Chromebooks Bricked: "instead of "&&"—the C++ version of the "AND" operator—the bad update used a single ampersand, breaking the second half of the conditional statement"

SpaceX Starlink Review - Four months in

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
