BL602 ADC and Temperature Sensor Library for Apache NuttX OS

This NuttX Library enables access to BL602's ADC and Internal Temperature Sensor. The code was ported from BL602 MCU SDK's ADC / GLB / EFuse Standard Driver with minimal changes...

bl_mcu_sdk/drivers/bl602_driver/std_drv

As explained in this Twitter Thread.

(Note: This library is NOT the proper way to access ADC Hardware in NuttX. Hopefully someday we will have an ADC Driver for BL602 NuttX, then we can do away with this library)

To test the BL602 ADC Library, run this NuttX App...

lupyuen/bl602_adc_test

Install Library

To add this library to your NuttX project...

cd nuttx/nuttx/libs
git submodule add https://github.com/lupyuen/bl602_adc libbl602_adc

Next update the Makefiles and Kconfig...

"Update Makefiles and Kconfig"

Change "sx1262" to "bl602_adc", preserve case
See the modified Makefiles and Kconfig

Then update the NuttX Build Config...

## TODO: Change this to the path of our "incubator-nuttx" folder
cd nuttx/nuttx

## Preserve the Build Config
cp .config ../config

## Erase the Build Config
make distclean

## For BL602: Configure the build for BL602
./tools/configure.sh bl602evb:nsh

## For ESP32: Configure the build for ESP32.
## TODO: Change "esp32-devkitc" to our ESP32 board.
./tools/configure.sh esp32-devkitc:nsh

## Restore the Build Config
cp ../config .config

## Edit the Build Config
make menuconfig
