规格及使用方法

1

DC电源输入

DC 12V 3A. Please use the matched power adapter.
 DC port size: 5.5-2.1MM

2

HDMI 输入

HDMI 输入，最高支持4K 60HZ。

sudo systemctl disable SophonHDMI

reboot

sudo insmod /mnt/system/ko/v4l2_lt6911.ko

cd /opt/sophon/sophon-soc-libisp_1.0.0/bin/

./isp_tool_daemon

The current demo only supports 4K60. Modify the firmware for other resolutions.

3

Recovery按键

For USB firmware upgrade.

4

HDMI 输出

Supports up to 4K 60HZ.

5-6

以太网

1000M x2
 ETH1: Static IP; ETH0: Dynamic IP

7-8-9

USB 口

USB1: USB3.0 OTG port for firmware upgrade (TF card upgrade recommended).
 USB2 & USB3: USB3.0 HOST ports.

10

串口、GPIO口

RS485 – ttyS1, maximum baud rate 115200bps
 RS232 – ttyS3, maximum baud rate 115200bps
 Test with the supporting UART script.

Max load: 1A. Wire length shall not exceed 1M.

GPIO-IN

Low level or floating: CPU reads "1".
 High level (3.3-12V): CPU reads "0".

GPIO IN1：

echo 338 > /sys/class/gpio/export

echo in > /sys/class/gpio/gpio338/direction

cat /sys/class/gpio/gpio338/value

GPIO IN2：

echo 339 > /sys/class/gpio/export

echo in > /sys/class/gpio/gpio339/direction

cat /sys/class/gpio/gpio339/value

GPIO-OUT

CPU outputs "1": port outputs 3.3V.
 CPU outputs "0": port outputs 0V.

GPIO output is open-drain with 3.3V@10K pull-up. It can control 5V-12V devices (external pull-up required).

GPIO OUT1：

echo 335 > /sys/class/gpio/export

echo out > /sys/class/gpio/gpio335/direction 

echo 0 > /sys/class/gpio/gpio335/value

echo 1 > /sys/class/gpio/gpio335/value

GPIO OUT2 ：

echo 334 > /sys/class/gpio/export

echo out > /sys/class/gpio/gpio334/direction 

echo 0 > /sys/class/gpio/gpio334/value

echo 1 > /sys/class/gpio/gpio334/value
