SPI(Serial Peripheral Interface)是串行外设接口的缩写,是一种高速的,全双工,同步的通信总线,并且在芯片的管脚上只占用四根线,这四根线分别是: MISO– Master Input Slave Output**,**主设备数据输入,从设备数据输出,也称SDO。 MOSI– Master Output Slave Input,主设备数据输出,从设备数据输入,也称SDI。 SCLK...
This is a output pin for ESP peripheral. This pin is used to indicate host that the ESP peripheral wants to send a data packet to it. This pin stays high till the host reads this data packet. Reset/EN pin This is a input pin for ESP peripheral. This pin resets ESP peripheral and i...

As you can see abovePCF8574has 4 input pinsGND, VCC, SDA, SCLand 16 output pins. We will connect our LCD1602 to these 16 output pins. What is the ADDRESS for PCF8574 The General Address Pattern for this Device is0100xxxin 7 bit Address system. ...
input pins only. They cannot be configured as digital output pins. Also, unlike other GPIO pins, these pins do not have internally connected push-pull resistors. Therefore, when using any one of these pins as a digital input pin, we need to connect an external pull-up or pull-down ...
It also contains input and output shift registers. Transmitting and receiving control. A read or write control logic. Other optional components of a UART are: transmit or receive buffers, FIFO buffer memory, and a DMA controller. UART technology ...
