Ikea bekant #9

Closed 3bitru closed 5 years ago

3bitru commented 5 years ago

Hello

I see you have a deep understanding.

I purchased a table bekant on sale in Ikea, not working. Found the failed elements and replaced them.

Connected to the LIN bus. If I connect slaves one by one they respond PID 8. If I connect two slaves, PID 8 will still be recalled.

The markings on the boards 68002430 FW: 3.9 Rev.2 17 / 47L. Maybe they are the same?

If I connect one slave will he move?

gcormier commented 5 years ago

Are you not seeing any commands for PID 9 on the bus?

3bitru commented 5 years ago

Yes, I do not see the commands PID 9 on the bus. I assume that I do not have them in the slave firmware.

gcormier commented 5 years ago

I'm not sure I understand the problem you're having. Slave firmware? Do you have custom hardware in the motors?

3bitru commented 5 years ago

All hardware (firmware) is standard, but I do not see PID 9.

gcormier commented 5 years ago

I would suspect one of your motors or controllers is broken or not working in some way then.

3bitru commented 5 years ago

I looked carefully. And I discovered that there is 0x08 (D0: 54 D1: 3 D2: 0) and 0x09 (D0: 0 D1: 255 D2: 0)

gcormier commented 5 years ago

Okay that is good, at least both are responding.

I'm not sure on the status though. You'd have to capture from the start to see what's happening and you can compare it with Startup Preamble.logicdata. I'm not sure what the status 0 means, I haven't seen that before.

The first success of the engines rotate if you press the button down, but if you press the button up, they do not rotate.

3bitru commented 5 years ago

press the button down 0x17 (D0: 0 D1: 0 D2: 2)
0x08 (D0: 0 D1: 255 D2: 2)
0x09 (D0: 0 D1: 255 D2: 2) 0x18 (D0: 0 D1: 0 D2: 189)

Not press the button 0x17 (D0: 0 D1: 0 D2: 0)
0x08 (D0: 241 D1: 254 D2: 0) 0x09 (D0: 241 D1: 254 D2: 0) 0x18 (D0: 241 D1: 254 D2: 252)

press the button up 0x17 (D0: 0 D1: 0 D2: 2)
0x08 (D0: 241 D1: 254 D2: 2)
0x09 (D0: 241 D1: 254 D2: 2) 0x18 (D0: 241 D1: 254 D2: 188)

Perhaps the controller thinks the table is at the top?

gcormier commented 5 years ago

You are using the IKEA controller? Or megadesk?

3bitru commented 5 years ago

Ikea

3bitru commented 5 years ago

This was the initialization mode. I installed the engines in the supports. I lowered it all the way down, the overcurrent triggered. And it all worked!

3bitru commented 5 years ago

Now it works as you wrote in the file "Protocol. Txt"

3bitru commented 5 years ago

Apparently, calibration was needed.

gcormier commented 5 years ago

Interesting! Thanks for the feedback!
