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.
Result when i run the ls command pi@XPO-IOT:~ $ ls -l /dev/ttyS0 crw--w---- 1 root tty 4, 64 Jan 1 1970 /dev/ttyS0 pi@XPO-IOT:~ $ ls -l /dev/ttyS0 /dev/ttyAMA0 /dev/serial0 /dev/serial1 lrwxrwxrwx 1 root root 5 Jan 1 1970 /dev/serial0 -> ttyS0 lrwxrwxrwx 1 root root 7 Jan 1 1970 /dev/serial1 -> ttyA...
From this command what exactly you wanted to suggest me? I replaced file from /dev/serial0 to /dev/ttyS0 and ttyAMA0 in my program but it is showing the same error.
when i run the ls command the command will show the following results. but i didn't understand the groups command. and didn't understand how it will resolve my serial0 problem?? result- pi@XPO-IOT:~ $ ls -l /dev/ttys0 /dev/ttyAMA0 /dev/serial0 /dev/serial1 ls: cannot access /dev/ttys0: No such file ...

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...
