1.OpenHarmony_Firmware\OH_SolarControl\ADS1X15文件夹下移植了ADS1X15 Arduino端驱动代码到OpenHarmony。电流检测使用ACS712模块,接入ADS1115的AIN1和AIN2接口,ADS1115通过I2C模块与Hi3861通讯。接入主要代码如下: #include"ADS1X15.h"hi_gpio_init();//GPIO模块初始化// 端口复用I2Chi_io_set_func(HI_IO_NAME...
This instructable will cover a project build for an Arduino based Solar MPPT charge controller. It has features like LCD display, Led Indication, Wi-Fi data logging and provision for charging different USB devices. It is equipped with various protections to protect the circuitry from abnormal condi...
The constrain function in the Arduino limits the PWM signal from going above the ceiling limit as well as from going below the floor limit. The function "ledcWrite(pwmChannel,PWM)" is the ESP32 equivalent of an analogWrite of an Arduino Uno/Nano, the function is used to set the PWM sign...
This Arduino Nano uses the stored MPPT values and for the particular insolation values generates the appropriate duty ratio by adjusting the sine amplitude by implementing sine pulse width modulation. 4.12 Incremental conductance MPPT The InC strategy depends on the way that the derivative of the ...
