Hi

Is there a way to access Flash/SRAM memory of ATMega32U4

Please point me to some example.

Thanks in advance

you can dump the contents of the 32u4 flash, but that's what you flashed on it (bootloader + your sketch). I'm not aware of any direct way to access it's memory

on the yun, you can use Bridge shared storage to make your sketch and the outside world share some variables

Hi Federico Fissore,

Thank you very much for the reply. I was hoping more on Bridge.Transfer() function.
Continuing along, can you please point me to some examples on Bridge.Transfer() functionality.

Also, can you help me understand, how AtMega32 Processor talks to Linino other than invoking Process object. I really want to understand to what extent AtMega32 is using Linino resources.

What ArduinoYun health monitoring capabilities we can use. Here is the use case to show my intent

  1. I have 10 Arduinos collecting the data from various sensors
  2. 10 Arduinos sending the data to Remote Database
  3. Small piece of c++ Utility service, which talks to 10Arduinos and check to make sure. 1) Yun linino is running 2) Yun WebServer is running 3) Yun WiFi is running 4) Yun Sketch is running 2) Yun/ Linino memory is still with in threshold.
    Sorry, If I asked, too much. Please point me to some good documentation/articles on this
    Thank you so much
    Again, Thank you

BREL

Well, best place to find all the low level details is the code GitHub - arduino/YunBridge
