Turbo51 is a compiler for the programming language Pascal, for the Intel MCS-51 (8051) family of microcontrollers. It features Borland Turbo Pascal 7 syntax, support for inline assembly code, source-level debugging, and optimizations, among others. The compiler is written in Object Pascal and produced with Delphi.

In the 1980s, Intel introduced the 8051 as the first member of the MCS-51 processor family. Today, hundreds of cheap derivatives are available from tens of manufacturers. This makes the architecture very interesting for professionals and hobbyists. It is surprising that this 8-bit architecture is still in use today, and is still so popular. Of all 8051 compilers, several widely used C compilers exist, but only a few Pascal compilers. Turbo51 is available as freeware and was created with the goal to make a Pascal compiler for MCS-51 processors that will be as fast as Turbo Pascal, will use the same syntax and will generate high quality optimized code.

Language dialect

Turbo51 uses Borland Turbo Pascal 7 dialect. The syntax was extended with some constructs to support specific features of MCS-51 processors.

Var RS485_TX: Boolean absolute P3.2;

      I2C.SDA:   Boolean absolute P3.7;      I2C.SCL:   Boolean absolute P3.4;

      ModuleAddress:  Byte;      RX_LedTimer:    Byte;      TX_LedTimer:    Byte;

      SavedOutput:    TOutputData IDATA;      OutputsAuxData: Array [1..8] of Byte IDATA;

"Hello World" example

Program HelloWorld;

Const

 Osc      = 22118400; BaudRate = 19200;

Var SerialPort: Text;

Procedure WriteToSerialPort; Assembler;

Asm

  CLR   TI  MOV   SBUF, A

@WaitLoop:

end;

Procedure Init;

begin

  TL1  := BaudRateTimerValue;  TH1  := BaudRateTimerValue;  TMOD := %00100001;    { Timer1: no GATE, 8 bit timer, autoreload }  SCON := %01010000;    { Serial Mode 1, Enable Reception }  TI   := True;         { Indicate TX ready }  TR1  := True;         { Enable timer 1 }

end;

begin

  Init;  Writeln (SerialPort, 'Hello world!')

end.
