Customer:
Which are the analog pins on the Dasduino ConnectPlus, and is there a datasheet available for it?
Poštovani, zanima me koji su analogni pinovi na Dasduino ConnectPlus-u, te mogu li dobiti ikakav data sheet za njega ukoliko postoji?

I’m still unsure which of the listed pins are analog. I’ve tried many combinations, but the BME680 sensor still doesn’t work correctly.
I dalje nisam siguran koji od navedenih pinova su analogni, probao sam dosta kombinacija, ali senzor BME680 mi i dalje ne funkcionira ispravno.
Soldered Support:
The BME680 is not an analog device but a digital one that uses I2C communication. Through this communication it is programmed and measurement values are read. You can use our library for the sensor.
BME680 nije analogni uređaj već digitalni, odnosno, koristi I2C komunikaciju. Pomoću te komunikacije se programira te očitava vrijednost mjerenja.
Možete koristiti našu biblioteku za senzor. Nalazi se na link-u.
Customer:
I’m still having trouble with the BME680 sensor and hope you can help. I’m attaching some images to help diagnose the problem.
Poštovani, i dalje imam problema s BME680 senzorom, nadam se da ćete moći pomoći. Šaljem u prilogu par slika za lakše potencijalno otklanjanje problema.

Soldered Support:
From the attached images I can see you have the SCL and SDA lines connected incorrectly.
The SCL line (white wire) should be connected to IO22 pin and the SDA line (blue wire) should be connected to IO21 pin.
Also, is the header on the BME sensor soldered properly? It looks like it may not be soldered at all. If it isn’t soldered, that could cause problems due to poor contact.
iz priloženih slika vidim da ste krivo spojiti SCL i SDA linije.
SCL linija (bijela žica) se spaja na IO22 pin te SDA (plava žica) se spaja na IO21 pin.
Također, je li header koji se nalazi na BME senzoru dobro zalemljen jer mi se čini da uopće nije zalemljen? Ako nije zalemljen, to može isto uzrokovati problem jer nema dobar kontakt.

After soldering the BME680 sensor works, but it doesn’t show correct measurement values. I also want to know if I can use the BME680 and VMA208 module together with a microSD card reader. Do I need a new board with more SDA/SCL inputs since both sensors require them? I’m attaching the code I used and a photo of the connections.
Poštovani, hvala na odgovoru, nakon lemljenja senzor BME680 radi, ali ne pokazuje ispravne vrijednosti mjerenih veličina. Također me zanima ukoliko želim istovremeno koristiti BME680 i VMA208 modul, te microSD čitač kartica, trebam li uzeti novu pločicu s više SDA/SCL ulaza s obzirom da ih zahtijevaju oba korištena senzora? U privitku šaljem korišteni kod i sliku spoja.

Soldered Support:
The connections are correct, but unfortunately the sensor is not very precise - it’s not factory calibrated.
You can adjust the temperature offset in your code.
You can connect all modules to the same I2C communication, but the only requirement is that each module has a different I2C address. Two modules cannot have the same I2C address.
ispravno je spojeno no nažalost senzor nije najprecizniji tj. nije tvornički kalibriran.
Zato postoji mogućnost da postavite odstupanje od temperature u programskom kodu.
Možete spojiti sve module na istu I2C komunikaciju ali jedini uvjet da svaki modul ima različitu I2C adresu. Ne smiju dva modula imati istu I2C adresu.
Customer:
After adjusting the temperature readings are reasonable, but the other deviations are significant. The humidity reading is always 0% or 100%, and the altitude reading is 8000 m which is absurd. Is there a way to make additional adjustments?
Poštovani, nakon prilagodbe temperature očitanja su razumna, no druga odstupanja nisu mala, dapače očitana vlažnost je uvijek 0% ili 100%, a očitana visina 8000 m što je apsurdno. Postoji li mogućnost dodatne prilagodbe?
Soldered Support:
Can you try using our original library without modifications, only adjusting the temperature in your code as you have done?
možeš li probati koristiti naš orginalni library bez izmjena tj. možeš samo prilagoditi temperaturu kako si u svome kodu?
