can you do this with simple pointers somehow?

s2jesse

repeat   buttonCheck(right, rightState, rightPressed, rightReleased)  
    if rightPressed
      OutA[noparse][[/noparse]led] := ledOn      
    if rightReleased
     OutA[noparse][[/noparse]led] := ledOff            
 
 
 
 
PUB buttonCheck(button, buttonState, buttonPressed, buttonReleased) 
  if ina[noparse][[/noparse]button] <> buttonState 'if button has changed 
   'CHANGED               
    if ina[noparse][[/noparse]button]
      'PRESSED          
      buttonPressed:=1         
    else
      'RELEASED
      buttonReleased:=1 
  else
    'NO CHANGE    
    buttonPressed:=0  
    buttonReleased:=0                     
  buttonState := ina[noparse][[/noparse]button]

i want this little button meathod to work with multiple buttons and pass in which button i want to change the variable for... can i do that by doing something similar to what i have here with pointers to the variables? i already have the state,pressed, and released variables declared ahead of time.

Heres 1 way to do it

repeat 
   buttonCheck(right, @rightState, @rightPressed, @rightReleased)  
    if rightPressed
      OutA[noparse][[/noparse]led] := ledOn      
    if rightReleased
     OutA[noparse][[/noparse]led] := ledOff            
 
 
 
 
PUB buttonCheck(button, buttonStatePtr, buttonPressedPtr, buttonReleasedPtr) 
  if ina[noparse][[/noparse]button] <> long[noparse][[/noparse]buttonStatePtr] 'if button has changed 
   'CHANGED               
    if ina[noparse][[/noparse]button]
      'PRESSED          
      long[noparse][[/noparse]buttonPressedPtr] :=1         
    else
      'RELEASED
      long[noparse][[/noparse]buttonReleasedPtr] :=1 
  else
    'NO CHANGE    
    long[noparse][[/noparse]buttonPressedPtr] :=0  
    long[noparse][[/noparse]buttonReleasedPtr] :=0                     
  long[noparse][[/noparse]buttonStatePtr] := ina[noparse][[/noparse]button]

sweet worked thank you! now i just gotta figure out a debounce to toss in

Timmoore

When ina[noparse][[/noparse]button] changes, Save cnt, next time if 10ms has gone by, look to see if ina[noparse][[/noparse]button] is the same, if so change state

s2jesse

this must not be what you mean [noparse]:)[/noparse]· not quite workin... I totally get the concept.. but the implemention isnt gelling in my brain yet [noparse]:)[/noparse]

PUB buttonCheck(button, buttonStatePtr, buttonPressedPtr, buttonReleasedPtr) | lastDebounceTime 
  debounceDelay := 800_000
  
  if ina[noparse][[/noparse]button] <> byte[noparse][[/noparse]buttonStatePtr] 'if button has changed 
   'CHANGED
    lastDebounceTime := CNT                                                                     
    if ina[noparse][[/noparse]button]
      'PRESSED          
      byte[noparse][[/noparse]buttonPressedPtr]:=1         
    else
      'RELEASED
      byte[noparse][[/noparse]buttonReleasedPtr]:=1 
  else
    'NO CHANGE    
    byte[noparse][[/noparse]buttonPressedPtr]:=0  
    byte[noparse][[/noparse]buttonReleasedPtr]:=0                     
  if CNT - lastDebounceTime > debounceDelay 
    byte[noparse][[/noparse]buttonStatePtr] := ina[noparse][[/noparse]button]

I would make buttonstate have 4 values - pressed, not-pressed, maybepressed, maybenotpressed
make lastdebouncetime external - same as other paras

if state is not-pressed and ina[noparse][[/noparse]button] <> not-pressed
state := maybepressed
debouncetime = cnt
elseif state is maybepressed and cnt - debouncetime > delay
if ina[noparse][[/noparse]button] <> not-pressed
state = pressed

similar for other states
