alt_alarm_start

I am trying to use alt_alarm_start() as a general purpose timer. My callback is not getting called at all. Status from my call is good. Could someone look at the following and give me some hints? ...

I think,

the timer used for the alarms is the System clock timer, which is set in the

System Library properties to a real timer in SOPC Builder.

(normally sys_clk_timer with resolution 1ms).

the resolution of the timer can be read by software with alt_ticks_per_second().
