Altera DE2 read input from a weight sensor's HX711 ADC

I would think you could completely skip using the Arduino and connect the HX711 directly to your DE2 board via the latter GPIO pins, making

sure that the DE2 and HX711 are using the same voltage level. Then program the Verilog in the Cyclone FPGA to calibrate and read the HX711,

perform the needed computations in Verilog, and display the output on the 7 segment display of the DE2. The datasheet for the HX711 shows

that it is a simple GPIO serial interface. You would need one or more load cells, in addition to the HX711, to make a complete system.

I would ask somebody locally to help you out, like a graduate teaching assistant, a fellow student, or a professor. Most graduate students

are happy to help other students.
