MicroPressure with an AVR-Iot Cellular Mini - Can not connect to sensor

Sensors Environmental
1

The AVR- Iot Cellular board has an onboard Veml13328 light sensor which is I2C and it connects fine. There are some Wire options for this board. MicroChip specifies selecting "2x Wire, Master or Slave (32+ pin devices only). I tried the other options without any luck. Tried specifying the I2C pins in begin.wire also the address 0x18 in the begin.mpr.

Any ideas. Can the MicroPressure I2C be not compatible with the AVR-Iot Cellular I2C?

I can get the MicroPressure to connect to an ESP32 with the library example.

Thanks,

Mike

It looks like that board uses “Two Wire” for its i2c interface with the qwiic port being TWI1 https://www.mouser.com/datasheet/2/268/ … 948951.pdf (pg 18-20)

The schematic on pg 30 also shows the others i2c devices/addresses
