Un-bricking the CH32v003
Newbies with cool tech like me are prone to "bricking" chips which basically means you can't program the things anymore.
Different chips react differently in these circumstances. Once upon a time I invested in a High Voltage AVR Programmer for reviving ATTiny85 chips that I had unwittingly fried with poor code. And it worked a treat!
The CH32v003 peeps in their wisdom have fortunately included in their one-wire communication protocol the ability to reset and therefore un-brick a chip.
There's a little VCC dancing to make it happen, but...well, take a look...
