首先切换到ESP-IDF下,然后利用esp-gitee-tools的脚本去更新子模块 V4.4 cd ~/sources/esp-idf/ git checkout release/v4.4 ~/sources/esp-gitee-tools/ 1. 2. 3. V5.1 sudo apt-get install python3.8-venv cd ~/sources/esp-idf/ git checkout release/v5.1 ~/sources/esp-gitee-tools/ 1. 2. 3...
We have used a similar design in that we double the functionality of the boot button to be a user button. Now I wonder about the GPIO level readings... I was under the assumption that you need to debounce every button, but the boot button seems to not bounce. Is that a feature of ...
第3步,选择ESP-IDF安装的位置,为了方便ESP-IDF工具的版本管理(因为ESP-IDF工具更新的很快),我建议大家给安装位置的文件夹标上版本号。 第4步,选择ESP-IDF工具文件夹,这里需要注意的是,末尾的.espressif最好不要改,否则可能会引起插件的错误,同样的,为了方便ESP-IDF工具的版本管理,也建议标上版本号。 第5步,指...
The light sleep is working fine and i stumpled accross the function "esp_sleep_enable_wifi_wakeup" in "the esp_sleep.h". Unfortunally there is no description of it and when I try the function out, I get as response "106 not supported". Has anyone of you successfully used this ...
GPIO12 (must be LOW during boot) GPIO15 (must be HIGH during boot) But if you are using Arduino IDE to program ESP32 board, you don’t need to set or reset the states of these pins. Because Arduino IDE sets these pins in a required state to flash code. ...
Summary esp32 boards: BUTTON_BOOT should use PULLUP instead PULLDOWN Impact Only ESP32 boards Testing ESP32-Devkitc
In recent years, there has been a strong integration of Internet of Things (IoT) technology in greenhouses, however, determining the choice between the main elements for processing the data from the sensors remains a big problem. Using an Arduino microcontroller or a Raspberry pi is a major ...
In this manner, we can connect up to 8 LCDs to the same line. There is one more thing, the ESP32 takes 7 bit address for the I2C device. All the functions, which are included in the library of ESP32 will shift this address to the left by 1 bit, 0x27<<1, and the LSB here ...

GPIO 15 (must be HIGH during boot) These are used to put the ESP32 into bootloader or flashing mode. On most development boards with built-in USB/Serial, you don’t need to worry about the state of these pins. The board puts the pins in the right state for flashing or boot mode. ...
