【CW32模塊使用】TCS34725顏色識別傳感器

本模塊是基于AMS的TCS3472XFN彩色光數(shù)字轉(zhuǎn)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(yīng)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(yīng)，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12C接口通信。本設(shè)計基于同一個設(shè)計原理，提供2個不同造型設(shè)計(方形版本/雙孔版本)，提供用戶更多安裝尺寸和環(huán)境的選擇，其中雙孔版本布局了2個LED燈對于物體進行補光。

三移植過程

我們的目標是將例程移植至CW32F030C8T6開發(fā)板上【能夠識別顏色數(shù)據(jù)】。首先要獲取資料，查看數(shù)據(jù)手冊應(yīng)如何實現(xiàn)讀取數(shù)據(jù)，再移植至我們的工程。

3.1查看資料

I2C地址：

I2C 設(shè)備地址為 0X29

注意：0X29 這個設(shè)備地址是 7 位的，8 位設(shè)備地址需要向高位移一位變成0X52。

I2C寫時序：

首先主機會發(fā)送一個開始信號，然后將其 I2C 的 7 位地 址與寫操作位組合成8位的數(shù)據(jù)發(fā)送給從機， 從機接收到后會響應(yīng)一個應(yīng)答信號，主機此時將命令寄存器地址發(fā)送給從機，從機接收到發(fā)送響應(yīng)信號，此時主機發(fā)送命令寄存的值，從機回應(yīng)一個響應(yīng)信號，直到主機發(fā)送一個停止信號，此次 IIC 寫數(shù)據(jù)操作結(jié)束。

I2C讀時序：

首先主機會發(fā)送一個開始信號，然后將其 I2C 的 7 位地址與寫操作位組合成 8位的數(shù) 據(jù)發(fā)送給從機，從機接收到后會響應(yīng)一個應(yīng)答信號，主機此時將命令寄存器地址發(fā)送給從機， 從機接收到發(fā)送響應(yīng)信號，此時主機重新發(fā)送一個開始信號，并且將其 7 位地址和讀操作位 組合成 8 位的數(shù)據(jù)發(fā)送給從機，從機接收到信號后發(fā)送響應(yīng)信號，再將其寄存器中的值發(fā)送 給主機，主機端給予響應(yīng)信號，直到主機端發(fā)送停止信號，此次通信結(jié)束。

3.3移植至工程

移植步驟中的導入.c和.h文件與【CW32模塊使用】DHT11溫濕度傳感器相同，只是將.c和.h文件更改為bsp_tcs34725.c與bsp_tcs34725.h。這里不再過多講述，移植完成后面修改相關(guān)代碼。

在文件bsp_tcs34725.c中，編寫如下代碼。

四移植驗證

在自己工程中的main主函數(shù)中，編寫如下。

/* * Change Logs: * Date           Author       Notes * 2024-06-20     LCKFB-LP    first version */#include "board.h"#include "stdio.h"#include "bsp_uart.h"#include "bsp_tcs34725.h"
int32_t main(void){    board_init();        // 開發(fā)板初始化
    uart1_init(115200);        // 串口1波特率115200
    TCS34725_Init();    printf("startrn");    delay_ms(1000);    while(1)    {        TCS34725_GetRawData(&rgb);  //讀兩次，實際測試時發(fā)現(xiàn)讀到的顏色總是上一次的顏色        RGBtoHSL(&rgb,&hsl);        printf("R=%d G=%d B=%d C=%drn",rgb.r,rgb.g,rgb.b,rgb.c);        printf("H=%d S=%d L=%drn",hsl.h,hsl.s,hsl.l);
        printf("n");        delay_ms(1000);    }}

移植現(xiàn)象：輸出當前RGB值。
