Hello All: First of all, I hope that I am making myself clear to everyone. (NOOB here!)
I have a mill setup that is working with LinuxCNC on the mesa 7i43 with both X and y Drives currently. My goal is to implement a DRO readout feedback loop into the FPGA DE0-Nano-Soc with machinekit. I would like to make a type of DRO feedback servo loop with the FPGA in realtime using the FPGA as the counter decoder/resolver functions. After still trying to understand machinekit I am looking for advice to see if this would be the best way to approach this problem. I have magnetic slide digital readout with no usable output digital signals. But after probing inside the unit (Sony unit with magnetic slides) I can tap off a digital logic chip that creates a square wave in retaliation to another pin on the circuit card. Both signals would move in either direction of the magnetic slide. (basically covering which direction it is moving). The signals would be independent of the DRO itself. (for example, resetting the DRO to zero would not affect the signals into machinekit). I guess in essence this would be a replacement of the resolver function without all the math of signal processing? If I am correct? Also, having "limited" experience with Verilog HDL, I would be creating a HDL block that would either run separately or be included into the HostMot2 function block in the mkscofpga github Project. I understand the risks associated with a servo feed back loops such as this. Hence, why I am seeking advice. Your thoughts?? Thanks!
