Hi everyone, I'm building a rocket flight computer with stabilizing wings and blah blah blah.
But when I tried to add the BMP280 to also have a barometric altimeter, the code didn't work. So I tried running the I2C scanner and it found two addresses: 0x76 and 0x68 (MPU6050). Then I tried running a BMP280 test but that didn't work either.
I tried both 3.3V and 5V and used two different sensors to verify that it wasn't defective, but I still haven't solved the problem.
Does anyone have any ideas? I'm using a nano with optiboot
Perhaps if we knew exactly which module you were using someone would be able to venture an informed opinion. A link to the module in use and a picture would be a good start.
Indeed you did. I wish they were more in focus so I could read the IC markings. However, based on the shape alone, I can now venture a guess as to why the Adafruit library doesn't find a BMP280.
It's likely because you don't have one. That appears to be a BME280 to my eye. And while its address is the same as a BMP280, the programming will be different.
And why it should respond to address 0x68 is a complete mystery. Perhaps it's not even a BME280 but something else entirely. Or you haven't told us the whole story.
Maybe you didn't understand, but the parenthesis next to 0x68 indicated that this address is that of the MPU6050.
Anyway, thanks, I'll try with the BME280 library.
Most new forum members don't say anything, they expect other forum members to somehow know that are using, for example, Nano 33 BLE Sense or whatever. So to avoid wasting time or giving the wrong advice, its best to ask for clarification.
