#mynewt

#Mynewt now officially supports #PineTime smartwatch

https://cwiki.apache.org/confluence/plugins/servlet/mobile?contentId=173087193#content/view/173087193

Apache #Mynewt 1.9.0, Apache #NimBLE 1.4.0 released

https://mynewt.apache.org/download/

#Mynewt OS has a #LoRaWAN Command-Line App that calls the Application Layer of the LoRaWAN Driver ... We shall port this app to #BL602 too
https://mynewt.apache.org/latest/tutorials/lora/lorawanapp.html

Now we port the #LoRaWAN Driver ... From Apache #Mynewt OS to #BL602

#LoRaWAN Parameters in Apache #Mynewt OS ... We shall port the LoRaWAN Driver from Mynewt to #BL602

What do #WisBlock #Arduino, #RISCV #BL602 and Apache #Mynewt OS have in common? They're using the same #LoRa driver code from Semtech! Serendipitous Discovery

https://github.com/lupyuen/bl_iot_sdk/blob/lora/customer_app/sdk_app_lora/sdk_app_lora/radio.h

#LoRa Driver for #BL602 came from Apache #Mynewt OS .... Here's how we ported the driver from Mynewt to BL602

https://lupyuen.github.io/articles/lora?8#appendix-porting-lora-driver-from-mynewt-to-bl602

Let's test the #BL602 #LoRa Driver ... With the "LoRa Ping" app ported from #Mynewt OS

https://github.com/apache/mynewt-core/blob/master/apps/loraping/src/main.c

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.

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

https://github.com/apache/mynewt-core/blob/master/hw/drivers/lora/sx1276/src/sx1276.c

"AOS" means "AliOS" ... So #BL602 IoT SDK is actually built on AliOS! But no worries ... I can port the BL602 HAL to #Mynewt ... Without AliOS

https://github.com/lupyuen/bl_iot_sdk/blob/master/customer_app/sdk_app_i2c/sdk_app_i2c/main.c#L159-L196

#BL602 #Mynewt builds OK on plain old Windows CMD (without WSL, MSYS2) ... Includes the HAL from BL602 IoT SDK yay!

Will probably test BME280 with #PineCone and #Pinenut @ThePine64 ... It's a simple sensor for Temperature, Humidity and Altitude ... And it supports both I2C and SPI. Perfect for testing I2C and SPI functions in #BL602 #Mynewt
