Dear ST Community Support,We are currently evaluating the ST4SIM-200M eSIM module for integration into our IoT devices and would like to clarify some details regarding its activation and compatibility.Specifically, we would like to confirm whether th...
When looking at the datasheet for the ST67W611M1, it seems that pins CHIP_EN, SPI_CS, and SPI_RDY are all High active. Is this really correct, or are some signals simply missing the bar on top? Also, the description for pin BOOT doesn't indicate whi...
Hi Team, Do you support USB type C PD 3.1 supporting 240W for sink applicat? If yes, please suggest a suitable part number with the datasheet. If you do not support 240W, please let us know the maximum power supported by STM for USBPD 3.1 application...
Hello everyone.I'm currently building a controller for this energy measurement chip.So far, I've built my controller and can perform a remote reset and read data, but when I want to configure a register, I send my desired configuration, but when I re...
Hello, I am using STPM34 smart metering chip to read 230 VAC voltages and currents. I am using 3 chips on 1 board:First 2 STPM34 measure 3 phases of 230 VAC voltages and currents, 3 STPM34 measures 16 multiplexed current channels and no voltage.I am ...
Hello,Could you please provide a simple example source code to operate an S2-LP transceiver under the following conditions? My MCU is an STM32F103 connected via SPI1.A 25 MHz crystal is fitted to the S2-LP.External SMPS (1.8 V) is used.I want to tran...
Hello everyone, I’m trying to control an S2-LP QTR via SPI1 on an STM32F103VCT. I completed the initial setup and configured the radio to 420 MHz. I then wrote a routine to transmit periodically, but I’m not seeing any RF output on the antenn...
Hello,I'm trying to make a low power device with ST BlueNRG-LP (455M). I have an incomprehensible error with the BLE.I set BLE advertising with advertising data and scan response every 10 seconds (adv_interval=10000). ret = aci_gap_set_advertising_c...
我的 L9663 SPI 无法正常工作，我想通过寄存器读取L9663的设备ID，但接收回来都是0XFFFF。我现在使用的MCU是STM32F103C8T6,以下是我的计划，希望大佬们帮我看一下有没有问题。
I'm experiencing a problem with the ST IO-Link Sensorkit and Master (STEVAL-IDP003V1/STEVAL-IDP004V2). I've connected the Master device via USB and used the TEConcept Control Tool as described in the ST instructions. Everything went smoothly up to st...
