Schematic is basically what I posted here: https://dashcamtalk.com/forum/threads/triggering-xiaomi-yi-from-a-digital-line-arduino.13446/#post-190274 Just different pins on the attiny85 vs the arduino.

You don't need to use an attiny85 unless you want it to be smaller. I programmed my attiny85 using my arduino nano (do a search on the net for how to program it). The only change you need to make to the code is which pins to use.

Thanks @luckylz. I didn't realize the order and spacing mattered. Do you know which specific messages are picky? No @Droscy, that's not right! Good eye! But the script still works so maybe I don't need this line at all? I'll have to test when I get some time. Unfortunately not. The gamma...

I've now moved my circuit from a breadboard to a perfboard and switched out the arduino nano for an attiny85. I've attached a picture of the result. Components used: 1 attiny85 1 330 ohm resistor 1 green led 2 bss123 mosfets

Ahh. Well that makes sense. Does Yi Plus work for you if you don't use the loop?

If you have a loop that takes a picture every second you wouldn't be able to do anything else with the camera so I'm not sure why you are trying to combine it with the yi plus script.

I did something similar to the Bluetooth remote (because I didn't want to fry the camera). My posts are in this thread: https://dashcamtalk.com/forum/threads/triggering-xiaomi-yi-from-a-digital-line-arduino.13446/ The Yi works really great as a multirotor camera BTW and many people in the...

I used 2N3904 transistors because they were what I found lying around, not because I have any clue what I'm doing. I've attached a ghetto schematic I drew in paint and the arduino code I wrote.

My latest progress:

I'm trying to hack the bluetooth remote to be able to trigger mode and shutter from an Arduino. The bluetooth remote is glued shut and it was quite difficult to open up without completely mangling it. I found locations on the board where I could patch in some wires to trigger the two buttons...

@gente I haven't tested, but try these: {"msg_id":2,"type":"photo_size","param":"16M (4608x3456 4:3)"} {"msg_id":2,"type":"photo_size","param":"12M (4608x2592 16:9)"} @mach I know the blinking wifi led is annoying but I don't think there is any way around it. The wifi isn't actually on though...

@itzik 1. The led pattern is a list of on/off commands and you can make the pattern as long as you like. The interval is how long it stays at each command in the pattern before switching to the next. For example, pattern 0110, interval 100 would be off for 100ms, on for 200ms, then off for...

The wifi led does blink but wifi isn't actually on so it shouldn't consume more power. I haven't done a comparison of run time with/without yi_plus running though so I can't be 100% certain.

@Ghetto Oh good, I'm happy to hear that. I think you're the first one besides me to get it working! Let me know if you have any ideas for the program.

@itzik 1. Yes, turn on as normal. The program takes an extra couple seconds more than the normal boot up time before it is running. 2. You can set the LED behavior in the yi_plus.json file. The example config blinks the shutter LED differently for each mode. One blink for mode 1, 2 blinks for...

What does the date say in yi_plus.sh? It should say 2015-09-23 as I just uploaded the change today. If that's what you have then I'm not sure what the problem could be. You could upload the log file if you can telnet into your camera. It's located here: /tmp/yi_plus.log Copy it to your sd...

@Ghetto I uploaded a new version that hopefully fixes your issue. Try it out and let me know (the specific change is in yi_plus.sh). @gente It will be a lot of modes if you want every combination of metering, rotating, and lens rectification. Have you tried editing the yi_plus.json yourself?

I have just now uploaded a new version that seems to start up more consistently (the changes for this are in the yi_plus.sh file). I also removed the wifi LED behavior from the yi_plus.json config because it was just adding more confusion.

1. You can have as many modes as you want! 2. Yes, you should be able to copy the lines from my autoexec.ash to yours. You will also have to copy the yi_plus directory to your SD card. 3. You can set the LED behavior for each mode. If you don't set LED behavior it keeps the same as original. 4...

Sorry, I don't know anything about the uItron OS.
