Digital Rotart Encoder -- Broken? Or am I misunderstanding how it works?

-

hi,

i apologize if seems fundamental question, feel i'm missing fundamental understanding digital rotary encoders, because none of basic encoders working expected.

these encoders i'm working with. link encoders

based on fundamental understanding of encoder, it's double switch 1/4 cycle out of phase. @ times, 1, 2, or 0 of encoder pins connected base pin.


given this, seems resistance between pins should either 0 or inf? correct? depending on current position of encoder?

if multi-meter showing 0 resistance (closed switch), , if move encoder 2 clicks, should show inf resistance pin 1 , base, correct?



i'm losing hair becuase have several encoders acting same way....always showing inf resistance between pins time.


please show me i'm doing wrong.


note:   i'm hooked the pins on side 3 pins. pin 1 , 3 encoder pins , pin 2 base pin.

with encoders there full cycle of pulses between 2 "clicks" or detents of encoder.  if measure state , click 2 clicks in direction should still in same resting state.  put scope on or use arduino give pin states turn it.  you'll see them changing between clicks.

Flip address is out of range arduino uno r3

hello  guy, trying flash firmware on arduino uno rev3 atmega 16u2 using atmel flip. whenever try , import .hex file program, throws error " address out of range ." have looked around online , haven't found solution. , info helpful. here hex file : https://github.com/nicohood/hoodloader2/blob/master/avr/bootloaders/hexfiles/hoodloader2_0_5_uno_atmega16u2.hex its using arduino uno hid Arduino Forum > Using Arduino > Installation & Troubleshooting > Flip address is out of range arduino uno r3 arduino

Arduino DUE ADC to DAC Piezo 30 Khz-100Khz

i working on project providing echo response ultrasonic sensors. piezo facing opposite ultrasonic sensor,with foam material in between damp ultrasonic signal reflecting sensor. event based,read piezo signal[(+) --> a0,(-) --> gnd on arduino due] , after delay(5 ms) drive same piezo through dac0 [(+)---> dac0,(-)--> gnd) so ultrasonic sensor receives signal (30 khz-100 khz) after delay,thereby calculating distance after time of flight of 5 ms. int in_adc0,out_dac0;  //variables adc,dac values (adc0, dac0) void setup() {   //adc configuration   adc->adc_mr |= 0x80;   // dac in free running mode.   adc->adc_cr=2;         // starts adc conversion.   adc->adc_cher=0x80;  // enable adc channels 0     analogreadresolution(12);  analogwriteresolution(12);   //dac configuration   analogwrite(dac0,0);  // enables dac0   serial.begin(9600); }   void loop() { ...

Indesign and MathType fonts

i having trouble getting indesign recognize mathtype fonts.  have been told move mathtype fonts on 2 indesign font folder.  copied mt-extra font file mathtype folder , pasted indesign font folder.  nothing changed.  indesign still gives me blank box after copy mt-extra font mathtype -->illustrator-->indesign.   guess need instructions on how transfer of fonts done correctly.  i'v looked @ install fonts manual indesign, not clear me on how it.  need utility fontexplorer this, or there other way.  what's weird working fine until had reinstall osx , reinstall cs3, font trouble started.  need toggle "activate-reactivate' adobe cs3 , don't know how close 20 max on this, worried that.  (i suspect because of note on forum might necessary).  thoughts appreciated. i'm using windows, advice may worth nothing...   1) shouldn't have deactivate id recognize fonts. 2) design science gives fonts away in type 1 , truetype flavors....
