Power System

This is the power system used to power the Smart Medicine Cabinet

Code

Hello World

C/C++
Code to test the ESP32
#include <stdio.h>
#include "freertos/FreeRTOS.h"
#include "freertos/task.h"
#include "esp_system.h"
#include "esp_spi_flash.h"

//Function declarations
//void test_motors(void);
//void setupKeypad();



void app_main()
{
	//SETUP GPIOS TO MOTORS/KEYPAD


	//CALL TEST MOTORS BELOW
	//test motors();



	//THE FOLLOWING RUNS A "HI WOLF" Program

GPIO Skeleton

C/C++
Code for setting up the GPIO

#include <string.h>
#include <stdlib.h>
#include "freertos/FreeRTOS.h"
#include "freertos/task.h"
#include "freertos/queue.h"
#include "driver/gpio.h"

//Configure GPIO 2 as output
#define GPIO_OUTPUT_IO_0 	2
#define GPIO_OUTPUT_PIN_SEL  ((1ULL<<GPIO_OUTPUT_IO_0))// | (1ULL<<GPIO_OUTPUT_IO_1)) use this if you want to configure more than one

//Function dec
void setupGPIO(gpio_config_t);


void setupGPIO(gpio_config_t io_conf)
{

		 //SET ALL PINS THAT YOU NEED AS OUTPUT AND CONFIG
		 //set as output mode
		 io_conf.mode = GPIO_MODE_OUTPUT;
		 //bit mask of the pins that you want to set,e.g.GPIO18/19
		 io_conf.pin_bit_mask = GPIO_OUTPUT_PIN_SEL;	//this is the pin I selected
		 //disable pull-down mode
		 io_conf.pull_down_en = 0;
		 //disable pull-up mode
		 io_conf.pull_up_en = 0;
		 //configure GPIO with the given settings 	(Pass in the address of io_conf after all settings reset)
		 gpio_config(&io_conf);


		 //SET ALL PINS THAT I NEED AS INPUT AND CONFIG AGAIN:


}


void app_main(void)
{

	//Create an instance of io configuration and setupGPIO
	gpio_config_t io_conf;
	setupGPIO(io_conf);

	//Turns on and off
	int cnt = 0;
	    while(1) {
	        printf("cnt: %d\n", cnt++);
	        vTaskDelay(1000 / portTICK_RATE_MS);
	        gpio_set_level(GPIO_OUTPUT_IO_0, cnt % 2);
