timer ticks ARM BASIC vs BASIC stamp

[YahooArchive]

Hi all,

With the BASIC stamp the actual CLK tics need to be truncated-scaled as in (from
PERL code):


$true_secs_per_tic = ($secs_per_tic/2)*2.304;
$num_tics = int ( ($num_tics/$true_secs_per_tic) + 1 );

Are there any issues for CLK adjustment timings I should be aware of with the
ARMmite?

thanks,

The TIMER in BASIC is set to increment every microsecond, no adjustment
necessary.

However, the time base for the ARMmite, PRO and ARMexpress is based on a ceramic
resonator which is 1% accurate.

The PROplus and SuperPRO use the internal oscillator which is trimmed to 1% at
NXP. But they also allow an external crystal to be added for better accuracy.

The DINkit uses an external crystal for 200 ppm accuracy.
