XPowersLib Example

Prerequisites

Please put XPowersLib and esp-idf in the same level directory, after configuring the esp-idf environment variable, enter XPowersLib/examples/ESP_IDF_Example and run the idf.py command directly

Configure the Project

Open the project configuration menu (idf.py menuconfig).

In the XPowers Configuration menu:

Select the PMU Type in the PMU_Type option.
In PMU SCL GPIO Num select the clock pin to connect to the PMU,the default is 22
In PMU SDAGPIO Num select the data pin connected to the PMU,the default is 21
Select the interrupt pin connected to the PMU in PMU Interrupt Pin, the default is 35

How to Use Example

Before project configuration and build, be sure to set the correct chip target using idf.py set-target <chip_name>.

Build and Flash

Run idf.py -p PORT flash monitor to build, flash and monitor the project.

(To exit the serial monitor, type Ctrl-].)

See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.

Example Output

The output information is to configure the output voltage and enable status of the PMU

Build process example

Assuming you don't have esp-idf yet

mkdir -p ~/esp
cd ~/esp
git clone --recursive https://github.com/espressif/esp-idf.git
git clone https://github.com/lewisxhe/XPowersLib.git
cd esp-idf
./install.sh
. ./export.sh
cd ..
cd XPowersLib/examples/ESP_IDF_Example
idf.py menuconfig
idf.py build
idf.py -b 921600 flash
idf.py monitor
