Stephen wrote an amazing in-depth blog post about the entire journey, including multiple failed attempts, designing custom PCBs, writing PIO assembly for the RP2040, implementing the GUD (Generic USB Display) protocol, and eventually landing on an STM32H750-based solution with precision DACs. I highly recommend reading it.，推荐阅读91视频获取更多信息

The implementation of this doesn’t really make any of this clearer, but there were a few handy tricks I was able to use while working through it. One of them was that I didn’t need to record anywhere whether we were pushing the button in or releasing it; we could deduce that from the last value we wrote in step 4. Another was in step 6; the N*8 term has a maximum value of 200, which means that we can put that result in an index register and do all our copying by indexing from a base of $2008 or $2009 as needed. No explicit pointers were necessary at all.
