Grove Triple Color #EInk Display 2.13'' with UART Interface ... Shall we connect this to #BL602? 🤔

This #EInk Display is powered by #STM32 F031 ... Interesting! 🤔

Arg this #EInk Display has no documented protocol ... Guess we'll have to read the Arduino code and talk UART to STM32 F031 🤔
Where's the #STM32 F031 (Cortex-M0) source code for this Grove #EInk Display? 🤔 I'm curious too

Let's do #BL602 UART with the Low Level HAL ... Without AliOS 😉

Grove #EInk Display runs on a cute UART protocol: "c" ... "a" ... "b" 😂
Am I supposed to feel Pain with Grove #EInk Display ... ? Getting worried 🤔

Today's "Catchphrase" is ... "#BL602 Pushing Pixels" 😂 ... Or maybe "BL602 Haunts My Dreams" 🤔

@lupyuen Everything looks just a little bloody :P
@brandon Haha yeah... Don't look too close 😉
Grove #EInk Display supports 3 colours: Black, White and Red ... Let's use Red to fill in as Grey ... Here's the #RustLang code for converting Greyscale PNG to Black and Red Bitmaps
