Conflict with RTOS

[MyVanitar]

Hi,

The library is very good but I saw it conflicts with the STM32 FreeRTOS. Please make a test. if I use the LCD functions inside an RTOS task, then the RTOS stops working.

Probably because the library uses HAL_Delay() which may interfere with the scheduler. Have you tried using osDelay() or vTaskDelay() instead?

Maybe, I have not tested it though, but I think it should be. I'll try

I replaced with HAL_Delay() with osDelay() in the header file, FreeRTOS still ended up in Hard Fault IRQ. Turns out I called Lcd_string() before osKernelInitialize() and so osDelay() wasn't available to the lib for calling yet. So replacing HAL_Delay() with osDelay() works just fine as long as you call the LCD write method after kernel init.

Just putting it out here, so it might help someone.
