…ci 2.13.13) bp.open_i2c() returns an I2CMaster (write/read/write_read/read_reg/write_reg/probe/scan/xfer); a NACK raises I2CNackError with nack_at. open_spi takes modes 1 and 2 on gateware v55+. capture_la(send=I2CSend|SpiSend|GpioSend) returns LaCapture.send_result and keeps 64 pre-trigger samples with an edge trigger. la_dir, pin_directions, apply_pin_directions; LaPinState dir/warn; DirectionConflictError; Capabilities.gateware.

…d (embeddedci-mcp 2.13.13) capture_la(send=...) runs one I2C, SPI or gpio transaction after the arm and triggers on its first line when no trigger is given. set_wiring sends the profile's pin directions. SPI tools take modes 1 and 2. Needs embeddedci 2.13.13. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Not done: HW e2e waits for the firmware release (gateware v55 is not released). No release.
