Progress • Mostly debugging • PWM issues: Able to control PWM without GUI, but it didn’t work later • Looking at time lag between ASCII file input and DAC output • Appears to be a limiting threshold for updating information (~12 ms) • Reduced to 4 ms when print statements were removed • Connecting PWM and DAC output • Thinking of using a relay to switch between two voltages on a DAC, triggered by the PWM output from the PIC
Next steps • Today/weekend • Continue to debug GUI/PIC connection • Make circuit to connect PWM and DAC output • Continuously updating GUI • Next week • Anything of the above that isn’t finished • Testing with MXS (“should be in the mail [yesterday]”) • Once we solidify the system we want: PCB layout, components box design
