# ESP32 ESP-IDF and ESP8266 RTOS SDK component for 1-Wire interface ## Tested on 1. ESP8266 RTOS_SDK v3.4 2. ESP32 ESP-IDF v5.2 ## Using In an existing project, run the following command to install the component: ```text cd ../your_project/components git clone https://github.com/aZholtikov/zh_onewire.git ``` In the application, add the component: ```c #include "zh_onewire.h" ``` ## Example Search 1-Wire devices on bus: ```c #include "zh_onewire.h" void app_main(void) { esp_log_level_set("zh_onewire", ESP_LOG_NONE); uint8_t *rom = NULL; zh_onewire_init(GPIO_NUM_5); if (zh_onewire_reset() != ESP_OK) { printf("There are no 1-Wire devices available on the bus.\n"); } else { zh_onewire_search_rom_init(); for (;;) { rom = zh_onewire_search_rom_next(); if (rom == NULL) { break; } printf("Found device ROM: "); for (uint8_t i = 0; i < 8; ++i) { printf("%X ", *(rom++)); } rom -= 8; printf("\n"); } } } ``` Any [feedback](mailto:github@azholtikov.ru) will be gladly accepted.
