Can FreeRTOS for MSP430 in Continuous Mode

Hello,
I just want to know FreeRTOS for MSP430 can work in Continuous Mode.
Currently it is working in Up mode with 1 ms as context switch time.
If I can do the same thing with continuous mode, will that cause any problem?

Sorry - can’t help - I don’t know what “continuous” and “up” modes are.

Regards.

Thank you for your reply.
I just want to know whether FreeRTOS requires any timer interrupt with 1 ms interrupt

The tick interrupt can come from any source that can generate it. The tick speed does not need to be 1 ms, but is configured.

Thank you for your answer woops_. Can you tell me what is a typical context switch time for FreeRTOS

rtel wrote on Friday, June 15, 2012:

There isn’t a typical time, just as there isn’t for any RTOS.  It depends on the architecture, clock speed, compiler optimisation level, FreeRTOS configuration (are you checking stack overflow?), etc.  If it is important to you then create a configuration you want to actually use, and count the instruction cycles taken.

Regards.
