Sample project

(See the README.md file in the upper level 'examples' directory for more information about examples.)

This is the simplest buildable example. The example is used by command idf.py create-project that copies the project to user specified path and set it's name. For more information follow the docs page

How to use example

We encourage the users to use the example as a template for the new projects. A recommended way is to follow the instructions on a docs page.

Example folder contents

The project sample_project contains one source file in C language main.c. The file is located in folder main.

ESP-IDF projects are built using CMake. The project build configuration is contained in CMakeLists.txt files that provide set of directives and instructions describing the project's source files and targets (executable, library, or both).

Below is short explanation of remaining files in the project folder.

├── CMakeLists.txt
├── main
│   ├── CMakeLists.txt
│   └── main.c
└── README.md                  This is the file you are currently reading

Additionally, the sample project contains Makefile and component.mk files, used for the legacy Make based build system. They are not used or needed when building with CMake and idf.py.

Comandos uteis

mksppif

em: user@user/folder:~/mkspiffs$

verificar configuração do mkspiffs ./mkspiffs --version

atualmente está assim: mkspiffs ver. 0.2.3-7-gf248296 Build configuration name: esp-idf SPIFFS ver. 0.3.7-5-gf5e26c4 Extra build flags: -DSPIFFS_OBJ_META_LEN=0 -DSPIFFS_USE_MAGIC=1 -DSPIFFS_USE_MAGIC_LENGTH=0 -DSPIFFS_ALIGNED_OBJECT_INDEX_TABLES=1 -DSPIFFS_OBJ_NAME_LEN=32 SPIFFS configuration: SPIFFS_OBJ_NAME_LEN: 32 SPIFFS_OBJ_META_LEN: 0 SPIFFS_USE_MAGIC: 1 SPIFFS_USE_MAGIC_LENGTH: 0 SPIFFS_ALIGNED_OBJECT_INDEX_TABLES: 1

para alterar a configuração, tem que editar o arquivo build_all_configs.sh na pasta do mkspiffs build mksppif: ./build_all_configs.sh

gerar binário das pastas ./mkspiffs -c ../esp/Projetos/greenole/html/ -b 4096 -p 256 -s 0xf0000 spiffs.bin

flash do binario na partição esptool.py --chip esp8266 --port /dev/ttyUSB0 --baud 921600 write_flash -z 0x2DA000 spiffs.bin

compilador

na pasta: user@user/folder:~/esp/Projetos/greenole$

liberar porta usb para flash sudo chmod -R 777 /dev/ttyUSB0
compilar e gravar na esp make flash monitor
apagar a flash e suas partições, compilar e gravar na esp (necessário gravar os dados das partições após esse procedimento) make erase_flash flash monitor
exportar os path's de configuração (caso necessário pois já foram inseridos no ~~/.profile) export IDF_PATH=~~/esp/ESP8266_RTOS_SDK export PATH="$HOME/esp/xtensa-lx106-elf/bin/:$PATH"#grnl-user
