海思Hi3516A（3）圖像sensor驅(qū)動(dòng)開(kāi)發(fā)

發(fā)布時(shí)間：2020-07-17 21:15:23 來(lái)源：網(wǎng)絡(luò) 閱讀：26028 作者：shugenyin 欄目：編程語(yǔ)言

1. 設(shè)備驅(qū)動(dòng)加載及系統(tǒng)配置

關(guān)于sensor的開(kāi)發(fā)環(huán)境、MPP的工作原理、ISP簡(jiǎn)介等可參考shugenyin的博客——海思Hi3518EV200。

cd ko
./load3516a -a -sensor sc3035 -osmem 64

在load腳本中添加sensor的相關(guān)配置，這里使用smartsens的SC3035-M的360萬(wàn)像素CMOS sensor。

{
	case $SNS_TYPE in
		sc3035)
			himm 0x200f0050 0x2;                # i2c0_scl
			himm 0x200f0054 0x2;                # i2c0_sda

			himm 0x2003002c 0xB0007             # sensolsr unreset, clk 27MHz, VI 250MHz

			echo "xxxx Invalid sensor type $SNS_TYPE xxxx"
			report_error

}


2. sensor的庫(kù)文件生成(.so)

sensor的庫(kù)文件需要在Linux服務(wù)器中的SDK包中編譯得到，將生成的.so文件放到SDK包中的stream軟件包中的Hi3516A_Stream_xxx/libs目錄下。

3. 修改stream軟件包的.ini文件

sc3035_3m_4lan.ini文件在Hi3516A_Stream_xxx/configs目錄下，改文件主要指定.so文件的位置、輸入視頻的接口(LVDS/MIPI/DVP)、視頻格式（分辨率、同步方式、目標(biāo)幀率等）等系統(tǒng)配置。

4. 運(yùn)行stream軟件

運(yùn)行stream軟件包中的HiIspTool.sh腳本，通過(guò)以太網(wǎng)卡與上位機(jī)的PQTools建立通信。

cd Hi3516A_Stream_V1.0.5.0
./HiIspTools.sh -a -p sc3035_3m_4lan.ini

ittb_control進(jìn)程是基于TCP的服務(wù)端，負(fù)責(zé)控制信號(hào)的傳輸。

ittb_stream進(jìn)程也是基于TCP的服務(wù)端，負(fù)責(zé)播放H.265或YUV視頻流。


5. 運(yùn)行PQ Tools

雙擊PQ Tools圖片，彈出如下對(duì)話框，設(shè)置IP地址。
