I have an analog camera with AV output and I was looking to interface it with raspberry pi 3.
I am looking forward for some guidance on the same.
Thanks.
its very simply provided you follow the steps meticulous. First of all you should have the 3.5mm 4 pole cable connect the pole with yellow white red RCA cables respectively as shown in the image.
It should be as specified in the picture to work.
Second, once we have connected the RCA cable to TV set,
see to that we follow the exact instructions given here in this link.

See to that hdmi_force_hotplug=1 is commented out. It is needed because you are bypassing the video output to RCA instead of HDMI. See to that the sdtv_mode=2, i.e. normal PAL, has been uncommented. Reboot and it is good to go...

I am looking to use a beagle bone black with codesys to read signals through the CANBUS.
I am following the instructions from codesys on how to install their software on the beaglebone. The first thing is to flash the BBB with the latest debian image. For this I am using Balena etcher, which says it has completed successfully. It has taken about 4GB on the SD card and I cannot view the files as they are in a partition, is this correct?
Following the usual intrustions like :https://beagleboard.org/getting-started#:~:text=The%20access%20point%20password%20defaults,8. doesn't make the 4 LED's light up in the pattern like I've seen on videos. And therefore the image hasn't flashed?
I started to follow the instructions : Unable to Flash eMMC from SD Card BeagleBone Black however when I use the line "sudo nano boot/uEnv.txt" I get the error "Directory 'boot' does not exist".
Does this mean there is an issue with the image? However, I have used more than one SD card and re flashed them etc.
Any help would be great!
I just bought new ESP8266 wifi module 5 days ago and looks like below:
Black colour
No Ai Thinker text
No Ai Cloud text
Cost : 7~10 $
I have tried many ways/websites/advices to make it works but I got nothing.
None AT command works
Flash new firmware keeps fail
Blue light blinking tutorial works
Official websites that I have go through it's step but doesn't work:
Instructables
Github
Stackoverflow
Espressive
Youtube
Thingspeak
Ubidots
I have start my dev on this esp since 4 days ago
Please help me 😣
The ESP8266-01 boards are not breadboard-direct friendly. You'll find it easiest to attach some female-male jumper cables on the appropriate pins.
To flash the chip, this is the pinout you'll need.
ESP01 (left) and FTDI (right)
CH_PD + VCC = 3.3V (aka VCC)
GND + GPIO0 = GND
RXD = TXD
TXD = RXD
I am using a 3.5'' TFT LCD Display with the Raspberry Pi 3 (and latest Raspbian Stretch). Can anyone please tell me how I can change the screen resolution (on the screen it says 480x320) of my Rasperry Pi.
I installed the screen like they described in this tutorial. But now I have an overflow (parts of the screen are out of the provided Screen-Size (eg. Dialogs, System settings dialog, ...). Changing the /boot/config.txt values to (as described here):
overscan_left=24
overscan_right=24
overscan_top=10
overscan_bottom=24
framebuffer_width=480
framebuffer_height=320
sdtv_mode=2
sdtv_aspect=2
did not helped. Any clues? Thank you.
Try by changing parameters this way in /boot/config.txt..
hdmi_drive=2
hdmi_group=2
hdmi_mode=16
overscan_left=20
overscan_right=12
overscan_top=10
overscan_bottom=10
I am trying to use Kinect 2 and SDK v2 for capturing Infrared Images/videos.
Kinect shows Depth and RGB images properly, But when i try to visualize Infrared Basics in Kinect for Window. It does not show any image, rather a black screen.
What is the reason for it. I reinstalled SDK v2, but still the same problem. In a similar post some one suggested that reinstall a newer version, which I did. But still the same problem. Can any one suggest any solution?
thanks
it is better to use "KinectConfigurationVerifierSetup" for test system requirements. and i suggest you that use Infrared Basic-WPF Samples in SDK Browser, also you could use that sample code and install them to your computer. if still infrared data source not show, you could test Kinect on other computer
I fixed my problem by updating GPU Driver. It has a conflict/bug/error with older version. However Nvidia removed it. And if one install new driver, it start showing infrared images.
Attention for your graphics card setting, Maybe changing your computer to auto or Inter HD Graphics will work.
Hi~ I am trying to calibrate my depth camera with my digital camera.. but I meet some problem using the RGBDKinectCapture...
1、why the calibrate correspondence cannot show the RGB view from my digital camera?? (canon EOS 600D)
I have set it the live view mode..
2、it cannot recognize my kinect(1414) on Win7 By the example application (download from the RGBToolKit.com),
and I cannot run the source on Windows,just say the error 'enable_if' also mean the std::tr1::enable_if...
3、What is the methods of taking live preview for （all) the HD camera in RGBToolKit ??
is it without the SDK of camera??
which methods it based on??
which class? and I want to debug it...
I'm so sorry ... I see now...
1、the RGBDToolkit doesnot display the live preview of the HD camera.... it just load its video....
２、I cannot run the example on windows because it run with the different sdk for kinect ...（the source has give the sdk..）
