I am planning an stm32 module. I’m keen to learn how to develop hardware for my own fun. I will never sell anything!
As a learning step for me I thought that building a drum module would be fun and achievable.
I will use Peaks/DMC code as a base.
I’d like it to be 3 (or possibly 4) channel. I’ll use a dac8554 or 8564 probably and use hardware examples from yarns and peaks. (Umming and ahhing about how much cv control of parameters to include and whether to use multiplexers)
I’ve started cutting and pasting circuit fragments into Eagle and got an idea of where I am going… (I’ve also successfully had a couple of simple boards fabbed in China as an experiment and learning step)
My question is: how do you guys prototype the hardware? If it was through hole, I’d breadboard it. With SMT do you just design a board, fab it and try it? Then repeat the process… or is there an easier way to prototype? (I’m pretty happy with the software development side, I think! But hardware is new to me)
I’d also like this to be some base hardware I can play with other ideas that would require more cv precision rather than just audio so may well go for the dac8564 as in Yarns…
I’m probably being a bit ambitious and it’ll fail but if you dont try, you dont learn and it seems achievable given my limited knowledge.
Thanks a lot…
