To add ESP8266 Support to Arduino IDE

https://randomnerdtutorials.com/how-to-install-esp8266-board-arduino-ide/

You also need: From Boards Manager:

**CRITICAL: USE VERSION 2.4.0 FOR NOW. **Later versions have bugs in the toolchain which prevent working binaries.

This is the NodeMCU 1.0 board we are using:

Longruner 2pcs WiFi Internet ESP8266 Module CP2102 ESP12E NodeMCU LUA Development BoardWi-Fi Wireless Micro Controller with GPIO pins Compatible with ArduinoIDE LKY69

Available from Amazon: https://www.amazon.com/gp/product/B06X8ZJG87

If your Arduino environment gets wonky:

• Delete your Arduino directory

• Reinstall board support

• Re-install libraries needed.

Location of Arduino project directory:

• Windows: Documents\Arduino

• Linux: ~/arduino

• Mac: ~/arduino

• Open atariwifi.ino in Arduino IDE [https://gist.github.com/mozzwald/f84692d942111a29a6764c2f45a35152]

• Remove NodeMCU board from test board, if needed.

• Plug in NodeMCU board, check for teal LED

• Set board settings as above, ensure COM port is set correctly to your board.

• In Arduino IDE press the Upload toolbar button.

• Resize the status area below if needed to see the output from the compiler and the programming tool.

• The blue LED on the NodeMCU should start flashing, indicate receipt of flash data.

• You should also see an indication that the device is being flashed, an example of a successful flash, is below:

We are currently setting aside one megabyte of space in the 4 megabyte flash RAM to hold data files for different purposes. For now, this is all treated as a SPIFFS file-system. You can replace the data on the SPIFFS file system, without needing to re-flash the firmware, but you do need to flash the SPIFFS area, at least once.

• If you haven’t installed the ESP8266 Sketch Data Upload tool, please do so, you can grab it here: https://github.com/esp8266/arduino-esp8266fs-plugin and follow the instructions to install into your $ARDUINO/tools folder.

• Currently, we use one file, ‘autorun.atr’ which lives in the data/ directory. This is an ATR formatted, single density disk. (yes, it’s ATR now)

• If replacing, please place any contents you want on the filesystem into data/ This is currently ATR images, but may be other things as we develop things out.

• Select ESP8266 Sketch Data Upload

• If working correctly, you’ll see a list of files being pushed to the SPIFFS, and their address locations, followed by a status display of flashing. It copies an entire 1 megabyte image to the SPIFFS, so this takes a few minutes

• Improving SIO timings, I suspect they are marginal

• Implementing a TNFS client for network filesystem, based on protocol specification here: http://spectrum.alioth.net/svn/filedetails.php?repname=Spectranet&path=%2Ftrunk%2Ftnfs%2Ftnfs-protocol.txt&fbclid=IwAR1Ufed88zCmVzch5Kqo3ccM7GYpDJaZHnX30g9LKWNL9lV5zD2GaU3iaO4 It runs over UDP, so should be trivial to implement.

• NAT-UPnP port forwarding for UDP for TNFS service

• How to properly handle UDP traffic in Arduino. Argh.

This is a list of the Proposed SIO commands for given device classes.

Device	Command	Aux1	Aux2	Description
$70	$00	$00	$00	Reset Adapter
$70	‘!’	$00	$00	Get Network Information
$70	‘M’	DD*	DM*	Mount Disk Data is /disk_image.atr
$70	‘U’	DD*	00	Unmount (umount) disk
$70	‘&’	$HT	$00	Send back handler
$7n	‘O’	$CT	$00	Open network connection Data is :PORT#
$7n	‘C’	$CT	$00	Close network connection
$7n	‘R’	$00	$00	Read bytes from connection
$7n	‘P’	$00	$00	Put bytes from connection
$7n	‘S’	$00	$00	Anything waiting? (STATUS)

• DD is Disk device # (aka $31 for D1:)

• DM is Disk Mode (D0 = Read, D1 = Write)

• HT is handler type (D0 = RS232, D1 = Network)

• X is 1-8, allowing 8 max connections.

• CT = (1 = TCP, 2 = UDP)

• https://docs.google.com/spreadsheets/d/1qEPPM3-gqzfHsogJYuVXqhbvSSsgxdQMb_KGfpoV9KI/edit#gid=0 (the pins used by AtariWiFi)
