5. IPC Application
In the IPC version, the rkipc service starts automatically after system boot. Before testing other functions, stop the rkipc service first.
1killall rkipc
1rkipc &
5.1 Serial Terminal
Connect the board and PC with USB Serial cable, then power on, the terminal will output boot information. The default baudrate is 1500000.
5.2 Display(MIPI)
In the IPC version, the system does not display a desktop by default after startup. If two cameras are connected before power-on, the system will automatically start the camera preview after booting. The display output shows the preview image from.
5.3 USB
5.3.1 USB OTG
The USB OTG port of Idea1126B-P is configured as host mode by default at startup.
echo device > /sys/kernel/debug/usb/21500000.usb/mode
usbdevice start
echo host > /sys/kernel/debug/usb/21500000.usb/mode
5.3.2 USB Host
The USB2.0 Host can connect peripherals such as mouse, keyboards, and flash drives.
When a USB flash drive is inserted, the system will automatically mount it.

5.9 PIR
The PIR sensor is used to detect human motion by sensing changes in infrared radiation.
Test the PIR sensor:
1pir_test.sh
When human motion is detected, the output is 1. When no motion is detected, the output is 0.
# pir_test.sh

5.10 Photoresistor
The photoresistor is used to detect ambient light intensity.
Read the raw ADC value.
1cat /sys/bus/iio/devices/iio\:device0/in_voltage1_raw
# cat /sys/bus/iio/devices/iio\:device0/in_voltage1_raw

The output value changes with the ambient light intensity.
5.11 Relay
The relay has three terminals: NO, NC, and COM. By default, the relay is energized after power-on, and NO is connected to COM.
Release the relay:
1echo 1 > /sys/class/leds/raley_power/brightness
After execution, the relay is released, and NC is connected to COM.
To energize the relay again:
1echo 0 > /sys/class/leds/raley_power/brightness
After execution, NO is connected to COM again.
5.12 RF315(Deferred)
Deferred due to ongoing software debugging.
5.13 Wiegand
The Wiegand interface is commonly used for access control devices, such as card readers and keypads.
The board provides two Wiegand interfaces: Wieg_OUT and Wieg_IN. A loopback test can be performed by connecting Wieg_OUT to Wieg_IN.
❶ Connect the Wiegand pins.
❷ Open a terminal through the serial port, run the Wiegand output test program.
1wg_out_test
# wg_out_test
####Setup Wiegand output 26bit or 34bit.####
[1] Wiegand output 26bit
[2] Wiegand output 34bit
Select: 1
Enter HID (0-255):
❸ Open another terminal through ADB and run the Wiegand input test program.
1wg_input_test
❹ After entering the HID and PID values in wg_out_test, check whether the HID and PID received by wg_input_test are consistent with the sent values.
In this example, HID=0x64 and PID=0x03e8 correspond to HID=100 and PID=1000, so the Wiegand input/output test is successful.
- Parameter Description:
The following uses the 26-bit Wiegand data HID: 6f PID: 8b5c Raw=0x2df16b8 as an example to describe the meaning of each parameter.
Wiegand 26bit: HID=0x64 PID=0x03E8 Raw=0x02C807D1
