Voilà! Solar Panel with Touchscreen inside 😂

https://www.pine64.org/2021/08/15/introducing-the-pinenote/

Yep the Touchscreen snaps into #PineDio Stack #BL604

Underside of #PineDio Stack #BL604 @PINE64 ... I see the LCD Connector! Sorry I grazed the board (top hole) 🙏

Our Transcoder converts #Rhai Loops and Conditions to uLisp #BL602 too!

Super familiar touchscreen ... Will it connect with #PineDio Stack? 🤔

Mystery Connector at edge of #PineDio Stack #BL604 🤔

Hello #PineDio Stack #BL604 @PINE64 👋 ... Hope I don't need to unscrew the board 🤔

Secret Treasure inside Solar Panel 🤔

Solar Panel ... With a JTAG Port? 🤔

Our #Rhai Script transcoded into uLisp #BL602 runs correctly! 🎉

https://github.com/lupyuen/bl602-simulator/blob/transcode/bl602-script/src/transcode.rs#L393-L622

Now #Rhai Script is transcoded to uLisp #BL602 with the proper scopes

https://github.com/lupyuen/bl602-simulator/blob/transcode/bl602-script/src/transcode.rs#L393-L622

Let's add a #RustLang Module to manage the Nested uLisp Scopes for #BL602 ... Like "let*" and "dotimes"

https://github.com/lupyuen/bl602-simulator/blob/transcode/bl602-script/src/scope.rs

#Rhai Loops are now transcoded to uLisp #BL602 yay!

https://github.com/lupyuen/bl602-simulator/blob/transcode/bl602-script/src/transcode.rs#L279-L443

But can we connect ST7789 Display in 3-Wire, 9-bit Mode ... And pack the 9-bit data into 8-bit SPI? 🤔

Normally we connect ST7789 Display in 4-Wire Mode and transmit 8-bit data over SPI...

Our #Rhai Script to uLisp #BL602 Transcoder ... So far so good!

https://github.com/lupyuen/bl602-simulator/blob/transcode/bl602-script/src/transcode.rs#L158-L370

OK transcoding a #Rhai StackSlot to uLisp #BL602 wasn't so hard!

https://github.com/lupyuen/bl602-simulator/blob/transcode/bl602-script/src/transcode.rs#L110-L156

Transcoding #Rhai Function Calls to uLisp #BL602 ... Needs more work because of the "StackSlot" parameters 🤔

https://github.com/lupyuen/bl602-simulator/blob/transcode/bl602-script/src/transcode.rs#L107-L141

How we transcode #Rhai Statements and Expressions to uLisp for #BL602

https://github.com/lupyuen/bl602-simulator/blob/transcode/bl602-script/src/transcode.rs#L54-L105

Here's how we compile #Rhai Script to Abstract Syntax Tree ... Then walk the tree and transcode to uLisp #BL602
