ARDUINO WIRE LIBRARY HANGS INSTALL
ARDUINO WIRE LIBRARY HANGS CODE

I have dug under the library and realized it hangs on the call endTransmission. With the GY-302 it just crashes on calling begin. For most Arduinos, that is 5V Connect GND (black wire on STEMMA version) to common power/data ground Connect the SCK (yellow wire on STEMMA version) pin to the I2C clock SCL pin on your Arduino. Use the same voltage that the microcontroller logic is based off of.

Just be honest, and put a ' you all, WONTFIX' label on it. When I connect them to my arduino though the BH1750 library doesnt work. Connect Vin (red wire on STEMMA version) to the power supply, 3-5V is fine. You think I'm rude ? After 9 years of giving the finger on this issue to the whole community for absolutely no reason, I couldn't care less. Yes, I know, this state is not supposed to happen according to the I2C protocol, but guess what ? electrical glitches didn't get the memo.Ĭountless people, after losing hours or days kind of solved the issue either by making a modified version for themselves, or switching to another library, so there are several implementations of a timeout that are simple and would easily solve the issue.īut arduino developpers stubbornly refuse to fix it !

If the fix was difficult, if it compromised compatibility or added other problem, it would be understandable, but it's not the case, all that is caused by those 2 damn lines of code that obviously can create an infinite loop if for some reason the read operation does not complete : // wait for read operation to complete This runs totally contrary of what arduino is supposed to stand for. library to have real program traces and to find the place where your program hangs. Google shows pages after pages of people getting started and who get discouraged by this elusive bug they don't understand. Adafruit AM2320 sensor library, Arduino library for AM2320 I2C Temp.

e) Next, install the CO2 sensor using a (3/4' NPT. d) Connect the sensor bridge to the Arduino using the male-to-male jumper wires as shown in the wiring diagram. c) Add the sensor bridge and secure it with a screw. It's been 9 YEARS since that bug was first discussed (2011), countless people pulled their hair trying to understand why their Arduino was freezing, why would it work normally, then suddenly stop, a dozen of times, it's been raised in here, dozens of times people had been told to get lost, use something else, etc. b) Mount the Arduino into place and secure it to standoffs with screws.
