BME280 Script error #8

Closed BKeyport closed 2 years ago

BKeyport commented 2 years ago

the script for the BME sensor is using the wrong I2C address, current i2c address for BME280 is 0x77, not 0x76.

Tom-Hirschberger commented 2 years ago

Hi, most of my sensors use 0x76 as address (AZ-Delivery) and require to solder a jumper bridge to use 0x77 as address. I released a new version a view minutes ago which contains a modified bme280 script that supports setting the i2c address as an commandline option. This example should work for your case:

        {
            module: "MMM-Temperature",
            position: "bottom_right",
            config: {
                sensors: [
                    {
                        name: "Sensor One",
                        script: "bme280",
                        args: "0x77",
                    },
                ]
            },
        },

I seem to recall you mentioning adafruit's modules - apparently they have it set to 0x77 by default, then if you jump two pins (SDO and ground) on the board, it'll move to 0x76. I only mentioned the error for those who aren't script savvy (or don't read into Adafruit's docs like I do)

I like your "args" fix. This would be good for any module using qwiic/stemmaQT/i2c - would solve any and all settable parts of HW modules.

Perfect. I will add an additional hint to the readme with some well known addresses.
