4 Quick Start
4.1 Build
$ sudo apt-get install git wget make libncurses-dev flex bison gperf python python-serial $ wget https://dl.espressif.com/dl/xtensa-esp32-elf-linux32-1.22.0-59.tar.gz $ mkdir -p toolchain $ tar zxf xtensa-esp32-elf-linux32-1.22.0-59.tar.gz -C toolchain $ export PATH=$PATH:`pwd`/toolchain/xtensa-esp32-elf/bin $ $ git clone --recursive git://github.com/icamgo/esp-idf.git $ export IDF_PATH=`pwd`/esp-idf $ cd esp-idf/examples/09_adc_read $ make menuconfig $ make -j2
4.2 Connections
To test the ADC pin of ESP32 on Quantum:
- Connect the Quantum_IO35 to 3V3 (measure the power voltage)
- Connect the Quantum_IO34 to GND (measure the GND voltage)
- Connect the Quantum_IO36 to GND
4.3 Upload
$ make flash
You need to press the RST buttom after uploading the firmware into flash. If you guys do not like to do this please patch the /path/to/esp-idf/components/esptool_py/esptool/esptool.py :
