Inheritance diagram for Adafruit_EyeLights_buffered:
Public Member Functions | |
| Adafruit_EyeLights_buffered (bool withCanvas=false, IS3741_order order=IS3741_BGR) | |
| Constructor for Adafruit_EyeLights_buffered object. More... | |
| void | drawPixel (int16_t x, int16_t y, uint16_t color) |
| Adafruit GFX low level accessor - sets an RGB pixel value on buffered EyeLights LED matrix. No immediate effect on LEDs, must follow up with show(). More... | |
| void | scale () |
| Scales associated canvas (if one was requested via constructor) 1:3 with antialiasing & gamma correction. No immediate effect on LEDs; must follow up with show(). Note that this overwrites ALL pixels within the matrix area, including those shared with the rings. This is different than using normal drawing operations directly to the low-resolution matrix, where these ops are "transparent" and empty pixels don't overwrite the rings. | |
 Public Member Functions inherited from Adafruit_EyeLights_Base | |
| Adafruit_EyeLights_Base (bool withCanvas) | |
| Constructor for Adafruit_EyeLights_Base object. This is used internally by the library, not user code. More... | |

| void | fill (uint16_t color=0) |
| Sets all pixels of a buffered-and-GFX-subclassed object. Saves us implementing this in every subclass. More... | |
| Public Member Functions inherited from Adafruit_IS31FL3741_buffered | |
| Adafruit_IS31FL3741_buffered () | |
| Constructor for buffered IS31FL3741. LED data is stored in RAM and only pushed to device when show() is explicitly called. | |
| bool | begin (uint8_t addr=IS3741_ADDR_DEFAULT, TwoWire *theWire=&Wire) |
| Initialize I2C and IS31FL3741 hardware, clear LED buffer. More... | |

| Public Member Functions inherited from Adafruit_IS31FL3741 | |
| Adafruit_IS31FL3741 () | |
| Constructor for IS31FL3741 LED driver. | |
| bool | begin (uint8_t addr=IS3741_ADDR_DEFAULT, TwoWire *theWire=&Wire) |
| Initialize I2C and IS31FL3741 hardware. More... | |
| bool | reset (void) |
| Perform software reset, update all registers to POR values. More... | |
| bool | enable (bool en) |
| Enable/disable output via the shutdown register bit. More... | |
| bool | unlock (void) |
| Allows changing of command register by writing 0xC5 to 0xFE. More... | |
| bool | setGlobalCurrent (uint8_t current) |
| Set global current-mirror from 0 (off) to 255 (brightest). More... | |
| uint8_t | getGlobalCurrent (void) |
| Get the global current-mirror register setting. More... | |
| bool | setLEDscaling (uint16_t lednum, uint8_t scale) |
| Set the scaling level for a single LED. More... | |
| bool | setLEDscaling (uint8_t scale) |
| Set the scaling level for all LEDs. Optimized for fewer I2C transfers vs. setting each individually. More... | |
| bool | setLEDPWM (uint16_t lednum, uint8_t pwm) |
| Set the PWM level for a single LED. More... | |
| bool | fill (uint8_t fillpwm=0) |
| Set the PWM value for all LEDs - great for clearing the whole display at once. Optimized for fewer I2C transfers vs. setting each individually. More... | |
| void | show (void) |
| Empty function makes direct & buffered code more interchangeable. Direct classes have an immediate effect when setting LED states, only buffered ones need an explicit call to show(), but it gets annoying when moving code back and forth. So this does nothing in the direct case. For code that you KNOW will always be strictly unbuffered, don't call this, it sets a bad precedent. | |
