Did some testing with pygame and serial input. 1) Not flushing input gives a very (many seconds) delayed response 2) Flushing gives input errors when part of the transmission is flushed. (Like: 1023 becomes 23) Ok. It worked as I thought Now. How to avoid the problem? Edit: Fixed the problem by lett...

I'm new to programming serial communication so I am guessing from what I managed to understand (misunderstand?) . I thought that continuously write serial data might make the Pi read old data if the ATTiny sends it faster than the Pi reads it. But flushing the receive buffer solves that I assume. Co...

Hi! I have a ATTiny and uses it to read analog input from a sensor and send it through serial communication to the Pi. Now I want to make a program (in Python) that reads the a analog input approx. 30 times per second. What is the best approach to get latest data to the Pi as soon as possible? I thi...

Made Python program that displays a temperature scale from violet to red using a "trick" with HLS hue to easily create the colours in the scale. import time import colorsys from sense_hat import SenseHat sense = SenseHat() #The limits of the temperature scale MAXTEMP = 40.0 MINTEMP = 0.0 #The limits...

Let python write the value to a file and then let php read that file?
I used that solution to get readings from the Sense HAT sensors on a web-page.

Also see this thread on temperature sensors and ambient temperature.

Even after I followed the calibration instructions above I got strange results in my test programs.
But then I found this topic about polling and the IMU sensor:

Using the polling tread solution everything works! Thanks ShiftPlusOne!

Made some tests: Placing the "naked" Pi2+Sense HAT in the room, refrigerator and the freezer I got the following function for temperature: Ta = 0.0071*Tm*Tm+0.86*Tm-10.0 Tm = measured with the temp+humidity sensor Ta = ambient temperature It was running Rasbian+a program reading temperature every 5 ...
