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: hệ thống Voltage
- Vf: Forward voltage của Flash LED cho Icc hiện tại
- VCE: Collection Emitter voltage, điển hình: 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 Mạch tham chiếu
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
Tậptage 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
Cái gì?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

For CAM1 Interface
dtoverlay=imx296, cam1
For CAM0 Interface
dtoverlay=imx296, cam0
Change camera_auto_detect=1 to camera_auto_detect=0

Chế độ kích hoạt bên ngoài
4.1 Mô tả
- 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
sudo nano /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
4.5 libcamera Tool
To make two cameras work in free running mode
ví dụamplê:

4.6 Trigger Tool
This tool can enable imx296 trigger mode individually.
./imx296_trigger [i2c bus] [on/off]

camera1 i2c bus =4
camera0 i2c bus =6
on=1 off=0
Examplê:
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

4.7 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

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 examplê:
i2cget -y 4 0x51 0x00
5.4: Write EEPROM and read the content
i2cset -y 4 0x51 0x00 0xaa
i2cget -y 4 0x51 0x00
