/* PROJECT FUGU FIRMWARE V1.10 (DIY 1kW Open Source MPPT Solar Charge Controller)
By: TechBuilder (Angelo Casimiro)
FIRMWARE STATUS: Verified Stable Build Version
(Contact me for the experimental beta versions)
-----------------------------------------------------------------------------------------------------------
DATE CREATED: 02/07/2021
DATE MODIFIED: 30/08/2021
-----------------------------------------------------------------------------------------------------------
CONTACTS:
GitHub - www.github.com/AngeloCasi (New firmware releases will only be available on GitHub Link)
Email - casithebuilder@gmail.com
YouTube - www.youtube.com/TechBuilder
Facebook - www.facebook.com/AngeloCasii
-----------------------------------------------------------------------------------------------------------
PROGRAM FEATURES:
- MPPT Perturbed Algorithm With CC-CV
- WiFi & Bluetooth BLE Blynk Phone App Telemetry
- Selectable Charger/PSU Mode (can operate as a programmable buck converter)
- Dual Core ESP32 Unlocked (using xTaskCreatePinnedToCore(); )
- Precision ADC Tracking Auto ADS1115/ADS1015 Detection (16bit/12bit I2C ADC)
- Automatic ACS712-30A Current Sensor Calibration
- Equipped With Battery Disconnect & Input Disconnect Recovery Protection Protocol
- LCD Menu Interface (with settings & 4 display layouts)
- Flash Memory (non-volatile settings save function)
- Settable PWM Resolution (8bit-16bit)
- Settable PWM Switching Frequency (1.2kHz - 312kHz)
-----------------------------------------------------------------------------------------------------------
PROGRAM INSTRUCTIONS:
1.) Watch YouTube video tutorial first before using
2.) Install the required Arduino libraries for the ICs
3.) Select Tools > ESP32 Dev Board Board
4.) Do not modify code unless you know what you are doing
5.) The MPPT's synchronous buck converter topology is code dependent, messing with the algorithm
and safety protection protocols can be extremely dangerous especially when dealing with HVDC.
6.) Install Blynk Legacy to access the phone app telemetry feature
7.) Input the Blynk authentication in this program token sent by Blynk to your email after registration
8.) Input WiFi SSID and password in this program
9.) When using WiFi only mode, change "disableFlashAutoLoad = 0" to = 1 (LCD and buttons not installed)
this prevents the MPPT unit to load the Flash Memory saved settings and will load the Arduino variable
declarations set below instead
