+BMX280 for ESP-IDF
+==================
+BMX280 is a basic I2C based driver for ESP32 devices licensed mostly under MIT.
+(See caption "License" for details.)
+
+Usage
+-----
+Clone this repository or add it as a submodule into your components directory.
+Add the module as a requirement to your main module, or other modules.
+
+Example Code
+------------
+```c
+#include "esp_log.h"
+#include "bmx280.h"
+
+void app_main(void)
+{
+    // Entry Point
+    //ESP_ERROR_CHECK(nvs_flash_init());
+    i2c_config_t i2c_cfg = {
+        .mode = I2C_MODE_MASTER,
+        .sda_io_num = GPIO_NUM_17,
+        .scl_io_num = GPIO_NUM_16,
+        .sda_pullup_en = false,
+        .scl_pullup_en = false,
+
+        .master = {
+            .clk_speed = 100000
+        }
+    };
+
+    ESP_ERROR_CHECK(i2c_param_config(I2C_NUM_0, &i2c_cfg));
+    ESP_ERROR_CHECK(i2c_driver_install(I2C_NUM_0, I2C_MODE_MASTER, 0, 0, 0));
+
+    bmx280_t* bmx280 = bmx280_create(I2C_NUM_0);
+
+    if (!bmx280) { 
+        ESP_LOGE("test", "Could not create bmx280 driver.");
+        return;
+    }
+
+    ESP_ERROR_CHECK(bmx280_init(bmx280));
+
+    bmx280_config_t bmx_cfg = BMX280_DEFAULT_CONFIG;
+    ESP_ERROR_CHECK(bmx280_configure(bmx280, &bmx_cfg));
+
+    while (1)
+    {
+        ESP_ERROR_CHECK(bmx280_setMode(bmx280, BMX280_MODE_FORCE));
+        do {
+            vTaskDelay(pdMS_TO_TICKS(1));
+        } while(bmx280_isSampling(bmx280));
+
+        float temp = 0, pres = 0, hum = 0;
+        ESP_ERROR_CHECK(bmx280_readoutFloat(bmx280, &temp, &pres, &hum));
+
+        ESP_LOGI("test", "Read Values: temp = %f, pres = %f, hum = %f", temp, pres, hum);
+    }
+}

+
+License
+-------
+This repository contains a lot of code I have written which is licensed under
+MIT, however there are sections modified from the BME280 datasheet which is
+unclearly licensed.
+
+The unclearly licensed section is clearly marked with two comments. Any code
+between `// HERE BE DRAGONS` and `// END OF DRAGONS` contains modified versions
+of the Bosch Sensortec code.
+
+Please take note of this in production.
