3.1、USB协议 通用串行总线(Universal Serial Bus,简称USB)是1994年提出的一种支持热插拔的外部传输总线,现在不管是在什么设备上都可以非常容易看到它,USB协议从诞生到如今经历了很多次升级换代,如下图所示为USB历史版本号及传输速度等相关信息(注释1) 另外在USB2.0的基础上还扩展出了一种既可以工作为USB主机又可
The general call addresse for all devices on the I2C bus is 0. This address can be used by the master to communicate with all the slave devices on the bus. It’s up to the slave device whether to acknowledge this address or not....
SDIO Clock divider bypass(时钟分频器旁路使能):使能该参数时,SDIO_CLK=SDIOCLK;否则SDIO_CLK频率由时钟分频因子决定 SDIO Clock output enable when the bus is idle(空闲模式时钟输出使能):节能模式,此实验不使能 SDIO hardware flow control(硬件流控):设置是否使能SDIO的硬件流控,此处不使能 SDIOCLK clock divid...
DMA is generally used when we need to receive a large amount of data. The DMA bus is a separate unit and hence the data transfer does not utilize the CPU. Instead the CPU can be used to handle the other tasks. ADVERTISEMENTIn today’s tutorial, we will use the DMA in normal mode ...
Cheers, Valentine 1 Like runger September 21, 2022, 2:57pm 9 TBH, I’d say if you’re ready for CAN-bus, you’re ready to move on from ArduinoIDE. All its advantages when you’re new to programming really become disadvantages once you have a bit of experience…Home...
You can also quickly check how consistent is the transfer speed over time by adding a scalar real-time watch: intg_BytesTransferred;ScalarRealTimeWatch g_BytesTransferredWatch;intmain(void){//...constintbufferSize=4096;charbuffer1[bufferSize], buffer2[bufferSize];for(intiter=0;;iter++){inttot...

I2C 通讯协议 (Inter - Integrated Circuit) 是由 Phiilps 公司开发的,由于它引脚少,硬件实现简单,可扩展性强,不需要 USART、CAN 等通讯协议的外部收发设备,现在被广泛地使用在系统内多个集成电路 (IC) 间的通讯。 在计算机科学里,大部分复杂的问题都可以通过分层来简化。如芯片被分为内核层和片上外设; STM32...
