sunfounder_sensorkit_for_rpi2's Issues

28_humiture.py convert to F

i have tried putting in temperature = temperature * 9/5.0 + 32 but dont know where exactly it goes.
I keep breaking the script when i put it in
any help is greatly appreciated!

Problem with lcd 1602

30_i2c_lcd1602.py

LCD1602.init(0x27, 1) # init(slave address, background light)
Until this line, all things are fine, because when I change it to LCD1602.init(0x27, 0) background light is closed.
So I think the address and connection is right.

but the characters are not showing on the screen.
Could you please check it？

22_gas_sensor

• Python code: Buzzer works, high values displays danger gas.
• C code: "Saft" is printed, should be "Safe" i guess. Buzzer does not work.

How come Python script says danger on higher numbers while C says safe, C also does not trigger the buzzer. Think there is an issue somewhere in the code.

For anyone having issues, you need to turn the shaft of the pontetiometer to raise and reduce the concentration level, mine was on max and printed 255 all the time. This needs to be turned on the PCF8591 not on the gas sensor. Maybe update this in the description as it was not perfectly clear.

No module named Adafruit_BMP

Hi, I'm using a BMP180 sensor with a Raspberry Pi3 and the sample python program works ok in Python 2, but I get this error in Python 3:

import Adafruit_BMP.BMP085 as BMP085
ImportError: No module named 'Adafruit_BMP'

I'm new this; is it possible to get it working in Python 3? TIA

Hey, insert the Python file PCF8591.py into the webpage Lesson 13: PCF8591!

Please insert the Python file PCF8591.py into the webpage Lesson 13: PCF8591!

The webpage's GitHub file is here!

It took me a while to find the py file and it wasn't even on PyPi.org, so I couldn't even use pip install PCF8591! Put it on PyPi as well!

Good gracious I knew your GitHub! That saved the day for me!

Python 3 support

Would you accept pull requests to make your Python examples compatible with both Python 3 and 2? Security updates for Python 2 in end in 2020, and many key projects have announced plans to drop support in new releases before then. I would be willing to contribute some fixes if you are willing to merge them.

PCF8591 module not found?

Hello, I have this error that I cannot seem to figure out how to fix. I used raspi-config to turn on I2C as well as followed these instructions (https://www.raspberrypi.org/forums/viewtopic.php?f=42&t=14093&p=146643&hilit=PCF8591#p146643) to no avail. It always tells me PCF8591 module isn't found, yet I2C tools sees my PCF8591 as 48. Anyone know why?

Issue to run code getting PCF8591 says no module

import PCF8591 as ADC
ImportError: No module named PCF8591
