I2C IR-day/night mode
-
Hello, im seeking some clarification on using the I2C on VEYE-MIPI-IMX385 on the jetson nano. my main goal is to find the easiest way to use the day/night mode IR CUT and from what the wiki shows its very simple to use the i2c, but im confused about the pin layout. on IMX385 wiki J7 are the Auxiliary IIC and so i connect to the jetson pin 3 SDC and pin 5 SCL, but also on the wiki http://wiki.veye.cc/index.php/I2c_bus_number_and_video_node
it shows
1.2.3 Nano B01
i2c num 7 or 8
1.2.4 Nano A02, Nano 2GB
i2c bus number is 6.they are not I2C pins on the jestson nano, can i just check if this is correct.
-
i see my confusion now from the wiki that they are bus numbers
however i can not seem to find the i2c bus for the camera, everything should be connected correctly but command
i2cdetect -y -r 1is not finding anything even tho it is connect to bus 1
and i am now also confused on how to use the cmdsudo ./veye5_mipi_i2c.sh -w -f daynightmode -p1 [0,2]
please tell me how to do this
sorry for being noob. -
@rob77 said in I2C IR-day/night mode:
IMX385 wiki J7 are the Auxiliary IIC
Please do not use this IIC, the main 15pin FFC cable has an IIC bus already.i2cdetect -y -r 1
Do not use 1 here, use the correct i2c bus number corresponding to your board.
1.2.3 Nano B01
i2c num 7 or 8
1.2.4 Nano A02, Nano 2GB
i2c bus number is 6. -
@veye_xumm ah i see, i was mistaken thinking it used another I2C conection, cool i unpluged the Aux IIC and did a check, i have a nano B01 and checked the i2cdetect bus 7 and 8 and yep it found it connected, strangely bus 6 is also active even tho nothing is being used on it i think. that solves that.
my next problem is useing the day/night comand, im just not sure how to use it as veye_mipi_i2c.sh dosent do anything.
my goal is while the camera is on that i can switch between IR filter on and off easly. -

http://wiki.veye.cc/index.php/VEYE-MIPI-290/327_i2c/#daynightmode./veye_mipi_i2c.sh -w -f daynightmode -p1 0xFF or 0x FE -b 7 or 8
-
@veye_xumm thank you for that i tryed ./veye_mipi_i2c.sh -w -f daynightmode -p1 0xFE -b 7 and 8 to get the ir mode but it still dosent seem to work. i end up getting
bash: ./veye_mipi_i2c.sh: no such file or directory
their is probably a step im missing due to still being new to the nano. -
-
@veye_xumm i understood i needed to use those files from the wiki but what do i do with them? do they go in /boot/veyecam directory?
-
@rob77 no
-
@veye_xumm ok.
running the files just ends with errorno such file or directory. ive tryed running them in terminal and vim with no luck. there is clearly something im missing or not understanding, unlike the raspberry pi you have to enable./enable_i2c_vc.shbut on jetson nano it is already enabled meaning first steps are not required, so i continue with commands that should work but for some reason are not. is there another directory the files are ment to go in? or is there another way to control day/night mode? -
@rob77
Under linux, the following command means that you don't have this file in your current directory.
You need to go to the directory where this file is located and execute the command.
This is a common knowledge of linux.bash: ./veye_mipi_i2c.sh: no such file or directory -

Please try this.sudo apt install dos2unix dos2unix ./veye_mipi_i2c.sh -
@veye_xumm thanks that fixd the file into unix and i was able to open it. i then enter the day/night command
rob@rob-desktop:~/nvidia_jetson_veye_bsp/i2c_cmd/bin$ ./veye_mipi_i2c.sh -w -f daynightmode -p1 0xFE -b7 should be root!it says should be root? so i redo it as root superuser, but got file/directory error. i tryed other types of commands but getting same error.
rob@rob-desktop:~/nvidia_jetson_veye_bsp/i2c_cmd/bin$ sudo -i ./veye_mipi_i2c.sh -w -f daynightmode -p1 0xFE [sudo] password for rob: -bash: ./veye_mipi_i2c.sh: No such file or directory -
JUST fixed it
sudo -s want to say thank you for your help and patience with me, a person who has very little experience using linux. the camera is perfect for my project and i will be using it to learn more.

@rob77 You are welcome.
