Prerequisites

This guide assumes you have a 4MB ESP12F microcontroller and use Arduino IDE.

• Board Manager: You will need to add the support for this board to your IDE (Arduino in this case), see: https://github.com/esp8266/Arduino
• SPIFFS: You will need to add SPIFFS file upload support to Arduino if you want to upload files to the ESP12F, see: https://github.com/esp8266/arduino-esp8266fs-plugin

Uploading Code

For ESP12F use the following settings in Arduino IDE

• Board: Generic ESP8266 Module
• Builtin Led: 2
• Upload Speed: 921600
• CPU Frequency: 80 MHz
• Crystal Frequency: 26MHz
• Flash Size: 4MB (FS:3MB OTA: ~512KB)
• Flash Mode: DOUT
• Flash Frequency: 40MHz
• Reset Method: dtr (aka nodemcu)
• Debug port: Disabled
• Debug Level: none
• LwIP Variant: v2 Lower Memory
• VTables: Flash
• Exceptions: Legacy (new can return nullptr)
• Erase Flash: depends on if you want to change SSID, Files, or only Sketch
• Espressif FW: nonos-sdk 2.2.1+100 (190703)
• SSL Support: All SSL ciphers (most compatible)
• Port: depend if u are uploading Over The Air, or using a cable
• Programmer: AVRISP mkII

These settings give you about 2.471 KB of SPIFFS storage space for files and ~512KB sketch size

Over The Air (OTA) Uploading

• Connect to the hotspot created by the ESP12F.
• Launch Arduino, choose "esp at 192.168.4.1" as the port.
• If you don't see the port listed in Arduino (Tools > Port), restart Arduino IDE.

You can upload your sketch and files wirelessly, there is one caveat: SPIFFS file uploads don't work with password protected uploads (line 42). Workaround: flash your sketch with line 42 commented out. Upload your files to SPIFFS, then uncomment the line and Upload the code.
