STM8S-Discovery

Runs real hand-assembled STM8 firmware on a from-scratch 8-bit STM8 core (an STM8S105 on the STM8S-Discovery board). Pick a program with the ROM selector. The on-board green LED LD1 is on PD0; the user/touch key is on PB7; UART output goes to the serial console at the bottom. "Blink LED" blinks LD1; "Button toggles LED" toggles LD1 on each press of the KEY button — hold or click it in the Controls window; "Timer blink" paces LD1 off the TIM4 update flag; "UART hello + counter" prints a greeting and an incrementing counter over UART2. Open the debugger, or add ?debug, to single-step the STM8, read A/X/Y/SP/PC/CC and the V/I1/H/I0/N/Z/C flags, disassemble the flash at 0x8000 with the new STM8 decoder (with its 0x72/0x90 prefix bytes) and set breakpoints and write watchpoints. The board has no on-board speaker, so it is honestly silent.
