(System on Chip). It has the capacity to integrate Wi-Fi functionality into systems or run as a standalone application. It is a low-cost option for IoT application development. TheESP-12Eis part of the ESP-XX series. ESP8266 SoC is used in all of them, although they differ in terms...
When GPIO0 is pulled LOW, it sets the ESP8266 into bootloader mode. This is the same as pressing the on-board FLASH/BOOT button. GPIO16 GPIO16 can be used to wake up the ESP8266 from deep sleep. To wake up the ESP8266 from deep sleep, GPIO16 should be connected to the RST pin....
The ESP32 has 18 x 12 bits ADC input channels (while the ESP8266 only has 1x 10 bits ADC). These are the GPIOs that can be used as ADC and respective channels: ADC1_CH0 (GPIO 36) ADC1_CH1 (GPIO 37) ADC1_CH2 (GPIO 38) ADC1_CH3 (GPIO 39) ADC1_CH4 (GPIO 32) ADC1_CH...
I2Cwrapper is a firmware framework which helps you implement Arduino based I2C target (slave) devices for control of non-I2C hardware. Supports plain Arduinos, ESP8266, ESP32, SAMD, STM32, and ATtiny platforms. - ftjuh/I2Cwrapper
blynk - Platform with iOs and Android apps to control Arduino, ESP8266, Raspberry Pi and similar microcontroller boards over the Internet. (Source Code) AGPL-3.0 Java CUPS - The Common Unix Print System uses Internet Printing Protocol (IPP) to support printing to local and network printers. (...
GPIO1: pin is high at BOOT, boot failure if pulled LOW GPIO10: pin is high at BOOT GPIO9: pin is high at BOOT Pins HIGH at Boot There are certain pins that output a 3.3V signal when the ESP8266 boots. This may be problematic if you have relays or other peripherals connected to ...
