Workaround for poor WiFi connection after update ESP32-xx LittleFS builds in this release are now using ESP-IDF 5.4.1 Espressif made some significant changes in the WiFi code. This means the existing WiFi RF calibration data may not be compatible with new RF calibration data in ESP-IDF >=...
想用ESP32驱动步进电机(开环,无编码器),需要精确控制PWM的脉冲个数,看了下datasheet是有高/低速时钟计数器达到最大计数值触发中断的功能,但是看了下LEDC的API:esp_err_tledc_isr_register(void (*fn)(void *), void *arg, int intr_alloc_flags, ledc_isr_handle_t *handle ),不知道该怎么用:1.比如...
There has been a lot of excitement around greenhouse automation systems and their potential to improve growing conditions and yield. This project describes how to build a Greenhouse Automation System using an ESP32 WiFi Board, an AM2301 humidity and temperature sensor, an Actuator Relay Module for...
This project is improved on the basis of the original open source, using ESP32s3 as the main control, with WiFi Bluetooth function, and users can also develop servers for remote control. The ESP32-S3 mini drone can be connected and controlled through a Wi Fi network using a mobile app or...
