Multi Calculator Kit

[teenix]

Hi all,

A new MultiCalc update is available from teenix.org.

I have added a programmable timer that will put the calculator into low power idle mode when the timer expires. The timer can be programmed to provide 1 to 10 minute delay, or it can be disabled. The default setting is 5 minutes.

On timer expiry, the calculator will halt its operation and turn off the display. When any key is pressed, the calculator will resume whatever it was doing.

The idle timer is temporarily disabled while the HP45 or HP55 timer is active.

This function has not been implemented for Haralds module because, even if the PIC shuts down, Haralds module and the original HP display circuitry still draws a reasonable amount of battery current.

cheers

Tony
