What

Updates CLAUDE.md hardware descriptions to the current SOL hardware revision, verified live on the CYRIL dev unit:

  • Audio: PCM1865 codec (I2S, ALSA card pcm1865) — was HiFiBerry DAC+ ADC
  • Display: ST7789V 240×240 TFT mapped via con2fbmap (fb1) — was Adafruit miniTFT + fbcp-ili9341
  • MCP3021 ADC primary I2C address is 0x4D (0x48 legacy fallback)

Verification

On-device: /proc/asound/cardspcm1865; /sys/class/graphics/fb1/namefb_st7789v; i2cdetect -y 10x4B (MP2624), 0x4D (MCP3021).

Docs-only.

Match the current SOL hardware verified on the CYRIL dev unit: PCM1865 audio
codec (I2S, ALSA card `pcm1865`) instead of HiFiBerry DAC+ ADC; ST7789V 240x240
TFT via con2fbmap instead of Adafruit miniTFT + fbcp-ili9341; and note the
MCP3021 primary address is 0x4D (0x48 legacy fallback).
