@byron It is I2C

@inq I could maybe look this up, but why not get the answer from the author.
I have a BME280 which as you likely know does Hum/Temp/Pres. The pins are labelled a little different, but my magic decoder thinks it goes like this.
BME280 to ESP8266
Vin to 3.3V
G to G
SCK to D1
SDO to D2
Does that make sense?
That's a loaded question... The BME280 can be used with I2C or SPI protocols. So you have to choose the right library and configure it accordingly to how you wire it. BMP/BME break-out boards vary greatly. Some have different number of pins 4 to 7 pins.
The four pins ones I used in the past have VIN, GND, SCL, SDA which is for I2C and they go to D1 = SCL and D2 = SDA. I "think" SCK and SDO are SPI interface... Those are pins on the other side of the board.

When I got parts for my students doing the weather station, I wanted to use BME since they do humidity, pressure and temperature. This time around they're expensive... over $14 in 10pcs quantities.
I got the BMP280 and AHT10 for a $1 and $1.70.
Point... don't let the smoke out.

@inq You and @will will be a good pair for finding the least expensive solution. Unfortunately I seem to always find the opposite.

Thanks (I think 🙂

@inq The only remainig pins are CS and SDI. CS is chip select and SDI is to send data TO the BME280 so that leaves Clock which on the 280 is SCK and Data Out which is SDO. Once I resolve the boards problem I will wire this up.

I'm not sure... I think we're being accused of being tight-wads. 😉
I used to buy from China direct and wait a month (or two). I still have fifty or so ESP-01S becoming fine-wine, I got for about $0.79 each. Now... Amazon 2 day rules! At my age, I might forget what I bought them for if I buy from China.

@inq I know what you mean, it is not uncommon to get a surprise at the post office for me.

@inq Now that my computer is working again, I want to get this weather station going. In my board selector it has NodeMCU8266 0.9 (ESP-12 Module) and NodeMCU 1.0 (ESP-12E Module). My board has no info like that, all I can see is 8266MOD. What do you think I should pick?

@inq I am stumped. For a first time test I am using the Adafruit test sketch for the BME280. I have no idea what pins to use on the ESP8266. I am guessing the clock pins go together (SCK to CLK) but where does the SDO go? There is NO pin information in the sketch.

@will I wired it like that and still nothing, plus now I just got another error that I am seeing for the first time. I think it's time for a drink and a break. I am getting too old for this nonsense.

Better make it a double ! That's a very mystic message; I wonder who thought it would be useful to a programmer trying to find out what's wrong ?
