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

Internet outages "coincided with reports of system disruptions from Akamai and Oracle"

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

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? 🤔
