Encoder not working

KunzGbR

Hi,

we've currently bought a set with an extended controller, motors and encoders from iflight (https://www.iflight-rc.com/index.php?route=product/product&product_id=252) through an german dealer.
Now I'm trying something desperate to set up the encoder.
The encoders are connected with the six pin cables and in the software the encoder type is set to AS5048A (SPI) with 1MHz.

If "skip autodetection" isn't set, the electronics already fall into a litany of peeping when switched on.
However, if it is set, the electronics starts but no values appear in the monitor, the encoders can not be calibrated and the read errors are counted up in the debug.

Do I overlook something or is the electronics broken?
I would exclude the encoders, because there are all three of them which I get no data.

I've never worked with encoders before and my dealer is unfortunately unwilling to help me.

Bet regards
Daniel

Hello,
First of all, try to check encoders connection, because SPI connection type requires connecting all 6 wires to each encoder.
And to check the encoders (page 10) as described here: https://www.basecamelectronics.com/files/SimpleBGC_32bit_Encoders.pdf

Hi Andrew,

as already said: The Encoders are connected with six pin cables and the type is set and there are also no values from the encoder in the monitor tab.

Hello,
Ok, but Debug tab can provide more info about connected encoders.

"read errors are counted up in the debug."
- Could you place here info from Debug tab?

Also, we need to know how did you connect connected encoders?
Because on screenshots from you link placed regular board, and you need to use these pins for connection:

Can you make a photo of connection and place link here?

Hi Andrew,

as mentioned in my first post, I've the Extended version, so there is a dedicated port for each encoder.
iFlight loves to change pics and products without changing the product id.
The new Link in their shop is
https://www.iflight-rc.com/index.php?route=product/product&path=25_240&product_id=331

A picture from the underside of the board would be a bit hard to make, since everything is build in to a copter.

Hier is the link to the debug outputs

Best regards

Another important thing, there are two types of AS5048 chips: https://media.digikey.com/pdf/Data Sheets/Austriamicrosystems PDFs/AS5048A,B.pdf
Types differ in available interfaces:
AS5048A - SPI + PWM
AS5048B - I2c + PWM
What type of chip do you have on the board?

Hello,
I found similar motor from Iflight with built-in encoder, and discovered there AS5048L
This is clone of AS5048A chip is compatible with our boards.
But sequence of pins in the connector is different from sequence of pins in our controller.
This photo with description will help you connect the encoder correctly: http://ybex.com/d/q3uhyb1tzgsda23jecy4hlfk7pbdyb244g6zxthv.html

hello dear Andrew

i have problem like similar discuss . i also have problem from iflight encoders and alexmos board , i bought controller board version extended . when i read your messages i see you put the link address for photo : http://ybex.com/d/q3uhyb1tzgsda23jecy4hlfk7pbdyb244g6zxthv.html .

when i tried to open this photo doesn't work . could you please let me use the conection diagram of iflight extended board with AS5048L ??

Howdy, Stranger!
