avr external interrupt false trigger -

-

I was programming for external interrupts using the ATmega 128. I divided the outer interval between 0 and 1, which triggered the rising edge. Calculate the number of times the switch is pressed in between. But when the key is pressed once, the interval is called 2 or 3 times and therefore it means more. What's the problem here?

My interrupt code is here 

  ISR (INT1_vect) {cli (); ++ push_cntr1; Printf ("p1:% d", push_cntr1); Sei (); } ISR (INT0_vect) {cli (); ++ push_cntr0; Printf ("p0:% d", push_cntr0); Sei (); } Zero interrupt_init (zero) // enabled between 0 and 1 enabled. {EICRA | = (1 & lt; iSC01) | (0  & lt; ISC00). (1 & lt; ISC11) | (0 > ISC10); EIFR = 0x FF; EIMSC | = (1 & lt; INT1) | (1 & lt; & lt; INT0); DDRD = 0x00; } Int main (zero) // main program {dev_init (); While (1) {process (); } Return 0; }    
 
 
 I need to clean and set up a little bit inside the handler is . It will be kept in mind by the compiler.  
 For many hits, you may be suffering from "switch bounce". There are many references to this on the web, but this means that the voltage in the switch circuit is not in a clean jump from 0 to the maximum. This is most often due to the actual physical flood of electrical contacts.  
 There are several techniques available to "debug" a switch. As you can see TCNT recording and ignoring the interrupt soon after the last one Can try a few simple ones.

Pass DB Connection parameters to a Kettle a.k.a PDI table Input step dynamically from Excel -

I have a requirement whenever I run my own kettle, dynamically took database connection parameters from an excel source Every run should go. I have an Excel column names: hostname, username, database, password. I want to pass these connection parameters to my table input stage dynamically whenever it runs the job. This is what I was trying to do. You can get it Connection parameters from the DB reading source (for example Excel or a CSV file in my example) < / Li> Store the parameters in the variable Using the variable in your connection's settings. Setting Variables Create another conversion for (you can not do it in the same conversion Uses): set variables element variable: The element that reads / writes your data creates a new connection and sets the connection parameter using $ {variable name_} Note that you will need to type in the field field in the field $ {password} Also keep in mind that this can be a security problem as the

I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ... " , Status {console.log ("open site:" + data [index B], position); / * OLD * / indexB ++; page evaluation (function () {// page scrape and an object Return}, function {console.log (result.dataRequest); // here is the problem}); / * new and fixed * / indexB ++} first console Logs it: Open Site: 100 Success Opens Site: 101 Success B Ola Site: 102 Success Opening Site: 103 Success Opened Site: 104 Success Which is good. Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
