auto rang for show the signal .

max show 5 volt .

show offset in volt .

show the peek volt .

show the duty cycle .

show the frequency .

240X128 T6963C GLCD or anything mikroe support .

for watch the signal i think it is min 5hz and max 5khz .

at the last lines you can change mode of show :
 for(ff=38;ff<241;ff++){
  T6963C_line(ff,adread[ff],ff+1,adread[ff+1],T6963C_WHITE);
  //T6963C_dot(ff, adread[ff], T6963C_WHITE);  //
 }
they both are in program :
just change them , if you want dot ( line is better for frequency ).

the input signal is an0 ( porta.0 ) .

the input is protected for +- volt for vcc+5 volt & vss-5 volt .

remember : if you want to see the voltage , you should see the peek .

if you need moor freq , you can just change it to dspic ( 30f2020 etc ) and goto over 50khz for show .

at the end of program :
 delay_ms(1000);
  goto sttt ;
you can change the time , faster show , or slower show . anything you want . you can do it .
