You can now actually use it as a “standalone” blackmagic probe ;) Next up, include a “emulated” stm32, you know, when you don’t have a real device - wires around for testing

The build is based on litui’s work. With some fixes /confirmations/addons(cardputer) New features not in litui. On-device keyboard REPL so you can type BMP monitor commands directly on the Cardputer keyboard. 50-line scrollable history buffer with Fn+; and Fn+. navigation. Command output mirrored to USB CDC UART port simultaneously with on-screen display. GDB DTR debounce filtering Windows CDC enumeration transients that would suppress the keyboard REPL. Dirty-flag rendering so the display only redraws on keypress, eliminating flicker without needing double buffering. Startup logo splash screen. Cardputer-specific sdkconfig.defaults.cardputer with all display geometry, rotation, and SPI settings empirically confirmed on real hardware. Still not working, same as litui. JTAG, WiFi and networking, NV storage, CMSIS-DAP. Not yet tested on real hardware. Actual SWD target scan and attach (Grove wires in transit), RTT messages, semihosting.
