Linux中regulator测试命令

在Linux系统中，"regulator"通常指的是电压调节器，这是一种硬件组件，用于管理电池或其他电源设备中的电压供应。如果你想测试或操作系统中的电压调节器，你可以使用一些特定的命令行工具，但这些工具可能会因内核版本和具体的设备驱动程序而异。

一个常用的命令行工具是`vcgencmd`，它是一个从Linux kernel提供的cmdline工具集，用于查询和控制一些硬件信息，包括电压控制器。例如，你可以运行：

# 查询电压调节器状态
vcgencmd get_voltage < regulator_name>

# 设置电压
vcgencmd set_voltage < regulator_name > < voltage_value_mV >

# 列出所有的电压调节器
vcgencmd list_voltages

linux regulator

Linux regulator是一个用于管理电源的子系统，它可以控制电压、电流和功率等参数，以确保系统的稳定性和可靠性。它可以与硬件平台上的各种电源管理器件（如DC-DC转换器、LDO等）进行交互，从而实现对系统电源的精确控制。Linux regulator还提供了一套API，使得开发人员可以方便地访问和配置电源管理器件，以满足不同应用场景的需求。

max20087 regulator linux driver

As an AI language model, I don't have access to specific code or driver implementations. However, I can provide you with some general information about the max20087 regulator and its Linux driver.

The MAX20087 is a high-voltage, low-quiescent current linear regulator that can operate with input voltages up to 60V. It provides a fixed output voltage and is suitable for use in a wide range of applications, including automotive, industrial, and communications systems.

In Linux, the MAX20087 regulator is supported by the max20087 driver, which is included in the mainline kernel since version 5.14. The driver provides a sysfs interface that allows users to control the regulator's voltage and enable/disable it.

To use the max20087 regulator driver, you need to enable the CONFIG_REGULATOR_MAX20087 kernel configuration option and build the driver as a loadable module or built-in. Once the driver is loaded, you can access the regulator through the sysfs interface (/sys/class/regulator/regulatorX), where X is the regulator's ID.

You can also use the regulator framework in your application code to interact with the max20087 regulator driver. The framework provides a set of functions and data structures that simplify the process of working with regulators in Linux.

Overall, the max20087 regulator driver is a straightforward and easy-to-use component of the Linux kernel that provides reliable voltage regulation for a wide range of applications.
