A compiler created for a programming language made by myself. This was part of a Six Semester proyect. The language has lexic, sintactic and semantic rules, too it traduces my language to arduino. Cause the language was maded to control a fan connected to an arduino by serial port.
Languages rules:
- All the vars are declared out of the initial method called "Proceso".
- Can't exists functions out of the "Proceso" method.
- Only can exist a method called "Proceso".
- The fan must be on before give it instructions.
- The "Proceso" method and the conditions must have open and close delimiters, containig the instructions to run.
- The comments can go anywhere.
- Only exists integeres datatypes.

int pin1=10;
int pin2=9;
int a=6; -> var declaration
Proceso () -> Principal process loop
< ->Open delimiter
Encender (pin1) ->Instructions and conditions
Velocidad (pin1:5)
Giro.Izquierda (pin1,pin2)
Retardo (5)
si (a>5) ->Condition expression
<
Giro.Derecha(pin2,pin1)
Retardo (10)
a-- ->Subtract operator
Token table
| No. | Token | Category | Function |
|---|---|---|---|
| 1 | int | Reserved word | Defines the datatype (integer) of the posterior assign expression |
| 2 | x=10 | Assign expression | Assign the value to a var defined by the user |
| 3 | Proceso | Reserved word | Default method that defines the process to run between the delimitators |
| 4 | () | Instruction parameters | Defines the parameters that a functions is receiving |
| 5 | < | Open delimiter | Defines that start of a block code to methods like "Proceso" and the "si" conditions |
| 6 | Encender | Reserved word | Turns on the fan reciving a parameter |
| (1) | Instuction parameters | Receives the parameters of the "Encender" instruction | |
| 7 | Velocidad | Reserved word | Defines the fan velocity |
| (1:10) | "Velocidad" parameters | Receives the pin where the fan is connected to and the velocity of the fan, splited by a ":" | |
| 8 | Retardo | Reserved word | Defines an await time before executes the next code |
| 9 | (5) | Instruction parameters | Receives a parameter which is the wait time in seconds |
| 10 | Giro.Derecha | Reserved word | Defines the fan turn direction to right |
| 11 | (1,2) | Fan turn direction parameters | Receives the connected fan pin to turn on and turn off to change the turn direction |
| 12 | Giro.Izquierda | Reserved word | Defines the fan turn direction to left |
| 13 | (2,1) | Fan turn direction parameters | Receives the connected fan pin to turn on and turn off to change the turn direction |
| 14 | si | Reserved word | Evaluates if a conditon is right or not to execute a code block |
| 15 | (x<10) | Condition expression | Receives a evaluation based on a declared user var or a number |
| 16 | x++/x-- | Add and substract operatores | Add or substract one to a defined var |
| 17 | > | Close delimiter | Defines the end of a code block |
