Does the library support ESP32 RTOS tasks? #954
-
|
I am failry new to working with ESP32 and RTOS but aware having multiple tasks writing to the tft screen at once is a potential issue. At the moment I have it working ok but getting a corrupt screen at random times so wanted to check with you first if there was a best practice or example of how to manage this ? The library is working great apart from that thanks. |

The library is not thread safe. One user posted that it works when run as a single task, but this is not something I have tried so am unable to provide help. You may need to migrate away from Arduino TFT libraries to find a thread safe one. |

Thanks for getting back so quickly. I had a dig into the FreeRTOS documents and have added a global semaphore handle (mutex)(SemaphoreHandle_t xSemaphore4tft;) and then within each of the tasks that are running added an if( xSemaphoreTake( xSemaphore4tft, ( TickType_t ) 100 ) == pdTRUE ) before the tft activityand an xSemaphoreGive( xSemaphore4tft ) immediately after which has been working flawlessly. Thanks. |
