Look in the FreeRTOS\Demo\msp430_IAR\serial directory of the FreeRTOS
download - there is a very basic UART driver that has an interrupt that
interacts with the kernel. Generally GCC is the only compiler that
allows the whole thing to be done in C *if* you want the ISR to be able
to cause a context switch.

But I have one more question? How to write ISR for MSP430 using IAR and
FreeRTOS. I tried to use #pragma directive but it not works. The problem is
that there is no examples of ISR interacting with FreeRTOS. I looked for
TickISR in FreeRTOS and it is written in assembly, and I would like to
write my ISR in C...
Please help....
