I BROUGHT A NEW RASPBERRY PI 3 BOARD AND USING MY OLD SD CARD WHICH HAS RASPBIAN JESSIE IMAGE FILE. WHEN I SWITCHED ON THE PI 3 AND WANTED TO CONNECT IT WITH THE ROUTER IT WAS SHOWING ERROR AS NO WIFI INTERFACED FOUND. I HAVE DONE 'SUDO APT-GET UPDATE' AND 'SUDO APT-GET UPGRADE' THEN ALSO I AM FACIN...

I have interfaced 7 sensor to I2C bus of Raspberry pi 3 out of which Light and IR (TSL2561) and Gesture (APDS9960) gets conflict because of their I2C addresses. In the datasheet of TSL2561 they have given three options of I2C addresses as if the ADD SEL pin connected to GND then it will select addre...

Whatever settings you told were done and in my program when i change the serial0 file with the ttyAMA0 then the error was not occur but the program didn't show any output on the python shell. So is there any problem in program? Program- import serial # Import Serial library import RPi.GPIO as GPIO #...

So i have to change that file from my program or have to do something else. Because I have done the setting in ras-config as disabled the serial console. Because i am using pi first time and also the python programming.

I'm getting this data form Gyroscope sensor.
Gyroscope [49, 37, 36, 172, 200, 43]

anshumantech

Are you really connecting directly to that chip? Most people would use a break-out module. The connections you describe are not compatible with I2C communication with the Pi. Hello joan, I'm using a break-out module for Gyroscope. pin no 4 RST_B is connected to VDD Now it is compatible with I2C com...
