ESP8266_06硬件定时器与IO中断 : 1、设置管脚4为GPIO模式 PIN_FUNC_SELECT(PERIPHS_IO_MUX_GPIO4_U,FUNC_GPIO4); 函数PIN_FUNC_SELECT的功能是选择管脚功能,第一个参数是管脚的名字,第二个参数是管脚对应的功能。 2、设置GPIO4为输入模式 GPIO_DIS_OUTPUT(GPIO_ID_PIN(4)); 3、禁止所有的IO中断智能...

I now need to upgrade to an ESP32-WROOM-32 and, to drive the motors, have delved into the latest mcpwm API. It's taken my brain cell a while to figure it out but I have successfully got the ESP32 to output exactly the PWM I needed - 16kHz PWM with 1024 steps - and I can ...
Re: Arduino ESP32 SPI output to WS2801 chip inconsistent PostbyCoder42»Thu Jan 11, 2024 3:32 pm Alright i found the source. In this project i introduced reactions to wifi sent commands. I had checked this already but forgot to disable the "wifi.begin" command. ...

My project requires 5V logic to enable the boards my ESP32 is controlling, so not having 5V at VIN will be a real pain to design around.johny_mnemonic Posts: 1 Joined: Sun Mar 12, 2023 4:52 pm Re: ESP32 VIN pin as 5V output...
ESP32是一款功能强大的微控制器,它集成了丰富的数字输入/输出引脚(GPIO),这些引脚可以作为数字信号的输入或输出,适用于各种电子项目和嵌入式系统设计。在"GPIO_output_test.zip ESP32GPIO测试"中,我们可以看到一系列与ESP32 GPIO输出功能相关的开发资源。 `.cproject`和`.project`是Eclipse IDE的配置文件,它们包含...
I want to output two PWM signals of different frequencies by esp32 with two GPIO pins GPIO 13 outputs 1kHz 50% PWM GPIO 12 output 27.7kHz 50% PWM After measurement by oscilloscope The output frequency of the two pins will be the same as 27.7 kHz How can I solve this problem? Make ...
Why do we need this ESP32_FastPWM libraryFeaturesThis hardware-based PWM library, a wrapper and enhancement around ESP32-core ledc code, enables you to use Hardware-PWM on ESP32, ESP32_S2, ESP32_S3 and ESP32_C3 boards to create and output PWM. These purely hardware-based PWM channels ...
