Implementation Notes

Software and Dependencies:

class AXP313A.AXP313A(i2c)

The main class. Create an object by passing an i2c bus.

The bus does not need to be locked or ready at the time of creation.

begin() → bool

Check if the chip is ready and available.

Returns bool.

disable_power() → None

Set all the voltages to 0.

set_power(DVDD: float, AVDDorDOVDD: float) → bool

Sets the power to the specified voltages. If an incorrect voltage is set, you got a firework in your hands.

set_shutdown_key_level_time(offLevelTime: int) → None

An undocumented & unused function that was carried off from the dfrobot arduino / micropython modules.

Seems to affect button press time.

class AXP313A.camera_voltages

Contains preset values for specific camera sensors.

Currently, the supported cameras are: OV2640 and OV7725.

AXP313A.disable_camera(axpobject) → None

An alias for disable_power.

AXP313A.enable_camera(axpobject, camera: list) → bool

Quick function to enable power for a specific camera sensors.

Call like: enable_camera(my_axp, camera_voltages.OV2640)
