How can I use two sensors over the same I2C1 line at the same time?

Hello everyone, I have recently started learning C language and I am kind of new into embedded systems. I am using NUCLEO WB15CC and trying to develop a system using VL53L1X with MPU6050 sensors. I am getting two sensor data successfully every time I...

Using STM32WB55 BLE Heartrate example as start point then adding I2C functionality to read sensor but second I2C exchange (e.g. read) causes code to hang in HW_TS_RTC_Wakeup_Handler().

Working on project with BLE interface and need to add I2C interface to read a sensor. Started with BLE Heartrate example (it wakes up ever 1s which I also need to do) and added I2C by using CubeMX to generate the new code. To start testing I added th...

Reading I2C sensor data over bluetooth on mobile applications.

Hello, I have recently started coding and learning C language. I implemented VL53L1X drivers to my NUCLEO-WB15CC and I am able to get measurements over USART communication. However, I would like to get these measurement results over Bluetooth and I w...

radio init planting

Hello, I'm using a STM32WL55JC in dual core configuration to communicate with LoRa protocol.I'm also working on an OLED display interface using I2C communication on the same MCU.I have a working application using LoRa communication without OLED inter...

I2C configuration in STM32WL

Hello, I'm trying to connect an OLED display to my STM32WL55JC by I2C but it doesn't work...I've successfully connect it with a STM32F411RE but the I2C configuration / HAL interface seams to be different between both MCU...Here my config on the STM32...

STM32: consumption due to I2C in stop2 mode

Hi, I use the nucleoWL (STM32WL which is based on STM32L4). I want to use LPWAN to communicate some measurements each day. I use I2C between MCU and sensors. If I try the Sigfox Push Button exemple, I have 2uA in stop2 mode but if I add I2C1 (thanks ...

HAL_I2C hangs when it enters I2C_WaitOnFlagUntilTimeout() function.

I'm using verion 1.1.5 of the I-CUBE-LRWAN software and reading a few I2C sensors using the HAL_I2C functions. No issues when sensors are functioning properly; however, I have run into periodic sensor failure issues while testing, either permanent or...

I've a problem with the integration of I2C communication within the Sequencer utility.

I'm working with STM32WL (Nucleo board). I connect it to a sensor via I2C and everything goes fine until I try to call the communication function via Sequencer. Using the Sequencer I get an error from HAL_I2C_Master_Transmit. The error is a timeout f...

How to add I2C to I-CUBE-LRWAN SDK SubGHz_Phy example? The reason I'm looking for it is that I was able to run SubGHz_Phy successfully but I'm unable to add the I2C to run successfully.

It's very hard to add it without instructions to not break existing infrastructure with LoRa.When I run simple example generated from classic .IOC file I got the I2C running without a problem.The board I'm using: Murata Type 1SJ

Sending a Zigbee message from board to board triggered by I2C Temperature Sensor

I am currently using 2 STM32WB55RG MCUs (one as a server and one as a client) with a Si7021-A20 temperature sensor that is completely functional on the "client" MCU and have no idea how to trigger a signal to be sent to the server from the client to ...
