Timing problems in `release` mode #34

Open kunerd opened 6 years ago

kunerd commented 6 years ago

On fast hardware without OS, e.g. f3 discovery, stm32, the initialization flow doesn't work reliable.

  1. 4-bit mode initialization timing needs to be re-factored
  2. write operation probably needs some better timing, too
