Title: how to use the mcf52235 timer interrupt in the utasker
Post by: tr111 on March 10, 2008, 01:19:19 PM

   Did the utasker use all of the mcf52235 timer interrupt???
   I only want to use one mcf52235 timer interrupt!

Hi

The uTasker project for the M5223X uses the PIT (Periodic Interrupt Timer) as system TICK.
The second PIT is free.

If global HW timer support is activated (GLOBAL_TIMER_TASK and GLOBAL_HARDWARE_TIMER) it will additionally use one of the DMA timers - the one used is defined in app_hw_config.h by HW_TIMER_USES_DMA_TIMER

The other DMA timers are free.

Regards

Mark
