Hi, I am using Salvo on MSP430F2618 and my problem is that the build size of salvo is big for the size that i can allow for it to use.

when i use a single task with delay and yield functions the size of the code reaches 14.6 kB which is big for the since i have size constrains. I am not using any event queue for message queue. so is there any way for me to reduce the size below about 8 kB.For example can i remove Events and Messages from my salvo build. please tell me how to do it.

I am using only 10 tasks with priorities and OS_Delay() and OS_Yield() and createtask, stoptask , starttask functions and some more task and scheduling related functions.

Well, you don't need events, given what you have described ... so you can change e.g. to a delay-only library (-d), which will shrink the Salvo code.

However, keep in mind that in a 14KB application, Salvo will only be around 2-3KB ... so there's not that much to gain there. Your 14KB application size is not due to Salvo ...

For example, here's an MSP430F1611application (it controls a LiPo charger, and has a User Interface, etc., uses floating point, has large buffers, etc) -- Salvo accounts for only 2409 (0x5b27 - 0x51be) bytes of Program Memory in a total CODE size of 12,644 bytes:
