Yukihiro "Matz" Matsumoto	b8eccc7a38	hw-i2c: consolidate platform gems into ports/ directories ... Move hw-esp32-i2c and hw-rp2040-i2c into hw-i2c/ports/esp32/ and hw-i2c/ports/rp2040/ using the new ports build system. Platform sources are now compiled automatically based on conf.ports setting. Separate platform gems are no longer needed. Co-authored-by: Claude <noreply@anthropic.com>	2026-04-23 19:25:36 +09:00
Yukihiro "Matz" Matsumoto	1ed52461e8	hw-i2c: add I2C peripheral gems for embedded platforms ... Add three new gems for I2C communication: - hw-i2c: common Ruby API, C bindings, and HAL header - hw-esp32-i2c: ESP32 HAL using ESP-IDF I2C master driver - hw-rp2040-i2c: RP2040 HAL using Pico SDK The HAL API provides init, read, write, and atomic write_read (repeated START) operations. Platform gems depend on hw-i2c and are only compiled when explicitly included in build config. Co-authored-by: Claude <noreply@anthropic.com>	2026-04-23 19:25:35 +09:00
