• Bitnetmcu CNN implementation (cpldcpu.github.io):

  #cpldcpu got 99.5% MNIST accuracy with variable quantization and depthwise separable convolution on a CH32V002, a newer, smaller #RISC-V #CH32V003 with multiplier #hardware. #microcontrollers #electronics #hardware #neural-networks #toread

• Findings (github.com):

  By #cpldcpu. I don’t think I’ve ever seen such a deep dive into the #WS2812 addressable LED #electronics #hardware before. The key finding is that the Lite-On LTST-G563 doesn’t do any signal regeneration and will thus work very poorly in long strings.
