Uart Driver Free Rtos Demo
When running the ARM Cortex-A application with the FreeRTOS BSP example/demo. It prints the “Hello World” message to the ARM Cortex-M4 terminal using the BSP UART drivers. The purpose of this demo is to show how to use the UART and to provide a simple project for debugging and further development. The Linux driver creates a tty node. Uart Driver Free Rtos Demo. This is particularly true of comtest.c (which uses an example UART driver), which is generally written with the intent of stressing (and therefore testing) the RTOS kernel implementation rather than providing an example of an optimal solution. The demo application does.
Hi I'm trying to use the OpenPicus devKit for a project I am working on and to my understanding the IDE, upon new project creation, creates code that basically utilizes FreeRTOS and OpenPicus libraries.
What I am trying to figure out is how to use interrupts with the FreeRTOS kernel, or through OpenPicus (i dont think this is possible). I have read that the ISRs in FreeRTOS can be specified with the __attribute__ ( ( signal ) ) directive but how are they linked to specific interrupts?(uart or even a pin just going high?)

Interrupt handling is architecture, and often compiler specific rather than specific to FreeRTOS. FreeRTOS itself only defines what RTOS calls are valid in an ISR.

The OpenPicus hardware uses a PIC24. The FreeRTOS demo code for PIC24 includes a timer interrupt and serial interrupt examples in [..]DemoPIC24_MPLABtimertest.c and [..]DemoPIC24_MPLABserialserial.c respectively. The examples use Microchip's PIC24 compiler syntax. If you are using an alternative compiler, you will need to consult its documentation.
