ESP8266 Thing #5

Closed hsadeghilam closed 5 years ago

hsadeghilam commented 5 years ago

I'm using ESP8266 Thing with CCS811 and I considering I/O # I made these changes to make the code run.

define D1 14

define D2 2

define D3 5

But I'm getting this error. I have already tried connecting WAKE to GND and 5.

Starting CCS811 simple demo ccs811: begin: reset failed init: CCS811 begin FAILED init: CCS811 versions FAILED init: CCS811 start FAILED CCS811: eco2=65535 ppm, etvoc=65535 ppb, errstat=3F9B=--VHXMRWF--AD-IE=ERROR|OLD, raw6=63 uA, raw10=1023 ADC

Try these. They worked for me

static const uint8_t D0 = 16; static const uint8_t D1 = 5; static const uint8_t D2 = 4; static const uint8_t D3 = 0; static const uint8_t D4 = 2; static const uint8_t D5 = 14; static const uint8_t D6 = 12; static const uint8_t D7 = 13; static const uint8_t D8 = 15; static const uint8_t D9 = 3; static const uint8_t D10 = 1;

Here is the serial output I saw when I dabbed a QTip with 50% Isopropyl Alcohol and took it close to the sensor

Is your sketch working now, @hsadeghilam?

hsadeghilam commented 5 years ago

I really did not get a chance to try this updated library. I actually ended up buying the CCS811 evaluation board from another manufacturer and used their library which worked fine for me!

Ok - thanks for the update. I close the issue.
