PIC16F8x simulator

This is a learning and developping interface written in PLT Scheme for the 8 bits MCU built by Microchip PIC16F8x.
Datasheet of component. Documentation in french and english are given with the package. Display is fixed 1024x768.
This Project is open source, and given not compiled. You need PLT scheme to run it.
Warning: Registers number in the real MCU are not 256 ! To produce real code, you need to stay between 0x0c and 0x50.

Features:

Programmable directly in PICasm
View of all registers in the same window
Inputs/Outputs are visible and modifiable
Output PORTB to parallel port (using a C program)
Variable speed of execution
Loading/Saving files
Interrupt handling
Assembling (hex code generation)
Disassembling from hex file into virtual scheme asm. - not yet implemented in GUI

Not supported:

EEPROM
WatchDog Timer
Config bits
Transfering to the PIC

Project stalled.

Updates 28-03-2004: (docs still not updated)
- fixed assembling.
- made hex2scheme function: takes a hex string and gives the scheme program runnable in the project.

Updates 19-01-2004: (docs not updated for this)
- fixed bug with ORG and NOP for missing lines.
- hex output bug fix with no END keyword at eof.
- inputs remade.
- load file remade.
- files are (really!) in plain text format.

Thanks to the PLT-scheme mailing list and Mr Roy :-)
