PWM Signal problems Postbyhdsjulian2»Sun Apr 21, 2024 7:26 pm On my ESP32 S2 (self created hardware design, schematic can be found here or embedded at the bottom: https://preview.redd.it/esp32s2-wont-sh ... e38d7165c4 I have, however, tested the hardware thoroguhly with a ...
PWM脉冲宽度调制 init – PWM.deinit():关闭PWM PWM.freq():无参返回当前PWM频率,有参设置PWM频率,频率范围1Hz~40MHz PWM.duty(): 无参返回当前占空比,有参设置占空比,占空比范围0~1024 PWM.duty_u16:无参返回当前占空比,有参设置占空比,占空比范围0~65535 PWM.duty_ns:无参返回当前占空比,有参设置占空比,占...
the new one is one I did with a mix of the example and another one where I should be able to send out PWM signal to pin 16. The example is running fine but when I upload the new one it's only online on the blink app for a short period. Does anyone know what's wrong? Code:...
// below. The backlight will be turned ON when tft.begin() is called, but the library // needs to know if the LEDs are ON with the pin HIGH or LOW. If the LEDs are to be // driven with a PWM signal or turned OFF/ON then this must be handled by the user // sketch. e.g...
If the LEDs are to be // driven with a PWM signal or turned OFF/ON then this must be handled by the user // sketch. e.g. with digitalWrite(TFT_BL, LOW); // #define TFT_BL 32 // LED back-light control pin // #define TFT_BACKLIGHT_ON HIGH // Level to turn ON back-light...
PWM signal PostbyAmulKetR»Mon Jun 04, 2018 9:38 am Hello, I am working on a project which used proximity detector to measure the distance from the surface. I could not find a right function that i could use in this case. There are lot of examples for a LEDcPWM but I am not ...
WDT Pin Signal TouchPad ADC DAC I2C PWM SPI UART 声明一个管脚,GPIO编号为13, 模式为输出模式 >>> pinR = machine.Pin(13, machine.Pin.OUT) 管脚写入高点平 >>> pinR.value(1) PS: 如果你手里有LED模块的话, 可以将LED模块与ESP32的13号引脚相连接, 你也可以随意指定引脚编号。

其次就是它的ble也挺有趣的，可以自己做鼠标或者键盘。这是前段时间自己做的，题主可以参考一下。
