I have a problem with an ESP32 devkit V1 card. I'm trying to connect a WG12864A Winstar mod graphics display via the I2C MCP23017 adapter (RobotDyn), using Nick Gammon's I2C_graphical_LCD_display.h library. Everything works well by connecting it to the Arduino Uno - Duemilanove board. Adding an MCP23017 I/O Extender to Arduino or ESP8266: UPDATE Okt 2017: Although this works flawlessly, I would now advise against making it for the simple reason that a cheap, ready made module is available on aliexpress, the price of which rivals the price of the DIL chip alone.I am not claiming th...

Sep 30, 2017 · The objective of this post is to explain how to handle external interrupts using the ESP32 and the Arduino core. The tests were performed on a DFRobot’s ESP-WROOM-32 device integrated in a ESP32 FireBeetle board. Introduction The objective of this post is to explain how to handle external interrupts using the ESP32 and the Arduino core. the MCP23017. The operation is ended with a Stop (P) or Restart (SR) condition being generated by the master. Data is written to the MCP23017 after every byte trans-fer. If a Stop or Restart condition is generated during a data transfer, the data will not be written to the MCP23017. Both “byte writes” and “sequential writes” are sup- Oct 18, 2015 · How to create a 3D Terrain with Google Maps and height maps in Photoshop - 3D Map Generator Terrain - Duration: 20:32.

May 10, 2018 · Interfacing an ESP32 to an MCP23017 GPIO expander. While the ESP32 sports a number of GPIO pins, not all are broken out on every board, meaning that sometimes a GPIO expander is necessary. This project is a simple design to test interfacing the ESP32 to an MCP23017 via the I2C interface.
