Ok, this is not going to work, it is SSI but it does not have CS line to multiplex six sensors in same lines like the AEAT sensors!
It seems to be a big confusion here.
it seems that SPI interface from MegAuto is identical to SSI from AVAGO.
AVAGO vs MEGAUTO
Thanos, could you check if those SPI's could work with the AMC??
Ok I see, they name the simple shift registers as peripheral. Its not actually peripheral as you can not choose the register function as in normal SPI devices using bidirectional communication (MOSI, MISO).
So they are just using synchronous serial interface! (SSI). To clarify the usage of CS line is to latch the count register data to the output shift register so you can read them out by toggling the clock of the register. Its synchronous, as it spits out the bits according to the clock you feed it!
I cannot tell if its going to work exactly like the AEAT sensor though, there are other factors that are not mentioned anywhere in the datasheet like the exact timing of the bits, are they available on the rise or fall of the clock? What is the polarity of the bits? What is the phase shift of the transmission? I think the best way is to get one of these sensors on hand to capture their output with logic analyser to measure the timing myself and adapt the code to read those sensors as well. I see that they are 14bit (16,385 positions) that is good resolution for their price.

Oh yes please go for it!!!
The MegAuto catalogue is full of sensors with different attachments types. Once the interface adapted, we could finnaly have a real choice between many different attachment solutions.
sensor is working correctly because i can read its value from the screen of amc. 99 for 180 degrees, 0-99 the other 180 degrees. the amc setting for the default position is 50 so when it starts it should look for 50. but it doesn't. it turns to one direction if it reeds 99, and turns to the opposite direction if it reads anything else. speed is also constant. strange isn't it?
I found it. again it is my mistake. once i fried my first amc board then i got new ones. unfortunately i was using the old fried amc when doing the test. I tried it with the new one and it works like rock solid.
dureiken: Hi there, it's really quiet here someone could help me for my 6 dof project ? thanks a lot

tronicgr: dureiken Hi, Open a thread and I'll try my best to help. A little busy with Kickstarter details at the moment but I'll see what I can do.

fimmy: How's the firmware going?

tronicgr: @fimmy I had to put it on hold to finalize the manufacturing of the new kickstarter controllers. I tested parts of it to ensure compliance with the new features and looks good so far. I'll get back to it soon for integration.

Theuns: Very nice design.I'm also busy with mine and changing it also to Linear Actuators with 220v Servo motors.I'm waiting for my new controllers from Thanos. If I may ask Do you have any Sketchup files of your design and willing to share it I Thanks Theuns

atayeu: Hey everyone! I'm reading up and gathering all of the intel I can find for my first motion platform. this is by far best information for creating one.

tmcnam: I must be crazy but I still can't find the blueprints to the platform by GA-Dawg. Any help would be appreciated. Thanks guys.

Trip Rodriguez: Sorry tmcnam, the shoutbox doesn't get much attention. Did you find the blueprints? They are at the VERY bottom of the extremely long first post. It says "attachments: 6DOF.zip
