Shit's Not Working

Good. Now the experiment has begun. Debugging works best when you stop changing five things at once and reduce the system to power, cable, board, port, bootloader, and one known-good sketch.

Some USB cables provide power but no dataThe selected board must match the hardwareESP32-S2 native USB can lose its serial portBOOT/DFU + RESET can enter the ROM bootloader

RESEARCH SIGNAL FLOWpower → data cable → board → port → bootloader → Blink → one change at a time

MYCOTUNE USE CASES

◌ Recover a missing serial port

◌ Separate firmware failure from wiring failure

◌ Return to Blink before blaming the ADS1115

◌ Write down the exact error instead of summarizing it as 'broken'

NEXT BENCH STEPS

→ Remove sensors and external wiring

→ Try a known data cable and another USB port

→ Hold BOOT/DFU, tap RESET, then release BOOT

→ Select the bootloader port, upload Blink, then press RESET
