Application must assure, DMA and UART interrupts utilize same preemption priority level. This is the only configuration to guarantee processing function never gets preempted by itself (DMA interrupt to preempty UART, or opposite), otherwise last-known read position may get corrupted and application w...

示波器破解CAN错误帧/BusOff的经验分享 MCU内置了CAN控制器用来将MCU的数据封装为CAN帧格式,同时它也负责CAN帧的校验和错误帧的处理。控制器封装好的逻辑报文经TX RX送到CAN收发器,将逻辑信号转变为真正的总线差分波形。 2023-09-08 09:19:32 请问STM32L432 UART帧错误是什么? 一个奇怪的问题,使用STM32L432...
Pinout & Configuration 页面,Connectivity栏中设置SPI屏幕接口,I2C触摸接口,外部存储器的QSPI接口,UART调试端口,WiFi模组的通信口(UART)。首先是屏幕的SPI接口,设置全双工主机,按住ctrl,光标移动到PA1端口,点击左键拖拽SPI1_SCK至PA5,并将PA6/PA7右键Signal Pinning进行端口锁定。
