Hey, can I use this design for commercial applications?

The text describes a QFN and a QFN part designation (ML) but the renders and photos look like QFP. Can you clarify?

This is exactly what I have been looking for, how can I get this board?

Hi, thanks for this board, I think it will be very usefully for many project!

I'm considering building a couple of boards..
Do you have a BOM ready for the non-Altium users?

Also, looking at the gerber, it looks like it's a 6 layers board. Is it right? Do we really need 6 layers for this project or do you think it's doable on 4 layer with similar ? (or even 2?)

Best,
T.

Hi,
We have built a board and it seems to work ! For the moment I did some tests with the SOEM library and the device is recognized as a slave.

As I understand the LAN9252 have to be configured through ethercat, for that you give an DieBieSlave-IMU.esx and it has to be opened with ethercat-SDK in order to generate a binary. This binary can be sent to the LAN9252 with this eepromtool, for example. Am I right ?
Another point : I can't generate the binary file in ethercat-SDK with the free licence. Did you buy the licence?

Thanks

Hi,
Thanks a lot for this design !
I am building a DieBieSlave board and I encounter difficulties to know the implantation of each components.
I tried with Altium and Cadence to extract the names (L8,C1...) but I can't isolate the layer "name" for each side, it seems the names are on the same layer.
For the instant I wrote the name of each components one by one on a photo of the board but is fastidious and source of errors.

How did you do for mounting your board? Do you have the implantation scheme?

Hello,

There are some routing faults on decoupling capacitors. The power line track should go first throught the capacitor and the to the VDD pin.

If you can share your code source.I'm studying on a similar project
Thank you

Hi,
Now my device is reconized as a slave in twincat but is blocked in the INIT state, when I try to force the device to the next state "Pre-Op" I have this error : INIT INIT_ERR.

I flashed the stm32 and I can see the same issue. The code still blocked in middleSOESInit() waiting OP mode :
do{ ESC_read(ESCREG_DLSTATUS, (void *)&ESCvar.DLstatus, sizeof(ESCvar.DLstatus)); //ESCvar.DLstatus = etohs(ESCvar.DLstatus); } while ((ESCvar.DLstatus & 0x0001) == 0);

Nothing is connected on the GPIO, the board is connected alone.

The connection between the EEPROM seems right because is reconized as a slave in twincat.

Do you have an idea of the possible cause of this issue ? Thanks
