Uncomment if two-colour OLED screens are used. Uncomment when using a Heltec module as their implementation doesn't support setMTU()Ĭhoose and uncomment the type of OLED display that you use: 0.96' SSD1306 or 1.3' SH1106

Uncomment for better Bluetooth compatibility with Android devices Comment out if you'd prefer to not see so much text output Comment this out if you DO NOT have the expression pedal mod.ĭump preset define. Go you! Now you have a guaranteed charge indicator too.Įxpression pedal define.

You have the battery monitor mod described above AND you have a connection between theĬHRG pin of the charger chip and GPIO 33. Indicator of when the battery is charging. You can see an accurate representation of the remaining battery charge and a kinda-sorta You are monitoring the battery via a 2:1 10k/10k resistive divider to GPIO23.

You have no mods to monitor the battery, so it will show empty (default). Uncomment this to use with Android devices that are happier with classic BT code. Note, that some boards in Arduino IDE don't have Partition Scheme settings, in this case it's recommended to choose some other ESP32 board (ESP Dev Module, Heltec WiFi Kit 32, WEMOS LOLIN32, etc.) which has this menu.in Arduino IDE choose Tools->Partition Scheme->No-OTA(Large APP), or something that gives you around 2MB APP partition along with enough (also 2MB) of SPIFFS space, cause presets are stored there.

The program won't fit into a standard APP partition. Heltec ESP 1.1.1 (only for Heltec boards).Under Tools->Manage Libraries ensure that you have the following libraries and versions: Heltec ESP32 Dev-Boards 0.0.5 (Heltec - WiFi Kit 32) OR.Under Tools->Board->Board manager ensure that you have the following version:

Under Files->Preferences->Additional Boards Manager URLs, enter the following: Note: Currently there may be a problem with LittleFS compiling on the Arduino IDE 2.x. Format of *.json preset files is the same as backed up files, used by the Spark app (usually you can find them zipped in your Dropbox).Use the filemanager to upload your tone presets to the banks folders, 4 presets per folder.If everything is done correctly, holding BUTTON 1 on boot again will connect your pedal to your home WiFi network, and the OLED display on the pedal will show the address of the filemanager site, so you can access the pedal from any device connected to your local wireless network.Submit your local WiFi network credentials (SSID and password), so the pedal could connect to your home WiFi.Connect to this WiFi, using your mobile or PC or whatever.Initially the pedal will launch a WiFi Access Point (AP), SSID is 'SparkBox' by default.Holding BUTTON 1 during boot will switch the pedal to WiFi mode. On the first run your current set of hardware presets will be saved to the bank 000.If you stop scrolling for a few seconds, the selected bank will be uploaded to the amp. Long pressing BUTTON 2 or BUTTON 4 invokes Bank Select menu, continue using BUTTONS 2 and 4 to decrease/increase bank number.Holding BUTTON 1 during boot will switch the pedal to WiFi mode.Bypass mode, invoked by long pressing BUTTONS 3 and 4 simultaneously, allows adjusting effect levels to match your raw pickup output.Now with remote guitar TUNER display! Long press BUTTONS 1 and 2 simultaneously, or turn it ON from the app or on the amp.Long press BUTTON 3 to adjust current effect parameters: use BUTTONS 2 and 4 to decrement/increment, BUTTON 1 to cycle thru parameters and long press BUTTON 3 to save your edits back to the amp.Long press (more than 1s) BUTTON 1 to switch between Effect mode and Preset mode.Stand-by mode added to reduce power when disconnected - light or deep ESP32 sleep mode will be configured automatically depending on GPIOs of the buttons and logical levels choosen in your build.Also tested on WEMOS LOLIN32 Lite with battery support. Inter-operable with both conventional and Heltec ESP32 modules.Graphically display the effect state on the display.Switch on and off all four major effects dynamically.

Switch presets either on footswitch, app or Spark to update display.

Supports the most common DIY display types: SSD1306 and SH1106.

Allows connection of the app for full simultaneous control.

Uses BLE so that it can be used with music function of the Spark app.

Select 12 banks for four presets from the pedal.

Expression pedal input on GPIO34 for altering the current parameter or on/off switch.

Now with expression pedal input and a web interface for adding up to 12 banks for four presets. SparkBox is a BT pedal for the Positive Grid Spark 40.
