隨著工業物聯網(Industry Internet of Things, IIoT)的快速發展,在工業應用環境中需要采用越來越多的傳感器來檢測設備的運作狀況,這些傳感器可以采用兼具安全性與低功耗的新型藍牙低功耗(Bluetooth? Low Energy, BLE)微控制器(MCU),來提升傳感器的聯網能力與運作效率。本文將為您介紹安森美(onsemi)所推出的BLE微控制器,以了解其功能特性與應用領域。兼具低功耗與安全性的無線連接技術從用于聯系追蹤的信標到可追蹤的資產標簽,全球有數百萬臺聯網設備使用小型
通過上一節的學習相信都可以點亮WS2812了,我們這次來實現通過按鍵來控制WS2812的模式切換我這里簡單的寫了幾種模式通過原理圖可以看出來,開發板上的按鍵連接的是PC13引腳。好的,知道了按鍵的引腳,我們打開STM32CubeMX軟件來配置引腳,如圖所示。同時使能中斷。生成代碼,打開工程。在/* USER CODE BEGIN 4 *//* USER CODE END 4 */之間重寫中斷回調函數,代碼如下。void HAL_GPIO_EXTI_Rising_Callback(uint16_t
