Everybody here is building the MintyMp3, but... How do I learn to design such a system??? I want to know how to design a hardware system like this or simpler.
I would like to know:
- Where to start?
- How do I know what passives I need in each part?
- How do I put together an MCU, mp3 codec, DAC, memory, power supply, rest of components such that the system works?
I already know:
- Overall components knowledge (mcu, mp3 codec, DAC, memory...)
- PCB schematic entry, layout, DFM, soldering
- mcu programming
