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...
Hi, please see attached screenshot. 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 instruct...
Dear Manager.Hello, I am a student studying at a Korean university.I am developing a two-channel small ultrasound system.1. Try to use STHV748, a 4-channel pulser, as a pulsar, and don't use the other 2 channels. Should I connect to GND for channels ...
Hi to everybody and thank you in advance. I'm planning tu use the STISO620 as a function replacement for old-school optocouplers. STISO620 matches in every metric. My plan is use the part to interface an STM32 MCU.My application will detect falling e...
hi all, i want to configure the L9963e Bms Ic from externel mcu and i need to implement the communication to the BMS so that i can read read and write the register values i.e, vcells values etc .Thank you
