Hello All,I have recently started using STM32 mcu and quite new to it. I am developing a project in which 3-phase energy meter is needed which measures voltage, current and power of 3-phase AC signal for which MCP3903 IC is used, as I came to know th...
Hi.Chip: ST BlueNRG-345ACPCB: Custom board with VLXSD pin left floating and VFBSD pin ->3.3V, NX2520SA 32MHz, schematic mimics STEVAL-IDB011V1, just bare chip without MEMS or CMSIS_DAP debugger, just MCU, decoupling capacitors, chip-antenna with matc...
Hello, I'm a student engineer and I'm working on a project which aim is to retrieve environmental data such as Temperature, Humidity and luminosity... and to send them via Bluetooth to my phone. I'm using STM32F401RE board + X- NUCLEO- IDB05A1 and co...
Which is the state between two advertising events for the calculation of the battery lifetime?Shutdown or Deepstop?Is the current profile shown in the plot obtained when exiting shutdown or deepstop state?Thanks
https://community.st.com/s/question/0D53W00000TFnQJSA1/unable-to-debug-or-program-stevalidb008v1m-using-stlinkv2The question in the link above is exactly similar to mine, but instead I am using a ST-LinkV3 debugger instead of their V2. I figured I wo...
Dear Sir/Madam, This mail is regarding to know the status(lifecycle) of the component. We wanted to know the part status of these components like whether it is active or obsolete,and wanted to know whether it is RoHS complaint ,if in cas...
Hello everyone,I have in my possession a X-NUCLEO-BNRG2A1, in order to get familiar with BlueNRG-M2SP. After using and tweaking STM32 samples, I can use the BlueNRG-M2SP (through the expansion board) effectively. However, I saw that you can download ...
Hello everyone,I have in my possession a X-NUCLEO-BNRG2A1, in order to get familiar with BlueNRG_M2SP. At BlueNRG_M2 datasheet, on page 12, there are described for different "modes", where the functions of module pins are changed depending on the ...
