I am attempting to read voltage levels from the ADS1015 by connecting it through Qwiic cables to an OpenLog Artemis, which is returning “Known I2C address but device failed authentication at address 0x48” and will not recognize the ADC. This part is listed as supported on the Openlog Artemis so is there anything that can be done? The OpenLog seems to work correctly with the Qwiic scales I have purchased as well as the internal IMU. I read in a thread that I can no longer find that it might not be recognized if there is no voltage input on the ADC, so I tried resetting it with both 3.3V on A0 and 2.5V differential A1/A0. The problem persists weather or not I use a Mux, the serial output just repeats the error more frequently.
How many sensors are on the i2c bus/how long are the cables? Also please share a photo of the set-up & wiring
What happens if you only put one ADS1015 on the bus?
Similar result here. Using 5cm cables, same result with or without quickmux.
Serial reports back
Identifying Qwiic Devices…
Known I2C address but device failed identification at address 0x48
Autodetect complete
Tried changing i2c power and speed settings to no avail. Tried flashing OpenLog_Artemis-V10-v22 firmware with same result. Getting ready to solder different address jumper to see if that results in different outcome.
Any other suggestions greatly appreciated.
Flashed Artimis with V10-v25, now working.
