Hi ST Community,Are the NC pins completely isolated from the device. Wishing to know if there would be a problem with them being driven, pulled to VCC or to VSS. Thanks!

Just joined the community! I'm pretty new to electronics and am still learning the ropes. I'm currently tinkering with a small project involving LEDs and resistors.I'm really excited to learn from all of you and hopefully contribute more as I gain experience. Any tips for a newbie just starting out in the world of electronic components? What are some good resources or topics I should focus on early on?Looking forward to being part of this community!

Hello All, I am currently working on a project where we are using the ST33HTPH2032AHD1 TPM. This TPM is connected to our System on Chip (SoC) via the SPI interface. As I am relatively new to TPMs, I am seeking assistance in testing the TPM functionality from the SoC using SPI. Specifically, I am looking to do this using a standalone application. Here are some details about my setup: TPM Model: ST33HTPH2032AHD1 Connection: SPI Interface I would greatly appreciate it if anyone could provide guidance or share any relevant resources that could assist me in this process. Any sample code, documentation, or step-by-step guides would be extremely helpful. Thank you in advance for your time and support.

STEVAL-FCU001V2 is the new version. But I cannot find the code of STEVAL-FCU001V2 on github. Is STEVAL-FCU001V1 code on github compatible with STEVAL-FCU001V2? Thank you very much   STEVAL-FCU001V1 code: https://github.com/STMicroelectronics-CentralLabs/ST_Drone_FCU_F401/tree/master    

I have a black pill, but board is green in color, chip says stm32f401ccu6, 44pin.where can i get a pinout diagram for this board, ?only blackpill boards pinouts that I can see are the newer 40 pin boards

Hi,I have been trying to design a double stage single phase grid connected PV Microinverter system.I came across an Application Note AN4070, in which you have designed a 250W grid connected Microinverter. I tried to follow the procedure and design and simulate a system in MATLAB, but my system is not working properly. I have designed the MPPT Block, and it works just fine. I believe the problem lies in the Inverter stage. I have few questions and would really appreciate any help or guidance from your side.1. While looking at Current Control Algorithm, I realized that the alpha and beta components taken for Grid Voltage (Fig. 20) and Current (Fig. 21) are opposite to each other. Can you please help me understand why they are measured in such a way or maybe point me towards a resource that can help me understand the theory behind it.2. I would also like some help in designing the PID blocks for the Current Control Loop. I understand the concept, but I am unable to imp

Hello,I'm working on a project that requires the implementation of NB-IoT and to do this I started by testing the Discovery Kit B-L462CELL1, which is very poorly documented. I also noticed that the LBADXX1SC modem used by the kit is now obsolete.Can you recommend a development board from ST Microelectronics that would enable me to do NB-IoT (with zephyr would be a plus)?Thanks in advance.

 Hello.I want to use STUW81300 to create 9 GHz with great phase noise.Reference: 50 MHzPDF:50MHzSingle-EndedSTWPLSim v5.3 was used for the loop filter design.However, the actual measurements were 3~7dB worse than the simulated values.All settings seem to have been completed without any issues.I would like to ask for advice if this difference is normal or if there is something wrong with the design.Simulation:-81dBm/Hz@100Hz offset-94dBm/Hz@1KHz offset-102 dBm/Hz@10KHz offset-106dBm/Hz@100KHz offset-124dBm/Hz@1MHz offsetMeasurement:-77dBm/Hz@100Hz offset-88dBm/Hz@1KHz offset-95dBm/Hz@10KHz offset-103D Bm/Hz@100KHz offset-120dBm/Hz@1MHz offset

Both STuW81300 and STW81200 have the option of using an external VCO but the inputs characteristics aren't specified anywhere. What is the input frequency range, input power/sensitivity in dBm or 50ohm match for single-ended input? There is one application diagram showing VCO output with a coupling capacitor followed by a balun. Can we just ac ground the other pin instead of a balun?

Hello,According to data sheet on STuW81300 the ST1.PLL_SEL must be 1 and Nint, Frac must be calculated based on formula on page 25, when VCO frequency if higher than 6GHz. In this case the sub-harmonic at half frequency appears. How could be this sub-harmonic eliminated or reduced significantly?Thanks,Alex

Hello,When the ST1.PLL_SEL is set to 1 for VCO Frequency > 6 GHz, the sub-harmonic at half frequency appears. How could it be eliminated? Thanks,Alex

Can anyone help identify this chip, please!Thanks in advance!!

Dear forumI need to update a board that uses BMO055 9 axis IMU and I need to know what is the preferred ST solution that best fit this obsoleted part.I need the 3 axis gyro + 3axis accelerometer + 3 axis magnetometerIf there is a single chip solution its okay, but a dual chip solution can work as well. Thanks in advanceIgnacio

I am looking for RoHS, REACH and Proposition 65 certificate for part the parts below, someone please provide it or let me know from where or how I get it. STPSC20G12WL STW3N170

We use M41ST87W as RTC module. We set the stop bit (ST) to 0. We can also observe the frequency at the F32K output. We constantly read the Second register but we do not see any change. What could be the reason for this?

I purchase one M5STAck COREMP135, it noticed work for linux, but when I use the software, it can't handle user account , only use root login.Then I try build image by myself, the github support was 2-3 years ago.I see one training company - Bootlin support STM 135 , but they didn't support COREMP135.Compare with Beaglebone black, the M5STACK-COREMP135 is too bad in software side. 

hello, i would require a specs sheet for the following IC. i cannot find any information online. if its not visable from the picture it has a DIP20 package. Thank you

I designed hardware by myself and used MCSDK 6.3.2. I chose HSO algorithm in Workbench, this work well except flux weakening feature is missing. So we cannot run motor with full load. Please advise how we can config Workbench to use HSO together with Flux weakening.

Best SPI Routing Method for Double-Sided 16×128 LED Matrix Using STP24DP05Project OverviewI am designing a double-sided 16×128 RGB LED matrix display using STP24DP05 LED drivers. The LED drivers are controlled using a single SPI bus from the MCU. Since the display consists of both a front and back panel, each panel consist of 16 STP24DP05 LED driver. I am considering two different approaches for routing the SPI and error signals and would like recommendations on the best solution.Approach 1: Split SPI and Error Signals Using BuffersIn this approach, I use buffer ICs (74LV244) to split the SPI bus and drive both the front and back panels independently. Additionally, the error signal (ERR) from the STP24DP05 drivers is also split and handled separately for each panel. Each panel consist with 16 LED driver. SPI Control: The SCK, MOSI, MOSI and CS signals are buffered separately for the front and back panels.MCU Control: The MCU enables/disables the SPI buffers using GPIOs, ensuring t

I am trying to switch between modes (standby, rx, tx, sleep) in the sx1262 module. While switching, I pay attention to the figure below in the datasheet of the lora module. For example, to switch from SX126X_STANDBY_CFG_RC mode to RX mode, I use the command sx126x_set_rx(&myLoRa, 0). Then I use the command sx126x_get_status(&myLoRa, &radio_status) to check if the module has switched to rx mode but the cmd_status value is read as "SX126X_CMD_STATUS_CMD_EXEC_FAILURE" and the chip_mode value is read as "standby".
