一、前言
是基于AMS 的TCS3472XFN 彩色光數(shù)字轉換器為核心的顏色傳感器,傳感器提供紅色,綠色,藍色(RGB)和清晰光感應值的數(shù)字輸出。集成紅外阻擋濾光片可最大限度地減少入射光的紅外光譜成分,并可精確地進行顏色測量。具有高靈敏度,寬動態(tài)范圍和紅外阻隔濾波器。最小化IR 和UV 光譜分量效應,以產(chǎn)生準確的顏色測量。并且?guī)в协h(huán)境光強檢測和可屏蔽中斷。通過I2C 接口通信。本設計基于同一個設計原理,提供2 個不同造型設計(方形版本/雙孔版本)
產(chǎn)品參數(shù)
二、資料獲取
關注微信公眾號--星之援工作室 發(fā)送關鍵字(TCS34725)
自己重新寫了一遍控制部分,并添加了反饋效果演示
????
三、設備使用
接線
接線方式如下,可根據(jù)個人喜好進行引腳的切換
圖片演示
視頻演示
懸空會自動反饋光譜最大的值進行顯示
顏色識別
四、代碼編寫
main.c
實現(xiàn)函數(shù)調(diào)用
/*接線
星之援學習資料 顏色識別
VCC------------>供電
DIO------------>PB9
SCLK------------>PB8
LOAD------------>PB7
GND------------>接地
RGB
R ---- PC15
B ---- PC14
G ---- PC13
可以根據(jù)識別到的顏色值進行亮燈提示
