This week, we worked on synthesizing the oscillators on the FPGA to produce a real audio output signal. This required correctly driving the DAC and initializing I2C communication with it. Ultimately, we were successful in driving the DAC using our previously developed oscillators. However, we noticed some issues with the periodicity of certain waveforms, as well as with the sine wave lookup table (LUT).
While working on fixing the oscillators and synthesizing a filter onto the FPGA, I encountered an issue accessing my account on the HH machines. Whenever I try to log in, I am redirected back to the username page. This has prevented me from synthesizing additional modules on the FPGA and continuing my work.
The next steps are to determine why I cannot access my account on the HH machines and then resume synthesizing modules such as filters and envelopes so we can move on to implementing effects.
