Last week I wanted to finish the power supply section (only the 3.3v rails are done, need to add low noise 5V regulators too) and to get a solid plan for the front panel interface. I accomplished both of these, which technically puts me on schedule. The positive and negative 5V rails are used for the analog path (VCF and VCA both require split rails) and the 3.3V is for logic, FPGA, encoders, etc. We solidified the plan for front panel interface including number and function of rotary encoders. I ordered all the front panel stuff, including knobs, encoders, and quadrature to I2C PCBs. Each encoder will have a small PCB behind it to count the quadrature pulses and put all of them on the same I2C bus which we will be able to poll with the SoC.
Next week, I want to make significant progress in PCB layout. The schematic is becoming more firm and I can start to do actual layout soon. At a minimum, I would like to start the analog path layout next week.
