[0079] In the third embodiment, the present invention provides an inkjet printing system based on an ARM+FPGA architecture. The system realizes high-precision inkjet printing by collecting raster signals and subdividing the raster signals using a predictive subdivision method. , the system includes:
[0080] 1) Grating signal input filtering interface circuit: including Schmitt trigger and digital delay filter, used to suppress the noise mixed into the quadrature signal. After the quadrature signal passes through the Schmitt trigger, it must maintain 3 rising edges to pass through the digital filter, and the low-level noise less than 1V is filtered out. The remaining high-level, short-duration noise pulses are filtered out by a digital filter.
[0081] 2) Verilog-based QEP signal phase discrimination, counting, latching and other functional modules;
[0082] 3) Realization of Kalman filter based on Verilog: In general applications, the Kalman filter is usually implemented by...
