MSP430 Salvo OS

For issues specific to TI's MSP430 line of ultra-low-power microcontrollers, including compilers (e.g. Quadravox AQ430), IDEs (e.g. IAR Embedded Workbench) and development tools (e.g. TI MSP-FET430 Flash Emulation Tool).

MSP430 Salvo OS

Hello,

I'm planning to design with the MSP430F133 with one Timer used as a divider.
The Salvo OS can use the second Timer. In order to avoid contention which Timer does the OS use?

Regards,
Leonard

Salvo's timer functions are implemented via OSTimer(). You can call OSTimer() any way you wish, using any timer available.

Note that OSTimer() is very fast -- maybe 20 instructions. Some Salvo Pro users call OStimer() from a high-rate interrupt at a lower rate by using Salvo's timer prescalar.

In any case, you won't have any contentions, since you can call OSTimer() however you wish.

Thanks for the info!

Which of the two Hardware Timers in the MSP430 does the OS use?
