HI,

I'm playing around with I2C using a Sparkfun ESP32 Thing and Kolbans code for i2cscanning ... cscanner.c)I've got a TMP102 (temperature), HMC6352 (compass), MPL3115A5 (altitude) and a ADXL345 (accelerometer). I've tried hooking up all at the same time, as well as testing them individually. The only device that is found by the i2cscanner.c is the HMC6352 (at address 21). None of the others show up.The boards have onboard pull-up resistors, but I've experimented with adding both 2k2 and 4k7 resistors as well, but no change.Has anyone else tried these (or other) I2C devices with Kolbans i2cscanner?



Please help.

I did not find the right solution from the internet.
