Build environment: Linux (Raspberry Pi4) Moddable SDK version: 5.1.0 ESP-IDF version: 5.3.1 Target device: M5Stack Basic V2.61 Description With analogRead, the raw value range is 0 ~ 5081. Since the ESP32 is a 12-bit ADC, the maximum val...
analogSetPinAttenuation(pin, attenuation): sets the input attenuation for the specified pin. The default isADC_11db. Attenuation values are the same from previous function. adcAttachPin(pin): Attach a pin to ADC (also clears any other analog mode that could be on). Returns TRUE or FALSE r...
void analogWriteFrequency(uint8_t pin, uint32_t freq);LEDC FunctionsAlternatively, you can use the Arduino-ESP32 LEDC API. First, you need to set up an LEDC pin. You can use the ledcAttach or ledcAttachChannel functions.ledcAttachThe ledcAttach function sets up an LEDC pin with a given...
