

How can I set the sampling rate to 1KHz?

1Khz should be easily done with a ticker.

How can I find out the actual sampling rate? What is the Burst conversion rate?
