2.4 Flash Strobe Pins(J2)
2.4.1 參考電路
板載TLP281光耦隔離，注意最大集電極電流為50mA。

So, if the current required to drive the Flash LED is no more than 50mA
The value of series resistor: R1 = ( VCC- Vf – VCE ) / If
- VCC：系統卷tage
- Vf: Forward voltagFlash LED 的 e 電流 Icc
- VCE: Collection Emitter voltage、典型值：0.1V
If the current required to drive the flash exceeds 50mA,
- then it is required to drive it with the help of LED driver circuit, and LED driver circuit can be controlled by using the strobe output pin.
2.5 External TRIG Pins(J3)
2.5.1 參考電路
The calculations done here are based on 12VDC. Please do follow these calculations for other voltages like 24VDC.
Let’s take the current through IR LED I_{f} = 20mA
卷tage drop across the IR LED = 1.25V
The value of Resistor R1 = (Vcc-Vi)/If = (12-1.25)/0.02 = 537.5 Ω Wattage of resistor R 1 >l 2 ^ * R 1 =0.02^ 2* 537.5 = 0.215W
笏tage of the resistor R1 selected should be greater than 0.215W.
And there is a resistor on board (R * 4 = 200Omega) So the R_add = R1-R4 = 537.5 – 200 = 337.50

3.1 Modify config.txt
須藤奈米 /boot/firmware/config.txt
older os it should be sudo nano /boot/ config.txt
3.2 Add dtoverlay
For CAM1 Interface
dtoverlay=imx296, cam1
For CAM0 Interface
dtoverlay=imx296, cam0
Change camera_auto_detect=1 to camera_auto_detect=0
節省 file 並重新啟動。

外部觸發模式
4.1 說明
- The Global Shutter (GS) camera can be triggered externally by pulsing the external trigger (denoted on the board as XTR （Trig+）,GND(Trig-)) connection on the board.
Multiple cameras can be connected to the same pulse, allowing for an alternative way to synchronize two cameras. - The exposure time is equal to the low pulse-width time plus an additional 14.26us. i.e. a low pulse of 10000us leads to an exposure time of 10014.26us. Framerate is directly controlled by how often you pulse the pin. A PWM frequency of 30Hz will lead to a framerate of 30 frames per second.
4.2 Download source from our GitHub
We use raspberry pi5 as example, showing dual Camera in free working: sudo git clone https://github.com/INNO-MAKER/cam-imx296raw-trigger.gitcd cam-imx296raw-trigger sudo chmod -R a+rwx *
4.3 Setting config.txt
須藤奈米 /boot/firmware/config.txt
Add below content to last line follow [all]
dtoverlay=imx296,always-on,cam0
dtoverlay=imx296,always-on,cam1
4.4 Timeout Setting
sudo cp /usr/share/libcamera/pipeline/rpi/pisp/example.yaml timeout.yaml
Edit timeout.yaml by sudo nano timeout.yaml
delete the # (comment) from the “camera_timeout_value_ms”: line, and change the number from 0 to 60000,
Then run below command
export LIBCAMERA_RPI_CONFIG_FILE=timeout.yaml

4.6 Trigger Tool
This tool can enable imx296 trigger mode individually.
./imx296_trigger [i2c bus] [on/off]
Note: on pi5
camera1 i2c bus =4
camera0 i2c bus =6
on=1 off=0

camera 1 trigger on:
./imx296_trigger 4 1
camera 1 trigger off:
./imx296_trigger 4 0
camera 0 trigger on:
./imx296_trigger 6 1
camera 0 trigger off:
./imx296_trigger 6 0
4.6 Trigger Pins Wire
Follow Chapter 2.5
4.7 Trigger Signal
We use Raspberry PI5 PIN23,GND GPIO as trigger signal and send signal by below script, Script code is as below, save it to .sh file.
while true;do
gpioset gpiochip0 23=1
睡覺 1.9999
gpioset gpiochip0 23=0
睡覺 0.0033
完畢
Open another terminal window to run the script
On Board EEPROM
InnoMaker provide on board EEPROM, TYPE: FT24C08A(1KBYTE)
5.1 Operation env:
Hardware type: rpi5 ARCH64 OS , I2c bus on CSI : 4
5.2: Detect EEPROM on i2c bus:
i2cdetect-y 4
There should be 4 devices with address 0x50 0x51 0x52 0x53 detected.
Each device have 256 byte content.
5.3: Read EEPROM content
Take device address 0x51 sub address 0x00 as a examp樂：
i2cget -y 4 0x51 0x00
5.4: Write EEPROM and read the content
i2cset -y 4 0x51 0x00 0xaa
i2cget -y 4 0x51 0x00

6.2 說明
IMX296 official driver that provide by RPI default kernel not enable strobe by default.
Imx296 can output strobe while work in normal or fast trigger mode, We can enable strobe by i2c tools.
- Imx296 I2c address: 0x1a
- Pi5 csi1 i2c bus address : i2c-4
Note: strobe setting must be done while camera stream is off.
