Esp32 ets_delay_us. ESP-IDF It might have something to do with ESP-IDF version. Actually there is a good reason - this is both short and instructive. Delay driver Delay driver Uses the SYSTIMER peripheral internally for RISC-V devices, and the built-in Xtensa timer for Xtensa devices. h> //Requried for ets_delay_us() gpio_set_level(MY_GPIO_PIN, 0); ets_delay_us(10); //Stalls execution for #uS 用系统自带的函数: void usleep (int us); //微秒级 void ets_delay_us (uint32_t us);//微秒级 用系统寄存器计算: [可实现纳秒级延时] 孤独的程序员dis1500 esp32 延时 vTaskDelay (5000 / portTICK_PERIOD_MS); vTaskDelay (pdMS_TO_TICKS (10000)); //起作用 ets_delay_us (5); //不起作用 sp_rom_delay_us 延时函数 esp_rom_delay_us () 在 ESP-IDF 中， ets_delay_us() 函数的确已经被 esp_rom_delay_us() 替代。你可以使用 esp_rom_delay_us() 来 任务阻塞 延时 当 ESP 32与外设备连接并驱动时，一些外设的驱动时序里会涉及到 延时，因此如果在独立的任务里驱动控制外设，就需要使用到任务的阻塞 延时。 本实例将详细介 任务阻塞 延时 当 ESP 32与外设备连接并驱动时，一些外设的驱动时序里会涉及到 延时，因此如果在独立的任务里驱动控制外设，就需要使用到任务的阻塞 延时。 本实例将详细介 int esp_rom_cvt(unsigned long long val, long radix, int pad, const char *digits, char *buf) Convert an unsigned integer value to a string representation in the specified radix. See references below. c and calls IDF function ets_delay_us(us). For less time-sensitive delays I used "busy_wait_us", but the best I found for ESP is Hi, As I have observed that vTaskDelay is working on Tick Rate which gives milliseconds delay for application development but I want to prove some microseconds delay in my application. h」というファイルの中で宣言されてい Currently there are two delay providers. c:199:5: Pass esptool --no-stub to avoid this problem. /espdis Will ets_delay_us () work on core 1? Postby sramberg2 » Thu Sep 23, 2021 3:51 pm I have a task that was using ets_delay_us (), I was pinning this task to core 0 and have now moved Busy-loop CPU for the given about of us. 1c8 wuyx zdk ep9 lgd
