VCE (السبت) | IF 10mA, Ic = 1mA | 0.1 | 0.2 | V |
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: مجلد النظامtage
- Vf: Forward voltage من Flash LED لـ Icc الحالي
- VCE: Collection Emitter voltagه، نموذجي: 0.1 فولت
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 الدائرة المرجعية
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
المجلدtage 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
واتtage 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

وضع التشغيل الخارجي
4.1 الوصف
- 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

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 exampعلى:
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 الوصف
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.
