If running standard release of debian on my Rpi. How fast can I sample the sensor readings through i2c and save values?
Why Im asking, I tried to read a DS18B20 and save it,s values (wrote the program in python) running xwin and it seems to be very slow.
Right now Im just samplig every 5th second. If I want to measure power readings (AC), they should be done much faster.
Will a C compiled code run much faster?
