Hello Everyone, For a project, I'm using a NUCLEO-L432KC board and it is connected to external sensors, Tx, and Rx (which work with 4-5 V). I want to use an X-Nucleo-LPM01A to measure its power consumption. Based on the NUCLEO-L432KC documents, I hav...

In my application, I receive a message from LoRa and intend to transmit it via UART1 which is set to PA9 and PA10. However, when I check the UART RX using a logic analyzer, I do not receive anything.I have tested the UART1 alone in a simple project, ...

Hello @Andrew Neil @RomainR. I want to thank you both for your help and support. It appeared that the problem was the AREF. It was provided by the X-Nucleo-LPM01A, and I was able to measure it on the pin.However, I discovered that internally, the AR...

Yes, your diagram is correct. LoRa, Sensor, and Optical TX are connected to +3v3 and +5V pinsSTM32 also is supplied from X-Nucleo-LPM01A using AREF pinAll three power sources are available for the system (I have checked the pins using a multimeter). ...

Thanks Andrew. I have provided a photo below that shows all the connections.Reds are the power lines and blues are the signal lines. Also, I have to mention that I tested the system. when JP1 was not connected signal lines did not work (I checked wit...

Dear @RomainR. @Andrew Neil Thank you for your help and time. I understand your points. What I gather from what you're saying is that even when JP1 is open, it will not affect other peripherals. However, I believe it does affect them.In UM1956 Rev 5...

Dear @RomainR. Simply I can say that the application continuously measures CO2 and tVOC every second using a sensor connected to the board via I2C1. This sensor is powered by the 3.3V pin.The gathered sensor data is then transmitted using two differ...

Using X-Nucleo-LPM01A for measuring power consumption of NUCLEO-L432KC

Hello everyone, I am encountering an issue with UART1 while using STM32WL for LoRa Communication with SubGHz_Phy_Per and STM32WL-SubGHz-PhyBasic-Tx-Rx examples from the STM32 Github.
