#BL602 #LoRa SX1262 Driver ... One last build error to be fixed ... G'nite!

https://github.com/lupyuen/bl_iot_sdk/blob/sx1262/components/3rdparty/lora-sx1262/src/sx126x-board.c

We map these #LoRa SX1262 functions to the #BL602 Hardware Abstraction Layers: GPIO, SPI and Interrupts

https://github.com/lupyuen/bl_iot_sdk/blob/sx1262/components/3rdparty/lora-sx1262/src/sx126x-board.c

#BL602 #LoRa SX1262 Driver Builds OK! Now we implement the hardware abstraction stubs for BL602

#BL602 #LoRa SX1262 Driver ... A.k.a. #Pine64 LoRa Module ... Porting in progress

https://github.com/lupyuen/bl_iot_sdk/tree/sx1262/components/3rdparty/lora-sx1262

Now porting to #BL602: Driver for #Pine64 #LoRa Module (SX1262) ... Let's see how fast we can do this 🚀

Shorter Antenna for Higher Frequency ... Because Antenna Length is Wavelength divided by 4

Straight vs Coiled #LoRa Antenna ... It's the Antenna Length that matters

The new #LoRa Module @PINE64 is based on Semtech SX1262 ... Here's the Reference Implementation of the SX1262 Driver

Pins on one edge of the #Pine64 #LoRa Module are replicated ... So it's actually Breadboard-Friendly

#LoRa Module @PINE64 with the funny PCB Trace behind ... Took me all night to figure out why 😂

Reference Implementation of Semtech #LoRaWAN Stack is here ... Includes drivers for SX1262 and SX1276

Mystery Box ... Exciting!

Add the "c_cpp_properties.json" file to #VSCode ... So that our #BL602 #LoRaWAN Build Errors are highlighted

https://github.com/lupyuen/bl_iot_sdk/blob/lorawan/.vscode/c_cpp_properties.json

Using this simpler Windows CMD script to build the #BL602 #LoRaWAN Driver ... Quicker for fixing build errors

https://github.com/lupyuen/bl_iot_sdk/blob/lorawan/customer_app/sdk_app_lorawan/run.cmd

#RustLang "cargo" Build Script can call GCC to compile C code ... Maybe we use this instead of "make" to build #BL602 IoT SDK on Windows? 🤔

https://doc.rust-lang.org/cargo/reference/build-script-examples.html

Dumping the #BL602 GCC Commands from "make" ... And running them under Windows CMD ... So much faster!

🤔

#BL602 IoT SDK build on WSL is super slow arg ... Must find a way to do native Windows build ... Without MSYS

🤔

Run #RustLang apps on #RISCV #BL602 ... With a little help from NimBLE Porting Library and bindgen?

🤔

Yearning for #RustLang on #BL602
