 		 #160187 - Reading a pot using a digital input???
Hello... some time ago I read in a web site something about reading a pot using one digital input of microcontroller, something like reading the time of discharge of the pot... I was searching for something like this, but the only thing I found was for pic... someone know something about this? Looks interesting for some simple projects where makes expensive to have an ADC

   And a cap            01/01/70 00:00      
      Forgot to say the capacitor!            01/01/70 00:00      
         Can you show us the corresponding link?            01/01/70 00:00      
            Shure!            01/01/70 00:00

                     it will still be only for a toy            01/01/70 00:00      
                     Begin with using two free P0 port lines, ...            01/01/70 00:00      
                        Can I measure the charge and discharge time of the cap?            01/01/70 00:00      
                           yes, no, maybe            01/01/70 00:00      
                              Two caps or comparator            01/01/70 00:00      
                                 Crap, also because of several other factors...            01/01/70 00:00      
         That is a PIC not an 8052            01/01/70 00:00      
            you need a pullup for this            01/01/70 00:00

   Link...            01/01/70 00:00      
   inconsistent readings            01/01/70 00:00      
      Filtering needed            01/01/70 00:00      
         even better            01/01/70 00:00      
            Not so critical            01/01/70 00:00      
   Why Not Put the Pot            01/01/70 00:00      
      I agree...            01/01/70 00:00      
         Something Like This            01/01/70 00:00      
            I guess, Chico needs it for an Midi application...            01/01/70 00:00
