Hello everyone,  
I’m wondering if it’s possible to use FreeRTOS on a Microchip PIC 18F4431.

Can you tell me where I can find a list of the supported microcontrollers please?

Thank you for your time.

Hello @hs2 thank you for your answer. In the first link I found only the PIC18F452. Does it mean that the others 18F versions are not supported?

Instead in the second link there isn’t any 18F PIC.

Unfortunately I’m not very familiar with PICs but isn’t the PIC18F _family_ supported ?  
Did you already check [FreeRTOS - Microchip PICmicro (PIC18) RTOS Port. This page describes the free RTOS demo source code project for the Microchip PIC18 microcontroller.](https://www.freertos.org/a00097.html) ?  
If the PIC18F variants use the same CPU and have compatible timers (1 is needed for the FreeRTOS systick) it should be supported.
