Propeller 2

Runs real hand-assembled Parallax Propeller 2 (P2X8C4M64P) PASM2 on a from-scratch 8-cog core. Pick a program with the ROM selector. The on-board surface is an eight-LED bank on pins P56..P63 (the Parallax P2 Eval Board's blue user LEDs), driven by real DIRB/OUTB writes and the P2 pin instructions (DRVH/DRVL/DRVNOT/OUTH/OUTL). "Blink one LED" toggles P56 with DRVNOT paced by WAITX; "Knight-rider LED chase" sweeps a single lit LED back and forth across all eight; "Binary counter" shows a live binary count on the bank; "CORDIC sine VU bar" feeds an angle to the P2 CORDIC solver with QROTATE, reads Y=amp*sin with GETQY and lights a bar that rises and falls with the sine wave; "Smart pin blinks the LED" configures smart pin P56 with WRPIN/WXPIN, enables it with DIRH and then idles while the smart-pin hardware toggles the LED on its own; "Two cogs, two LEDs" launches a SECOND cog with COGINIT (loaded out of hub RAM) that blinks P63 in parallel with cog 0 blinking P56 — watch the C0/C1 lamps light. Open the debugger, or add ?debug, to single-step cog 0, read its PC / C / Z flags, the CORDIC QX/QY registers and the P2 special registers PA/PB/PTRA/PTRB/DIRA/DIRB/OUTA/OUTB/INA/INB, disassemble the cog RAM with the new Propeller 2 decoder and set breakpoints and hub write watchpoints. The P2 board here has no on-board speaker, so it is honestly silent.
