Once this SPI transaction is submitted to SPI driver on ESP peripheral, Handshake pin is pulled high to indicate host that ESP peripheral is ready for transaction. 一旦spi传输提交到了驱动层,handshake引脚会被拉高。 In case if TX buffer has valid data, Data ready pin is also pulled high by ...
These devices where using UART to communicate with computers. Although these clunky cables have been replaced with USB, you can still find UARTs being used in DIY electronics such as Raspberry Pi, Arduino, and other common microcontrollers. We can use it to connect Bluetooth modules and GPS ...
