AT32 MCU USB HID應用,實現無縫連接「芯」體驗

2022-07-22

傳統設備數據傳送仰賴有線USB將資訊傳輸至主機,經常造成多條線材擺放凌亂、佈線空間及操控範圍受限等問題。基於科技革新速度不斷加快、推陳出新,IoT概念普及化,多數設備已由有線逐漸轉變為無線。

雅特力超值型AT32F415與無線型AT32WB415系列採用強大的32-bit ARM®Cortex®-M4為內核,在SoC單晶片系統上,整合多種通訊介面,如USB OTG、UART、SPI、I2C、SDIO等,搭配RF射頻進行資訊傳輸,實現USB HID無線傳輸功能,無須額外安裝驅動程式,即可幫助用戶快速完成資訊傳送和保持文件完整性。本文以客戶實際應用案例「AT32F415/AT32WB415系列MCU導入血壓計連接USB HID應用為例」。

AT32 MCU提供一個高精度、高性價比的血壓計應用解決方案。當血壓計測量脈搏率、收縮壓和舒張壓時,壓力感測器精確檢測到電流值及血壓強度訊號強度,如下圖所示。

導入AT32 MCU搭配RF射頻實現無線傳輸

 

AT32F415 / AT32WB415系列連接USB HID應用方案特點:

1.採用ARM®Cortex®-M4內核,主頻高達150MHz,內建大容量256KB Flash和32KB SRAM,並提供軟體開發工具,以利進行產品系統校正、更新和儲存使用者資訊。
2.支援UART、SPI、I2C、SDIO、USB OTG、CAN多種通訊界面,同時搭配RF無線射頻元件,支援藍牙無線傳輸功能(適用AT32WB415系列方案二),實現智能應用與產品功能加值。

AT32F415 / AT32WB415系列導入血壓計產品附加優勢:

1.支援12位高精度ADC及CMP,從壓力傳感器採集訊號中分辨壓脈帶和脈搏波訊號,精準提取脈搏波訊號,經濾波電路後,透過A/D轉換電路,輸出至CPU,無須添加額外元件,大幅降低開發成本和縮短量產時程。
2.支援高速GPIO/SPI驅動LCD顯示屏,流暢顯示血壓量測讀值狀態。
3.支援藍牙2.4GHz頻段,Rx靈敏度可達到-97dBm,Tx值介於-20dBm~+4dBm之間,有效範圍傳輸超過30m,資料傳輸最快可達到2Mbps,實現無線傳輸低延遲(適用AT32WB415系列方案二)。
