UCSIM(1)

💖 NAME 💖

okay so welcome to the UCSIM(1) page from the General Commands Manual, bestie — this is uCsim, aka the Micro-controller simulator. It's giving simulator-for-several-processor-families realness. You start it as a ucsim_XXXX command, where XXXX tells it which simulated processor type you want. Eg. ucsim_51 starts the Intel MCS51 microcontroller simulator, ucsim_z80 starts the Zilog Z80 microprocessor simulator, etc. iconic behavior ✨

🌸 DESCRIPTION 🌸

uCsim is a microcontroller, microprocessor simulator for several processor families. It can be started as ucsim_XXXX command, where XXXX specifies the simulated processor type. Eg. ucsim_51 starts Intel MCS51 microcontroller simulator, ucsim_z80 starts Zilog Z80 microprocessor simulator, etc. Slay, honestly. 💅

🎀 OPTIONS 🎀

Options of the command — yes bestie, all of them, no skipping. 🫶

• -a nr — Specify size of variable space (default=256).
• -A — Force use colored output, remove effect of -b and -q on colors.
• -b — Black & white (non-color) theme.
• -B — Beep on breakpoints.
• -c file — Open command console on file (use - for std in/out).
• -C file — Read initial commands from file and execute them.
• -e command — Execute command at program startup (after config file).
• -E — Go, start simulation in emulation mode.
• -g — Go, start simulation.
• -G — Go, start simulation, quit on stop.
• -h — Print out this help and quit.
• -H — Print out types of known CPUs and quit.
• -I options — options is a comma separated list of options according to simulator interface. Known options are:
  • if=memory[address] — turn on interface on given memory location.
  • in=file — specify input file for IO.
  • out=file — specify output file for IO.
• -k portnum — Use localhost:portnum for serial I/O. This option is obsolete, use -S instead.
• -l — Use colors of the light theme (default is dark).
• -m — Return value of simulated main() function.
• -o colors — List of color specification: what=colspec,... where colspec is a : separated list of color options e.g.: prompt=b:white:black (bold white on black).
• -p prompt — Specify string for prompt.
• -P — Prompt is a null ('\0') character.
• -q — Quiet mode, print less information (implies -b).
• -R seed — Set the random number generator seed.
• -s file — Connect serial interface uart0 to file. This option is obsolete, use -S instead.
• -S options — options is a comma separated list of options according to serial interface. Know options are:
  • uart=nr — number of uart (default=0).
  • in=file — serial input will be read from file named file.
  • out=file — serial output will be written to file.
  • port=nr — use localhost:nr as server for serial line.
  • iport=nr — use localhost:nr as server for serial input.
  • oport=nr — use localhost:nr as server for serial onput.
  • raw — perform non-interactive communication even on tty.
• -t cpu_type — Specifies type of the controller. Use -H to list possible values.
• -U uartnr — Use std console as terminal for UART id=uartnr.
• -u hw — Use std console as display for specified hw.
• -v — Print out version number and quit.
• -V — Verbose mode.
• -w — Writable flash.
• -X freq[k|M] — XTAL frequency in Hz, Use k or M suffix to specify frequency in kHz or MHz.
• -z portnum — Listen portnum for command console.
• -Z portnum — Listen portnum for command console (no console on stdio).

okay that's the whole UCSIM(1) page, bestie — the footer is just the manual name UCSIM(1) again, with no extra source/version or date line to spill, so consider this the cute sign-off instead. 💖✨
