- connecting the int/enable pins of the pcf8574 to the esp12
- adding switch/button and reset circuit
- connecting free pins of esp12 to free pins on the header
- TESTING the hardware with #Ignore this ESP8266 board
- write some sweet code, libs and configs for Arduino IDE
- add an LED for blinking stuff
ESP8266 board with classic Arduino footprint
trying to match the classic Arduino footprint with an ESP-12E/F, PCF8574 port expander and a 4051 as an analog demultiplexer - for fun
I found a TFT shield for the Arduino and was wondering about how much it would take to get the ESP12 accept most of the shields that are out there. Not sure how much effort I'm going to put into this, but I wanted to share it and hear some thoughts from you guys. There is definitely some effort to be made in software, but this is kind of interesting to me too. I want to know how to add boards to the Arduino IDE the right way, configure pins and change common functions to work with this board. I still have to add the stuff I've put on my ESP dev board. Some connections won't make sense yet, I'm especially worried about the I2C being on the same chip as an IO, that controls itself, but it might work with the int/enable pin on the PDF8574.
