Can we run #BL602 #RustLang Firmware in Flash ROM instead of Cache Memory? Nope, this needs more work ... Same for #Mynewt Firmware. And the JTAG Debugger is mandatory for coding Rust Firmware on BL602.

Red Bean Soup and Cheesy Spuds ... Yep both are undercooked 🤔

Now migrating 40 articles from Medium to GitHub Pages ... Not so hard, just tedious and repetitive 🤔

Starting the day ... With an environmentally friendly ad 😂

Thanks Medium for blocking all my educational articles ... Time to move out anyway 😉

We'll port the #LoRa SX1276 Driver from #Mynewt OS to #BL602 IoT SDK ... Because the GPIO and SPI Hardware Abstraction Layers are quite similar

Let's connect #PineCone #BL602 @PINE64 to #LoRa RF96 ... Always connect Antenna before Power! ⚡... Bought from Tindie

Grove #EInk Display has Zero Shades Of Grey ... But we created one for #BL602 anyway 😉

Here's how #BL602 sends an image to Grove #EInk Display over #UART

If I ever write "The #RISCV #BL602 Book" ... With 11 chapters of educational content ... This shall be the Book Cover 🤔

Here's how we transfer data with #BL602's UART Port

"Fifty Shades of Puns" ... I never get tired of this 😂

https://lupyuen.github.io/articles/uart#black-and-red-bitmaps

Here's how we init the #BL602 UART Port ... Yep BL602 Pins are surprisingly versatile

#BL602 UART Hardware Abstraction Layer ... High Level vs Low Level

https://lupyuen.github.io/articles/uart#bl602-uart-hardware-abstraction-layer-high-level-vs-low-level

#UART is still relevant to #RISCV #BL602 ... Even after 60 years!

#PineCone #BL602 @PINE64 talking #UART to Grove #EInk Display ... All shall be explained in this (short) article ... Thanks for watching the 24-hour #RISCV BL602 Hackathon! 🙏

Yep Grove #EInk Display doesn't need power from #PineCone #BL602 @PINE64 ... Unless we're pushing pixels to the display
