Is there anything like FastAnalogIn that works with the Nucleo 401 board?

Hi, I'm working on a project (source code for this part is here http://mbed.org/users/flatcat/code/ramanSpectrometer_imagingBoard/ )... I'm trying to read a CCD and either buffer the read into memory and dump it through serial to a PC, or dump is as it's being read... I would really like to use rpc over serial to control the whole thing..but I can't seem to get that to work either..

If anyone has any input on getting the analog signal out of the board fast enough, I'd love to hear it!

Class similar to AnalogIn that uses burst mode to run continious background conversions so when the input is read, the last value can immediatly be returned. AnalogIn, burst, fast

Hi. I also need the port for nucleo (F401 and/or F334). Is the group around the STM32/nucleo boards not interested?

Considering the F401 has an ADC that runs at 4MS/s, I have up till now always assumed that it is so fast that the benefit of something like FastAnalogIn would be limitted. I can have a look at it, but dunno when that is going to happen, got other stuff also :)

Thank you for the answer Erik! I didn't realize it was that fast.. I'm still catching up on it... That's good to know.. I'm actually more concerned about the rpc over serial... Is there any direction you or someone can point me for that? It'd be very much appreciated..!

If I should ask this in a separate question, I'll be happy.. Thanks in advance!

I have never used RPC myself, so hopefully someone else can help you with that. The questions title might not attract those though :)
