Interfaces 

 

                                                  Table 3    Descriptions of Interfaces 

Interface                               

Pin Name 

Description 

HSPI 

IO12(MISO), 

IO13(MOSI) 

IO14(CLK), 

IO15(CS) 

SPI Flash , display screen, and MCU can be connected using HSPI 

interface 

PWM 

IO12(R), 

IO15(G), 

IO13(B) 

Currently the PWM interface has four channels, but users can extend 

the channels according to their own needs. PWM interface can be 

used to control LED lights, buzzers, relays, electronic machines, and 

so on. 

IR Remote 

Control 

IO14(IR_T), 

IO5(IR_R) 

The functionality of Infrared remote control interface can be 

implemented via software programming. NEC coding, modulation, 

and demodulation are used by this interface. The frequency of 

modulated carrier signal is 38KHz. 

ADC 

TOUT 

ESP8266EX integrates a 10-bit analog ADC. It can be used to test the 

power  supply  voltage  of  VDD3P3  (Pin3  and  Pin4)  and  the  input 

power voltage of TOUT (Pin 6). However, these two functions cannot 

be  used  simultaneously.  This  interface  is  typically  used  in  sensor
