How to address it when using multiple grove sensor boards #7

Open alejoduque opened 7 years ago

alejoduque commented 7 years ago

The basic tutorial says: gas.begin(0x04);//the default I2C address of the slave is 0x04

But what if you are using a Seeeduino LoRaWAN board that has 4 inputs? How can I tell what input # is the one located to the outside of the board and what # will have the innermost? There's no clear documentation about this and I will like to use also an OLED and Humidity sensors but have no clue as on how to address them.

Please help with more documentation.

Thanks in advance

Here is LoRa wiki http://wiki.seeed.cc/Seeeduino_LoRAWAN/ . Read this image

I do not fully understand what you mean. But if you want use Grove connector with Gas_sensor.

  1. use digitalWrite(38, HIGH) to open VCC,
  2. plug Grove on I2C port.
  3. Write your code to read data through i2c.

Hey @alejoduque just wanted to see if you had tried it?
