Guys i just released an DAQ system based on Arduino Uno or Mega that overcomes the RAM limitation of the processor and of the all the other Arduino DAQ that i found on the net with the acquisition of 2000/8000 samples at cycle. I also develop a small Python GUI that simulate a digital oscilloscope.
The main characteristic of the system are:
- 1 Channel
- Sampling frequency (max) 76.9 kHz
- Resolution 8 bit
- 2000/8000 samples at each time
- Free Run mode or Trigger mode with the trigger level, trigger delay and trigger edge configurable by serial commands
All the details can be found here
Enjoy!
