默认初始化选用 4M MSBFIRST SPI_MODE0 其他初始化方式 setup()函数中调用SPI.begin()初始化SPI接口。此处为默认设置。若要设置具体参数可使用如下语句初始化SPI. 1SPI.beginTransaction(SPISettings(14000000, MSBFIRST, SPI_MODE0)); SPISettings()函数设置SPI传输模式,SPI.beginTransaction()函数根据SPISettings()...

with an MSB first SPI master, use the following sequence to send the bytes. spi_send(S3); spi_send(S2); spi_send(S1);
SPI协议 摩尔斯电码 高位先行(Most Significant Bit first) 高位先行(MSB先行)是指在数据传输过程中,数据的最高有效位(Most Significant Bit,即数值最大的那一位)首先被发送。这种设计在许多串行通信协议中被采用。 高位先行的优势 提前了解数据大小:在处理大量数据时,接收方可以更早地知道传输的数据的大致大小,...

To diagnose the error, first enable a diagnostic log (use the-verbosity:diagcommand-line switch), and check the MSBuild log file with the full diagnostics output. For bigger output logs on large projects, consider using the binary log (-blcommand-line switch) and theMSBuild Structured Log ...
