GPIO 使用方法 (GPIO Operating Method)

The RK3576 bank/bit notation for GPIOs must be formed as "GPIO<GPI￾O_bank>_<gpio_bit>".

The numeric value of GPIO is calculated as follows: 32 x (gpio_bank) + gpio_bit

gpio_bit: A0A7 0-7 B0B7 8-15 C0C7 16-23 D0D7 24-31

E.g. GPIO0_B5 becomes 13

| GPIO Number | GPIO formed | Numeric Representation | | :--- | :--- | :--- | | GPIO0 | GPIO3_D0 | 120 (default used by CAM0_PWR) | | GPIO1 | GPIO3_C7 | 119 (default used by CAM1_PWR) | | GPIO2 | GPIO3_D6 | 126 (default used by CAM0_RST) | | GPIO3 | GPIO3_A4 | 100 (default used by CAM1_RST) | | GPIO4 | GPIO4_B0 | 136 | | GPIO5 | GPIO2_D6 | 94 | | GPIO6 | GPIO4_B1 | 137 | | GPIO7 | GPIO0_A2 | 2 | | GPIO8 | GPIO0_B0 | 8 | | GPIO9 | GPIO1_D2 | 58 | | GPIO10 | GPIO1_D3 | 59 | | GPIO11 | GPIO0_C4 | 20 | | GPIO12 | GPIO3_C5 | 117 | | GPIO13 | GPIO3_C6 | 118 |

The remaining GPIOs marked on the test board have been used as other functional pins and cannot be set as GPIOs. Export GPIO then you can use control GPIO from user space through sysfs.

GPIO4 and GPIO5 are taken as an example: Connect GPIO4 and GPIO5.

• Export GPIO4 and GPIO5.

# echo 136 > /sys/class/gpio/export
# echo 94 > /sys/class/gpio/export

• Set GPIO4 to output and GPIO5 to input.

# echo "out" > /sys/class/gpio/gpio136/direction
# echo "in" > /sys/class/gpio/gpio94/direction

• Change GPIO4 to 1 and read GPIO5 value.

# echo 1 > /sys/class/gpio/gpio136/value
# cat /sys/class/gpio/gpio94/value 
1

• Change GPIO4 to 0 and read GPIO5 value

# echo 0 > /sys/class/gpio/gpio136/value
# cat /sys/class/gpio/gpio94/value 
0

UART使用方法 (COM1-COM4)

User Debian/Linux UART/serial port access is through the tty-devices. The tty￾devices have different names depending on UART drivers for different boards. 

| Device Node | SOM-DB2510 COM Port Name | | :--- | :--- | | /dev/ttyFIQ0 | COM4(Debug) | | /dev/ttyS2 | COM2(RS232 2-wire) | | /dev/ttyS4 | COM1(RS232 4-wire) | | /dev/ttyS10 | COM3(RS232 4-wire) |

Send and Receive Data

Taking COM1 as receiver or sender (An external COM is required to do the sending or receiving).

For example, AOM-5841 is responsible for receiving and inputting instructions. The PC computer is connected via a cable and COM1. The PC computer uses the Putty serial port tool, opens the COM port, configures the baud rate to 115200, data bits to 8, stop bits to 1, parity to none, flow control to none, and sends "pass" to the serial port assistant. If no error, the external COM receiver will receive “pass”.

# #---- COM1 as receiver ----# #
# stty -F /dev/ttyS2 115200 cs8 -cstopb -parenb
# cat /dev/ttyS2 &

# #---- COM1 as sender ----# #
# stty -F /dev/ttyS2 115200 cs8 -cstopb -parenb
# echo pass > /dev/ttyS2
# #----If no error, the external COM receiver will receive “pass”---
-# #
pass

RTC

Set the system to the current time then set the RTC.

# date 021710452016 && hwclock -w && date
Wed Feb 17 10:45:00 UTC 2016
Wed Feb 17 10:45:01 UTC 2016

Set one incorrect time, then read RTC to verify.

# date 010100002000 && hwclock -r && date
Sat Jan 1 12:00:00 AM UTC 2000
2016-02-17 10:45:14.178208+00:00
Sat Jan 1 12:00:00 AM UTC 2000

Restore the RTC time to system time.

# hwclock -s && date
Wed Feb 17 10:45:30 AM UTC 2016

Watchdog

A Watchdog Timer (WDT) is a hardware circuit that can reset the computer system in case of a software fault.

AOM-5841 supports one external watchdog. The default value of timeout is 60 seconds, and it can be set from 1 second to 6527 seconds.

Check Watchdog Device

List watchdog device.

# ls /dev/watchdog
/dev/watchdog

Usage

Here are two ways to use watchdog:

1. Use “echo” command. Writing any character except the specific magic character 'V' will open the watchdog, and write once before the timeout (60 seconds by default) passes, otherwise the system will reboot.

# echo A > /dev/watchdog

Writing the specific magic character 'V' to stop the watchdog.cc

# echo V > /dev/watchdog

2. Write a program using “ioctl” See more details in [BSP]/kernel/Documentation/watchdog/watchdog-api.rst.

CAN

AOM-5841 has two CAN ports.

Use the “candump” and “cansend” tools directly to send and receive messages. The tools have been embedded into the system.

SOM-DB2510 CAN Pin define

Preparation:

• Connect CAN0's CAN_L (PIN2 DB9) to CAN1's CAN_L (PIN2 DB9).
• Connect CAN0's CAN_H (PIN7 DB9) to CAN1's CAN_H (PIN7 DB9).

Testing

Run the following command on DUT Terminal、ADB or Debug console:

can0 is receiver, can1 is sender

# /tools/test/adv/can/can_test.sh can0 can1

can1 is receiver, can0 is sender

# /tools/test/adv/can/can_test.sh can1 can0

Check Network Ports

Check network ports of can0 and can1: 

# ifconfig -a
… …
can0: flags=193<UP,RUNNING,NOARP> mtu 16
 unspec 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00

Configure

Use “ip” command to configure can port.

See details of the usage of “ip link”:

# ip link help
… …
ip link set { DEVICE | dev DEVICE | group DEVGROUP }
[ { up | down } ]
[ type TYPE ARGS ]
… …
# ip link help can
… …
ip link set DEVICE type can
[ bitrate BITRATE [ sample-point SAMPLE-POINT] ] |
[ dbitrate BITRATE [ dsample-point SAMPLE-POINT] ] |
[ fd { on | off } ]
… …

For example, set can0

“birate rate” to 1000000

“dbitrate rate” to 2000000

“fd” to on

# #---- For can0 ----# #
# ip link set can0 down
# ip link set can0 type can bitrate 1000000 dbitrate 2000000
fd on
# ip link set can0 up

Taking port 22 as an example, you can enter the following instructions to view information such as the resolution, pixel format, Field, Number of planes, Flags, Color space, Transfer Function, YCbCr/HSV Encoding, Quantization, Bytes per Line and Size Image.

# v4l2-ctl -d /dev/video22 --get-fmt-video
Format Video Capture Multiplanar:
        Width/Height      : 1920/1080
        Pixel Format      : 'NV12' (Y/UV 4:2:0)
        Field             : None
        Number of planes  : 1
        Flags             :
        Colorspace        : Default
        Transfer Function : Default
        YCbCr/HSV Encoding: Default
        Quantization      : Full Range
        Plane 0           :
           Bytes per Line : 1920
           Size Image     : 3110400

Set Resolution

Taking port 22 as an example, you can enter the following commands to set the resolution to 1920*1080.

# v4l2-ctl -d /dev/video22 --set-fmt
video=width=1920,height=1080,\
pixelformat='NV12'

Preview Camera

Taking port 22 as an example, you can set the preview of the camera video by using the following command.

# export DISPLAY=:0.0
# export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/aarch64
linux-gnu/gstreamer-1.0
#gst-launch-1.0 v4l2src device=/dev/video22 \
! video/x-raw,format=NV12,width=1920,height=1080,framer
ate=30/1 \
! xvimagesink

Camera Photography

Taking port 22 as an example, the following command can be used to take a camera photo, and the save address is picture.jpg in the current directory.

# gst-launch-1.0 v4l2src device=/dev/video22 num-buffers=1 \
! video/x-raw,format=NV12,width=1920,height=1080 ! jpegenc !
filesink location= picture.jpg
