arduino esp8266 development board

Overview

For the esp8266 development board, it is recommended to go to csdn to read the tutorial by the rookie brother. I personally think it is the best tutorial currently developed for esp8266arduino. Resistors R3 and R4 play the role of voltage divider. Because the maximum adc of 8266 is 1v, it needs to be divided when connected to 3.3. You can leave r7 unconnected, or connect it to a capacitor filter, or you can consider shorting it directly, but remember that the maximum input voltage is 1v. You don’t need to weld the unused parts of the switching power supply (that is, the parts I did not weld)

Implementation of a similar image player
I want to implement a function similar to a picture player in WinCE. It is equivalent to being able to pause and stop the picture during playback. My idea is to call a while loop after entering the pi
msp430 contains ADC12 module program implementation
The program mainly implements a relatively general initialization procedure, the content is as follows: char ADC12Init(char n,char channels[],char rep) { if(n>15) return 0; //SHT0_0 ADC12CTL0 = ADC12O
CH554 Review: 4.ADC Test
First of all, I would like to thank the administrator. Because the CH554 board I got before had problems during the test and the computer could not recognize it, the administrator mailed me a new boar
