# opencoil-paracity: code
|
||
|
|
|
||
|
|
### 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.
