HTCC-AB02S not working with basic program CCS811 - Please Help

Veg33 · January 30, 2021, 11:57am

Hi all,

I have been trying to use the " https://github.com/HelTecAutomation/ASR650x-Arduino/blob/master/libraries/LoRa/examples/LoRaWAN/LoRaWAN_Sensors/LoRaWan_CCS811/LoRaWan_CCS811.ino ](https://github.com/HelTecAutomation/ASR650x-Arduino/blob/master/libraries/LoRa/examples/LoRaWAN/LoRaWAN_Sensors/LoRaWan_CCS811/LoRaWan_CCS811.ino" as I decided to buy a CCS811.

Could anyone explain me what pins shall I use? I have seen that it’s using the GPIO0 and GPIO4.

The sensor has the following connections.

@jasonXu Could you help me please?

Thanks.

Take care.

It is GPIO0, and you can modify to your want.

you can also refer this code:

Hi @jasonXu,

Thanks for your help now I can see more clearly but I have another question about this program. What is the GPI04 doing? it just going from low, high and then low.

Thanks for your help.

Kind regards,
