I am Bruno and I am novice in Python. I need some help on a little project.
I bought a Raspi4 with a grovepi kit.
I tried to read from a sensor with this code:
import grovepi import os pot=1 while True: text_file = open("sample.txt", "w") for z in range(1,50000,1): x=grovepi.analogRead(pot) print(x,z) time.sleep(0.01) text_file.write(str(x)+"\n") text_file.close()
It seems very very slow… If I try to decrease time sleep to 0.005, the code does not start…
I also tried to directly acquire from an arduino instead of the grovepi board and here the sample rate is higher.
Is there a maximum limit of sample/sec that i can read with the grove board?
Thank you very much for your help
