Second "SparkFun Qwiic Flex Glove Controller - SEN-14666" not detected

Qwiic System
1

Good morning,

I tried to operate two “SparkFun Qwiic Flex Glove Controller - SEN-14666” installed on a “SparkFun Qwiic Shield for Arduino - DEV-14352”, itself installed on a “SparkFun RedBoard - Programmed with Arduino - DEV-13975”. All this programmed with Example2_SetupHand or Example3_Calibration or Example4_ManualCalibration. I get the message “not working”. There is nothing else installed on the “SparkFun RedBoard - Programmed with Arduino”. Individually, the “SparkFun Qwiic Flex Glove Controller” work. I have tried other “Qwiic cables - PRT-14426 PRT-14427 PRT-14429” without success. Same problem with another Arduino controller. Same problem with another “SparkFun Qwiic Shield for Arduino”. I think I have welded the shield well and chained the different elements well.

What to do? Thanks!

Have you changed the address on one of the sensors? Each needs a different i2c address if you are using them on the same qwiic bus.

Look in the hookup guide

for information on changing the address
