Test App for BL602 ADC and Temperature Sensor Library for Apache NuttX OS

This NuttX App reads BL602's Internal Temperature Sensor via ADC...

• bl602_adc_test_main.c

As explained in this Twitter Thread.

This repo depends on...

• lupyuen/bl602_adc

Install App

To add this app to your NuttX project...

cd nuttx/apps/examples
git submodule add https://github.com/lupyuen/bl602_adc_test

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 

In menuconfig, enable the BL602 ADC Test App under "Application Configuration" → "Examples".

In NuttX Shell, enter this to run the app...
