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。
Hi,I would like the DC/DC converter of STKNX to make 5V.Also, I want the Linear regulator to make 3.3VBecause of global efficiency, I wanted to power the linear regulator with the 5V output of DC/DC converter.I'm surprised that the datasheet specifie...
Hello there :)I'm trying to use a KSZ8863 Ethernet PHY with the STM32F767. I'm using the Nucleo F767ZI Board where i unsoldered the jumpers to the onbord PHY. The KSZ8863 is then connected via the Morpho connectors.I just used the Code generated by t...
Hello,I hope you are well.I am using your bluetooth modules with chip antenna “BLUENRG-M2SA” and PCB antenna “BLUENRG-M2SP”.I'm going to put the 2 modules in the potting ? is there an influence of potting on the characteristics (range, transmission, ...
Hi community,I have purchased the STEVAL-IDP004V2 master evaluation board and STEVAL-IDP003V1 ( with STEVAL-IDP003V1T temperature sensor ).I connected the STEVAL-IDP004V2 and the STEVAL-IDP003V1 and the USB cable (Not RS485) on my PC.I downloaded the...
