I purchased a BME680 module from Sparkfun. I installed it on a breadboard and connected a clone Arduino UNO. The red LED on the board is on so I assume that it has power (+3.3V). When I use pins D18(STA) and D19(SCL) I get
“23:1:26.198 → Starting I2CDemo example program for BME680
23:1:26.203 → - Initializing BME680 sensor
23:1:26.206 → “ and no further activity.
If I use pins D9 and D10 I get
“23:26:53.951 → Starting I2CDemo example program for BME680
23:26:53.955 → - Initializing BME680 sensor
23:26:53.958 → - Unable to find BME680. Trying again in 5 seconds.
23:26:53.961 → - Unable to find BME680. Trying again in 5 seconds.
23:26:58.997 → - Unable to find BME680. Trying again in 5 seconds.”
This continues every 5 seconds.
The program is I2CDemo.
The library by SV Zanishin ver 1,10 - in the Arduino Library Manager,
Is it necessary to have the STA and SCL lines held high - I did not do this as I assumed it was done on the board.
I would appreciate any help.](https://www.myiclubonline.onl/)
