The program works fine with the address assigned to 0x04 (factory setting), I tried to change it using sudo ./gass -a 3c and it did because I have other sensors like MPU-9250 and BMP280 and they stopped working after getting readings from ./gass -s 1. after that change the output shows that the library does not support old V1 firmware (I use a V1 sensor). Where can I change the code to make it work with the new i2c address (0x3c) or how can I restore the original 0x04 address. Thank you
PD (using sudo ./gass -a 04 does not revert the changes nor reseting to factory settings with ./gass -f)

Thanks for your software, it's the only one I found for the RPi, I installed the latest version http://www.airspayce.com/mikem/bcm2835/bcm2835-1.60.tar.gz). I have a BME680 on the RPi and other devices on the I2C bus. I2C search with "i2cdetect -y 1" shows all devices. When I start your software with "sudo /home/pi/gass/gass -A 0x04 -s 1 -n" or "sudo /home/pi/gass/gass -a 0x04 -s 1 -n" all other I2C devices are no longer accessible, values are displayed, but I have to reboot. After that the BME runs until I call your software once. How can this crash be prevented? I ask for help

Hi,

I read your comments at the original repository as well as your document here.
Thanks for all the docmentation you provided.

I built a new board, based on the original Grove board and your remarks. If you are interested, you can have a look at my first blogpost on that.

I will publish the KiCad files and firmware files as soon as possible.
