+ | We made initial schematic in kicad. | ||

+ | Next define electric bla bla in pcm3168A component. Make sure that every pins are connected to something (mark unused as unused). Continue until electrical rule check is passed. | ||
+ | |||
+ | When this is done figure out how to make PCB. | ||

+ | We (re)started working with kicad to define the PCM and FPGA chips. | ||

+ | Today we decided that Verilog sucks and added vhd2vl to toolchain. | ||

+ | Next time we will implement shiftregister in vhdl. | ||

Today we got two FPGAs working together as a serial coupled shift register. (The working code has been committed to git.) | Today we got two FPGAs working together as a serial coupled shift register. (The working code has been committed to git.) |
