Here is the result of the transmission of 4 bytes using a succession or checking TxBuffer flag, sending with WriteBlocking, checking RxBufferFull and reading with ReadData, Channel one is MISO and channel two is SCLK. EDIT : I am having the same signals whether the flash is connected or ...
如果我使用 SPI_WriteArrayBlocking 或 SPI_WriteArray,則會發生與上面相同的結果。 如果我嘗試使用 SPI_transfer,如下所示: voidTestSPI(uint8_t data){cy_en_scb_spi_status_t errorStatus;uint8_t txBuffer[1];txBuffer[0]=data;/* Initiate SPI Master write and read transaction. */errorStatus=SPI...

NIO (Non-Blocking IO) Selector 一般称 为选择器 ,也可以翻译为 多路复用器, Connect(连接就绪)、Accept(接受就绪)、Read(读就绪)、Write(写就绪) Netty基本原理: 7.3、dubbo原理 1、dubbo原理 -框架设计 config 配置层:对外配置接口,以 ServiceConfig, ReferenceConfig 为中心,可以直接初始化配置类,也可以通过...
