settingsManager.h File Reference

Detailed Description

Design Philosophy

Settings are integers that control hardware peripherals and are persistent across reboots. Each setting has a bounded range and a default value.

The range and default value is stored in a settingParam_t, which does not change and should be declared const to compile into ROM. The setting is read from NVS and stored a setting_t in RAM so that modes and peripherals can quickly access it without disk operations. The DECL_SETTING() macro exists to easily and consistently declare the required variables for a setting.

Settings should immediately modify the hardware peripheral they control when changed.

An example of a setting is TFT brightness. The brightness is an integer (0-MAX_TFT_BRIGHTNESS), which controls a hardware peripheral (the TFT), and is persistent across reboots (once the brightness is set by the user, it should stay that way).

Settings rely heavily on, and can be thought of a wrapper around, hdw-nvs.h.

Settings can be easily added to menus with the function addSettingsItemToMenu(). Be sure to set the setting in the menuCb callback according to the new value.

Usage

Setting variables should be declared using DECL_SETTING() and giving the macro the minimum, maximum, and default values.

Settings should be modified using the static functions readSetting(), incSetting(), decSetting(), and setSetting().

Each setting should have it's own set of functions to be called from other files. For instance, getTftBrightnessSetting() is used to get the current TFT brightness level, getTftBrightnessSettingBounds() is used to get the setting bounds for menu construction, and setTftBrightnessSetting() is used to set a new TFT brightness value, which is used immediately.

readAllSettings() is called during system initialization to read all settings into RAM and set hardware peripherals accordingly.

Example

Adding a setting to a menu:

// Declare the label
static const char tftSettingLabel[] = "TFT";
 
// Add the TFT settings item to the menu. Initialize it by getting the parameters and current value
addSettingsItemToMenu(menu, tftSettingLabel, getTftBrightnessSettingBounds(), getTftBrightnessSetting());

Setting a setting from a menu callback

// Make sure the label matches
if (tftSettingLabel == label)
{
    // Set the setting to the reported value.
    // This will call setTFTBacklightBrightness(), setting the actual brightness as well
    setTftBrightnessSetting(settingVal);
}
