Specifying the library dependencies in the depends field of library.properties causes the Arduino Library Manager (Arduino IDE 1.8.10 and newer) to offer to install any missing dependencies during installation of this library. "arduino-cli lib install" will automatically install the dependencies (arduino-cli 0.7.0 and newer).
…SemaphoreTake/Give and correcting some typos The xSemaphoreTake(_xSemaphore, portMAX_DELAY); in LED_Display::displaybuff was taking a second time the _xSemaphore that had already been taken in LED_Display::run() in the same execution flow and was halting the execution of the program xSemaphoreGive(_xSemaphore); in LED_Display::displaybuff has also been removed To keep things consistent, the FastLED.setBrightness(20); has been put after FastLED.show(); in LED_Display::run Some english typo were also corrected
…k-and-some-typos Update and rename Display.cpp, removing the blocking xSemaphoreTake
…of numeric constant Minor typo corrections to match those of LED_Display.cpp
With the previous code, the initial state (_count_x,_count_y) = (0,0) was never displayed. Here the buffer is calculated before the increment/decrement. As a side effect the total animation count shall be increased by one unit to display the last line
Following change in LED_Display.cpp to display the initial state, another 1 count is necessary to display the M fully.
int8_t offset limits scrolling to 127 whereas it is supposed to be able to be incremented or decremented several times the pixel size of the initial buffer
to allow large matrix scrolling. Also deleted unused declaration
Large matrix scrolling
Update type of setdatax and setdatay to allow display of large matrix
Corrected max number of LEDs with #define NUM_LEDS value
Initial state never displayed

So this is months old, why hasn't someone from M5Stack at least commented on this? Merge it? |

Wish I'd seen this earlier - I suspected a major bug in the animation code and was confused by the use of a semaphore. I wrote my own horizontal scroller logic (which is all I needed) to work around the issues in my own project Atomic Text. I'm somewhat shocked too that this hasn't been merged in either or the Atom library itself updated since January. |

Actual library LED_Display animations are not working due to blocking semaphore
The initial state (offset 0,0) of the buffer is never displayed in animations
Large buffer matrix can not be displayed or wrapped around due to limited offset type
Various minor english typo corrections
