ST8500+STLD1直流载波
您好！目前我有几个STM8500+STLD1直流载波通信的疑问，请麻烦回复！1：我通过STLD1发送差分信号，通过高压电容耦合在DC48V和DC48V_GND上，再在接收端进行接收，应该没啥问题吧，理论传输距离可以达到3km吧，有没有完整一些的参考原理图设计，因为官网提供的手册原理图不完整2：stm32f401通过uart与st8500进行通信，调用at指令或者api接口就能使用st8500吗，还是我需要在st8500上面进行编程或者要下载固件才能使用

ST67W61 SPI communication for AT command protocol
Hello, I write this post because I have a question while using the ST67W61 chip. First,I tested soft-AP function with a NUCLEO-H563ZI board and an X-NUCLEO-67W61M1 board.I used sdk example project ST67W6X_CLI of x-cube-st67w61-v1.0.0.It worked well....
Trying to run SensorDemoBLE on STM32H723ZG using BlueNRG-M0A on the X-Nucleo-IDB05A2
As the title says, I'm trying to just simply run the SensorDemoBLE project. My configurations should be correct, my spi data size is set to 8 bits, and a clock baud rate of 6.0 Mbit/s. First of, after generating the project there's loads of errors wh...
ST67W611M1 UART Bootloader handshake fail (Error 0050 in QConn_Flash)
Hello, I’m trying to flash the ST67W611 Wi-Fi module directly through UART, without using the NUCLEO host board.For hardware setup, I soldered simple tactile switches and 0.1 µF capacitors on the CHIP_EN and BOOT pins.When powering up:I press both sw...

ST67W611M1A6BTR NCP Firmware Flashing: “SHAKEHAND FAIL” with QConn_Flash
Hi all,I’m working with a new ST67W611M1A6BTR Wi-Fi module on a customized STM32H745 board.I followed the official X-NUCLEO-67W61M1 and NUCLEO-U575ZI-Q passthrough example, and I am able to communicate with the module (UART passthrough to PC works, a...
How to generate the wake-up request pulse (WURQ) with an L6360?
I simply can't figure out how to generate this pulse with my STEVAL-IOM001V1 board. Even the supplied code (en.stsw-iom001) doesn't make me any wiser.
