Lookout: How do you clear Ascii RSV1-512 Data Members

[mchen]

We have a proximity reader connected to the serial port and when a card is read the Lookout Ascii Object grabs the data. 

I connected a "pot"  to Ascii.RSV1 and setup the "pot" reset/resetvalue to equal 0 when necessary. Everything 

works OK providing a different card is used, if the the same card number is used the "pot" will not update due to data

remaining the same value. 

Is there a way to set Ascii RSV1 to zero in between reads or tell when new data has been sent?

You can monitor the Ascii.update. Whenever there is a new data coming in, "update" is pulsed.

That works, however the Ascii.update remains high long after the reader has sent the data. What's the best way to clear the Ascii.update signal?

[Ryan.S]

The update datamember cannot be cleared. But you can use the OneShot object. Connect update to OneShot.On/Off, and give a duration such as 1 second. It will be ON for only one second.

Thank you , that worked perfectly... I did not realize the Ascii.update was in fact changing state each time the serial port was sending data.
