How we init a #BL602 #ADC Channel in our C Firmware

https://lupyuen.github.io/articles/adc?3#initialise-the-adc-channel

Here's how we read the #BL602 #ADC in our C Firmware

#RustLang on #RISCV #BL602 magically transforms an LED into a Light Sensor ... All shall be explained in this article

https://lupyuen.github.io/articles/adc?1

#PineCone #BL602 Light Sensor (improvised) ... Tested OK with #Pinebook Pro @PINE64 yay! 🎉

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

#BL602 LED becomes Light Sensor ... Thanks to #RustLang ADC Firmware!

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

Building #BL602 #RustLang Firmware gets simpler ... Rust Wrapper for BL602 IoT SDK is now auto-downloaded from crates.io

https://github.com/lupyuen/bl_iot_sdk/blob/adc/customer_app/sdk_app_rust_adc/run.sh

Testing the Light Sensor on #PineCone #BL602 @PINE64 ... Actually we're reading the LED via ADC with #RustLang

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

#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!
