MicroLisp Interpreter, I2C, SPI, WiFi and Graphics ... All in a single C source file amazing 🤔
https://github.com/technoblogy/ulisp-esp/blob/master/ulisp-esp.ino
Maybe we wrap up the #MicroLisp code in a graphical program like Scratch / Blockly? 🤔

#uLisp Interpreter on #RISCV #BL602 brings back memories 🥲 ... Let's do uLisp Blinky next!
https://github.com/lupyuen/bl_iot_sdk/tree/ulisp/customer_app/sdk_app_ulisp
Why are they called CAR and CDR in #Lisp? Here's why
#Lisp is Not Dead Yet! We still see bits of Lisp today in #WebAssembly ... Like the Stack Machine and S-Expressions

How we modded #uLisp to call #BL602 GPIO Hardware Abstraction Layer
https://github.com/lupyuen/ulisp-bl602/blob/master/src/ulisp.c#L3536-L3554
Let's run this #uLisp Blinky Function on #BL602
https://github.com/lupyuen/bl_iot_sdk/tree/ulisp/customer_app/sdk_app_ulisp
Previously we've done a #Blockly Code Generator for Embedded #RustLang ... But it got complicated because of Type Inference ... Lisp should be simpler, I think 🤔
https://lupyuen.github.io/articles/advanced-topics-for-visual-embedded-rust-programming
Let's use this #Blockly Demo ... And add a "Lisp" tab to show our Generated #BL602 #uLisp Code
https://github.com/AppKaki/blockly-ulisp/blob/master/demos/code/index.html#L26-L41
Drag-n-drop #BL602 #uLisp Blinky with these blocks ... Code Generator coming soon ... Try it for yourself here: https://appkaki.github.io/blockly-ulisp/demos/code/
Can we transfer the generated #uLisp Script to #BL602 over Web Serial API? 🤔
https://dev.to/unjavascripter/the-amazing-powers-of-the-web-web-serial-api-3ilc
Yep Web Serial API works with #BL602 at 2 Mbps ... Soon we shall transfer some uLisp Scripts ... From Blocky (Scratch) to BL602!
Cool new way to run #BL602 firmware without putty and CoolTerm ... Just use Web Serial Terminal!

Sending the "reboot" command to #BL602 from a Web Browser ... Via Web Serial API

Proper way to send #BL602 the "reboot" command ... From Web Browser with Web Serial API
How we build and flash the #uLisp Firmware for #BL602

@lupyuen
Thats the future of programming.
@lupyuen Congratulations!
@lupyuen I might have some insight into the SX1276? issue. It just occurred to me what to do.
Try using sudo and lsusb -v to measure the power being allocated to the BL602 board. I had readings of 98mA. An ammeter would work too. I don't think it's getting the power to emit more radiation.
@AmpBenzScientist Interesting... so we think BL602 might not have sufficient power for the LoRa Module?
Here's what I observed...
(1) BL602 + SX1276 seems to be emitting the right power (see the red chirp)...
https://lupyuen.github.io/articles/lora#visualise-lora-with-software-defined-radio
(2) But BL602 + SX1262 seems to be emitting much less power (the faint chirp)...
https://lupyuen.github.io/articles/lorawan#troubleshoot-lorawan
If it's a power problem, why is SX1262 affected but not SX1276 🤔
@lupyuen@qoto.org Doesn't work for me like the idea though
@lupyuen@qoto.org might be brave adblocking being weird but nothing happened clicking the play button
@Nonetrix Yep the button doesn't do anything ... Since we don't have an emulator
@lupyuen@qoto.org oh could you use wasm for that I guess but probably would be best to do something in JS
@Nonetrix maybe that button should transmit the uLisp script to BL602 over Web Serial API 🤔
@lupyuen@qoto.org what's that I'm not very familiar with open hardware stuff if that's what it is
@Nonetrix Makecode for BBC micro:bit has an emulator in the web browser, check it out here:
#Blockly (Scratch) needs a Code Generator for each language ... So we copy the Dart generator, paste it as Lisp ... And tweak the Lisp generator for #BL602 🛠️
