Then the value that must be entered in the integer will be shown to observe the desired pin. + +In case you do not want to show anything on that channel, just assign 00 so that the channel will not be written. +The pins that do not appear in the table can not be used because they were not considered in the arduino programming, to avoid overloading the +arduino and obtain more satisfactory response times. + +SPANISH +Funcionamiento de la asignacion de pines. +Dado que el arduino MEGA2560 tiene bastantes pines más que el arduino uno, y además su procesador puede llegar a los 2MHz y supongo también debe de tener un mejor ratio +IPC (Instrucciones por ciclo) decidí hacer lectura de 24 pines de los cuales deplegaremos 16 en el programa, entre las razones para hacer esto estan, la ubicacion de los +pines los cuales no siempre estan donde uno quisiera, y el mapeo de los pines digitales en el microcontrolador del arduino, ya que queria aprovechar la mayor cantidad de +pines haciendo la menor cantidad de instrucciones para no perjudicar el proceso. + +Las entradas se deplegaran en el orden que aparezcan en el entero PinAssignment que va del 0 al 15 para un total de 16, el valor del entero en cada posicion referenciara +el pin a utilizar. A continuacion se mostrara el valor que se debe introducir en el entero para observar el pin deseado. + +En caso de no querer mostrar nada en ese canal basta con asignar 00 para que el canal no sea escrito. +Los pines que no aparecen en la tabla no podrán ser utilizados por que no fueron considerados en la programacion de arduino, esto para evitar sobrecargar al +arduino y obtener tiempos de respuesta más satisfactorios. + +EN Number of Pin in the Arduino Mega Number to enter in the PinAssignment +ES Numero de Pin en el Arduino Mega Numero a introducir en el PinAssignment +Digital PIN 22 -------------------------------------------------------> 10 +Digital PIN 23 -------------------------------------------------------> 11 +Digital PIN 24 -------------------------------------------------------> 12 +Digital PIN 25 -------------------------------------------------------> 13 +Digital PIN 26 -------------------------------------------------------> 14 +Digital PIN 27 -------------------------------------------------------> 15 +Digital PIN 28 -------------------------------------------------------> 16 +Digital PIN 29 -------------------------------------------------------> 17 +Digital PIN 49 -------------------------------------------------------> 20 +Digital PIN 48 -------------------------------------------------------> 21 +Digital PIN 47 -------------------------------------------------------> 22 +Digital PIN 46 -------------------------------------------------------> 23 +Digital PIN 45 -------------------------------------------------------> 24 +Digital PIN 44 -------------------------------------------------------> 25 +Digital PIN 43 -------------------------------------------------------> 26 +Digital PIN 42 -------------------------------------------------------> 27 +Digital PIN 37 -------------------------------------------------------> 30 +Digital PIN 36 -------------------------------------------------------> 31 +Digital PIN 35 -------------------------------------------------------> 32 +Digital PIN 34 -------------------------------------------------------> 33 +Digital PIN 33 -------------------------------------------------------> 34 +Digital PIN 32 -------------------------------------------------------> 35 +Digital PIN 31 -------------------------------------------------------> 36 +Digital PIN 30 -------------------------------------------------------> 37 + + + +*/ + +//buttons and others +int button1X = 8; +int button2X = 8; +int button3X = 80; +int button4X = 200; +int button5X = 270; +int buttonY; +int buttonH = 20; +int smallButtonW = 50; +int bigButtonW = 100; +int graphBoxH; +int textBoxH; +int immage = 1; +int corner = 10; +String s; +boolean initial=true; + +// bar scroll +int handleFill = grey; +float handleX; +float handleY; +float handleW = 20; +float handleH = 15; +boolean isDraggable = false; + + + +void setup () { + //p = new Serial(this, Serial.list()[0], 115200); + p = new Serial(this, LA_port, baudrate); + p.bufferUntil('\n'); + + size(1300, 700); + background(black); + smooth(4); + xShift=(width-handleW)/2; + //Here you chose the pins that yuo want to show in the Logic Analizer.
