#BL602 ADC Firmware in #RustLang ... Looks similar to C except for the "unsafe" parts

https://github.com/lupyuen/bl_iot_sdk/blob/adc/customer_app/sdk_app_rust_adc/rust/src/lib.rs#L39-L100

String Formatting in #BL602 #RustLang ... Yep safer than "sprintf"

https://github.com/lupyuen/bl_iot_sdk/blob/adc/customer_app/sdk_app_rust_adc/rust/src/lib.rs#L102-L165

Copying data from a C Pointer is unsafe, #RustLang reminds us

https://github.com/lupyuen/bl_iot_sdk/blob/adc/customer_app/sdk_app_rust_adc/rust/src/lib.rs#L102-L165

Here's the #RustLang code to read data from a #BL602 ADC Channel ... And compute the average

https://github.com/lupyuen/bl_iot_sdk/blob/adc/customer_app/sdk_app_rust_adc/rust/src/lib.rs#L102-L165

#RustLang reminds us to be Extra Careful when Casting C Pointers ... Because it's unsafe and can go horribly wrong

https://github.com/lupyuen/bl_iot_sdk/blob/adc/customer_app/sdk_app_rust_adc/rust/src/lib.rs#L39-L100

How we init a #BL602 ADC Channel in #RustLang

https://github.com/lupyuen/bl_iot_sdk/blob/adc/customer_app/sdk_app_rust_adc/rust/src/lib.rs#L39-L100

Here's how we call the #BL602 #RustLang Wrapper for GPIO

https://github.com/lupyuen/bl_iot_sdk/blob/adc/customer_app/sdk_app_rust_gpio/rust/src/lib.rs

#RustLang Wrapper for #BL602 IoT SDK ... Now on crates.io ! 🎉

https://crates.io/crates/bl602-sdk

See the redundant "gpio" in our #BL602 #RustLang Wrapper Names? Let's remove them

https://lupyuen.github.io/bl602-rust-wrapper/

Added DMA #RustLang Wrappers for #BL602 IoT SDK ... Because ADC needs DMA

https://lupyuen.github.io/bl602-rust-wrapper/

Thanks to our #BL602 ADC Experiment ... We now have docs for our #RustLang Wrappers for ADC!

Here's the right way to set #BL602 ADC Gain ... By calling the BL602 ADC Standard Driver

https://github.com/lupyuen/bl_iot_sdk/blob/adc/customer_app/sdk_app_adc2/sdk_app_adc2/demo.c#L114-L142

Remember this awful hack for setting the #BL602 ADC Gain? Let's do this The Right Way with the ADC Low Level HAL

https://github.com/lupyuen/bl_iot_sdk/blob/adc/components/hal_drv/bl602_hal/bl_adc.c#L339-L367

Here's how we average the ADC Samples with the #BL602 ADC Low Level HAL

https://github.com/lupyuen/bl_iot_sdk/blob/adc/customer_app/sdk_app_adc2/sdk_app_adc2/demo.c#L68-L104

Sadly #BL602 ADC High Level HAL won't let us average the ADC Samples ... So we rewrite our firmware to call ADC Low Level HAL instead

#PineTime v2 🤩

Why does our #BL602 Light Sensor work only in Sunlight? I'm guessing: 1️⃣ Because our LED is Blue 2️⃣ Sunlight is intense (especially in Singapore)

Need to enable ADC Gain when reading the #BL602 LED ... By modding the BL602 ADC HAL source code 🙄

https://github.com/lupyuen/bl_iot_sdk/blob/adc/components/hal_drv/bl602_hal/bl_adc.c#L339-L367

Yep #PineCone #BL602's Blue LED works as a Light Sensor (I think) ... But only in Sunlight 🤔

https://github.com/lupyuen/bl_iot_sdk/blob/adc/customer_app/sdk_app_adc/sdk_app_adc/demo.c

Can we turn #PineCone #BL602's LED into a Light Sensor ... By reading it with ADC? 🤔
