Hi everyone, I'm trying to acquire a temperature from a MCP9808 sensor with a B-L072Z-LRWAN1. But I got an "onRxTimeout" error everytime I try. Is someone knows why ? Thank you a lot for helping me.

 I'm using stm32cubeIDE and I got nothing more than the STM32CubeExpansion_LRWAN_V1.2.1's libraries (stm32l0xx_hal_i2c) to help me. I'm on the i2c1 interface on PB8 and PB9 ports. I think the problem is that I don't know how the flags works.

VL53L1X range readings not accurate after 200cm

We are testing VL53L1X Time of Flight Sensor with STM32L072(B-L072z-Lrwan) controller. Within 200cm the range measured by sensor is accurate. After 200cm we are getting a lot of variation in the range is measured by the sensor. We have to change the ...

VL53L1 Accuracy Issue

Posted on June 19, 2018 at 14:12HiWe have interfaced VL53L1 to STM32L0 EVM board(B-L072Z-LRWAN1).We tested the sensor with a white surface and water in opaque object.The accuracy with white surface are good if the object is below 200cm.If above 200c...

Voltage drop when connecting IKS01A2 to B-L072Z-LRWAN1

Posted on April 03, 2018 at 18:10So the B-L072Z-LRWAN1 board is configured to be powered through the 3.3V pin by removing SB6 and R26. Furthermore, the ST-LINK was disconnected by removing SB28, SB29 and SB37. When testing with some example code and...
