Aardvark#

class Aardvark(serial_number: str | None = None)[source]#

Bases: I2CDriverBase

Total Phase Aardvark I2C/SPI host adapter. Connection params captured in __init__; USB opens on open().

serial_number (e.g. "2239-764425"); None lets pyaardvark pick the first available adapter.

Methods

`close`	Close the adapter handle.
`open`	Open the adapter (typically a USB host adapter) and prepare it for transactions.
`read`	Read `length` bytes from the 7-bit `address` (master read transaction).
`set_bitrate`	Set the master clock rate in kHz.
`set_power_enable`	Enable or disable target-power output on the adapter (where supported).
`set_pullups`	Enable or disable the adapter's internal bus pull-ups (typical: ~10 kΩ to VCC).
`write`	Write `data` to the 7-bit `address` (master write transaction).
`write_read`	Write `data` then immediately read `read_len` bytes from `address` using a repeated START.

open() → None[source]#: Open the adapter (typically a USB host adapter) and prepare it for transactions.

close() → None[source]#: Close the adapter handle. Idempotent.

read(address: int, length: int) → bytes[source]#: Read length bytes from the 7-bit address (master read transaction).

write(address: int, data: bytes) → None[source]#: Write data to the 7-bit address (master write transaction).

write_read(address: int, data: bytes, read_len: int) → bytes[source]#

Write data then immediately read read_len bytes from address using a repeated START.

Used for register reads: write the register address, then read its contents without releasing the bus. No STOP is issued between the write and the read.

set_bitrate(bitrate: int) → None[source]#: Set the master clock rate in kHz. Drivers may snap to the nearest supported rate.

set_pullups(enable: bool) → None[source]#: Enable or disable the adapter’s internal bus pull-ups (typical: ~10 kΩ to VCC).

set_power_enable(enable: bool) → None[source]#: Enable or disable target-power output on the adapter (where supported).
