using beaglexM as video server

Most project is working on ubuntu, like this one:
http://www.hackourlife.com/diy-webcam-server-or-home-security-monitoring-setup-using-beagleboard-xm-running-ubuntu/

To do so, first thing is to make a ubuntu on beagleboard:
http://elinux.org/BeagleBoardUbuntu

down load the image, the trick is here:

Install image:
Quick install script for "board"
sudo ./setup_sdcard.sh --mmc /dev/sdX --uboot board
"board" options:
  • BeagleBoard Ax/Bx/Cx/Dx - beagle
  • BeagleBoard xM - beagle_xm
  • BeagleBone/Black - bone
So for the BeagleBoard xM:
sudo ./setup_sdcard.sh --mmc /dev/sdX --uboot beagle_xm

after boot up with ubuntu, we could log in as ubuntu with password:temppwd
first thing t try is sudo apt-get update
then we  Install motion by doing:
sudo apt-get install motion

when it's done, it should be like this, with no error


The headless Ubuntu server running on my BeagleBoard XM doesn’t allow access of /dev/video0 (webcam) without root permission, therefore I had to add my user name to group video by doing the following (I am assuming that you have already sshed in to your headless server or are sitting locally on your target machine):
sudo usermod -a -G video ubuntu



Now create a directory .motion in your home directory (i.e. /home/my_user_name):
mkdir .motion



this .motion is not visible with ls, but you can still cd .motion to go in to it.
the we will creat a motion.conf under this folder:
or we can make this file under PC and use fileZilla to transfer to xM in this folder. motion.conf should have these line:

daemon=on
norm=3
input=8
auto_brightness=on
framerate=15
height=288width=352
jpeg_filename=motion/%Y%m%d/%v-%H%M%S-%q
noise_tune=off
output_all=off
output_motion=off
output_normal=off
quality=75
snapshot_interval=0
target_dir=/home/my_user_name/capture
text_left=(c) Abhi
text_right=%d %b %Yn%k:%M:%S
threshold=500
v4l2_palette=6
videodevice=/dev/video0
webcam_localhost=off
webcam_maxrate=100
webcam_port=8080
webcam_quality=85


detail config could be read by typing this

sudo less /etc/motion/motion.conf


Now you launch motion by typing
motion
If all went well you would see the message
[0] Processing thread 0 – config file /home/abhish/.motion/motion.conf
[0] Motion 3.2.12 Started
[0] Motion going to daemon mode


the server is running, open a browser and point to the server. ex:my xM has IP=192.168.0
107, the server is 192.168.0.107:8080
should be able to see the cam running:

In fact, motion is more powerful than this, it could detect motion get jpeg...etc.

Heltec ESP32+OLED+Lora, hardware testing

圖片
you can easily find some good boards from china, but most of them lack of accurate document... Hrere is an example; https://hackaday.io/project/26991-esp32-board-wifi-lora-32 the board looks good with lora and a 128x64 OLED, but the IIC and reset connection is important, since pin can be muxing easily, so every board could be different. pinMode(16,OUTPUT);  digitalWrite(16, LOW); // set GPIO16 low to reset OLED  delay(50);  digitalWrite(16, HIGH); // while OLED is running, must set GPIO16 to high  and, if needed, edit your Wire.begin() to Wire.begin(4,15); (4 = SDA 15 SCL)  i tested it with the Adafruit SSD1306 and the Acrobotics SSD1306 Librarys  both work.  Display size is 128x64 There are discussions on these boards on TＴＮ as a LORA node..or maybee single ch gateway? Heltec has a git :  https://github.com/Heltec-Aaron-Lee And there is another copy call TTGO https://de.aliexpress.com/item/TTGO-LORA32-868-915-Mhz-S...

micro SD card for ESP32, on lolin32 with OLED and heltec 32 lora oled

圖片
I have purchased 2 micro SD card holder for my esp project. First I would like to test with heltec esp32 lora oled module. this module uses: sck=05 MISO=19 MOSI=27 SS(lora)=18, then I assigned 21 for sd SS and there is a lib in esp32-arduino, which use SS default at 5 I took the example and use SD.begin(21), but I alway get the error: entry 0x40078a9c Card Mount Failed But I do saw once that it read out the sd card type and volume. Not sure it's the issue of lora sd card swithing, or it just can't work. The other esp32 card I have is an wemos esp32 oled, it did not leave me too much pins, I need to find out how to connect sd to it. But I have wemos D1 mini esp8266 on hand, and connect it as:  * The WeMos Micro SD Shield uses:  * D5, D6, D7, D8, 3V3 and G  *  * The shield uses SPI bus pins:  * D5 = CLK  * D6 = MISO  * D7 = MOSI  * D8 = CS It's not working with the example in the arduino IDE 1.8.5, which m...

AIS0. understanding AIS NMEA 0183: How it's coded

For my boat tracking system, I found out that using AIS format seems to be a good idea, at least I don't have to worry about how to present boat data, since there are already plenty things for do this on mobile phone or PC. Here is what I read: http://catb.org/gpsd/AIVDM.html Looking into AIS NMEA0183, it has much more application then I think. Such as MOB device, epir, aid to navigation device...etc, all are included. it use the first few char to indicate the function: Table 1. AIS talker IDs !AB NMEA 4.0 Base AIS station !AD MMEA 4.0 Dependent AIS Base Station !AI Mobile AIS station !AN NMEA 4.0 Aid to Navigation AIS station !AR NMEA 4.0 AIS Receiving Station !AS NMEA 4.0 Limited Base Station !AT NMEA 4.0 AIS Transmitting Station !AX NMEA 4.0 Repeater AIS station !BS Base AIS station (deprecated in NMEA 4.0) !SA NMEA 4.0 Physical Shore AIS Station It can also be used between device on boat for message communication, AIVDO The...
