Top  Previous  Next

The PG2051 is a serial comport based programmer and can program AT89C1051 and ATC2051 chips only. A nice feature is that the programmer can serve as an simulator too. The programmer works with Intel HEX files only.


The following menu options are available:


File Exit

This will exit the programmer.


Buffer read from disk

This allows you to load a binary file from disk.

The current projects binary file is always loaded automatic.


Buffer write to disk

This option can be used to save the buffer to disk.


Buffer download

With this option you send the programs' hex file to the programmer/simulator.

After it is sent, you can program the chip or simulate the program.

Buffer verify
