In the Pin Layout section (2.1) of the datasheet, Pins 19 and 20 (SPIHD and SPIWP) of the ESP32C3-FH4 are labeled as NC (Not Connected). However, in the table in section 2.3, they are designated as default GPIOs. I tested using them as outputs, and it worked for me, but ac...

I am trying use the UART0 pins (GPIO43&44) on an ESP32-S3 board as GPIO pins. I have configured it to not use UART for the console using menuconfig and have tried Code:Select all #defineFLASH_PIN 44... gpio_reset_pin(FLASH_PIN); gpio_set_direction(FLASH_PIN, GPIO_MODE_OUTPUT)...

仅输入GPIO (Input only pins) GPIO 34 到 39 是 GPIO——仅输入引脚。这些引脚没有内部上拉或下拉电阻。它们不能用作输出,因此只能将这些引脚用作输入: GPIO 34 GPIO 35 GPIO 36 GPIO 39 电容式触摸 GPIO ESP32 有 10 个内部电容式触摸传感器。这些可以感知任何带有电荷的东西的变化,比如人类皮肤。因此,他...

关于如何创建eclipse工程,并通过eclipse下载到esp32中去(本文的工程文件在esp-idf/example/periheral文件夹中gpio工程),这里就不再详细论述了,可以看前面的文章,本文重点讲解工程源码,现在讲代码分块粘贴如下,并进行讲解。 本次操作比较简单,大致可以分为以下几个部分 ...
对于本例子的实验例子,实验操作是,将程序烧写到esp32中后,将GPIO18->GPIO4,GPIO19->GPIO5(—>表示连接),然后打开minicom(任意串口调试软件),可以看到每隔一秒gpio输出一次信息。由于app_main中第29行修改了GPIO_INPUT_IO_0为GPIO_INTR_ANYEDGE(即GPIO18的中断方式,所以,GPIO18的中断会比19多一次)。实验输出如...
