hspi = SPI(1, 40000000, sck=Pin(14), mosi=Pin(13), miso=Pin(12)) vspi = SPI(2, baudrate=80000000, polarity=0, phase=0, bits=8, firstbit=0, sck=Pin(18), mosi=Pin(23), miso=Pin(19)) Software SPI in ESP32 The software SPI is available on all pins of ESP32. The maximu...
For ESP32, MicroPython allows you to specify PWM frequency from 1KHz to 40 MHz. The duty cycle resolution can be from 1 bit to 16 bits. To avoid any errors in PWM generation, first determine the desired duty cycle resolution. Higher will be the duty cycle resolution, more precisely, outpu...
ESP8266 NodeMCU PWM (Pulse-Width Modulation) The ESP8266 GPIOs can be set either to output 0V or 3.3V, but they can’t output any voltages in between. However, you can output “fake” mid-level voltages using pulse‑width modulation (PWM), which is how you’ll produce varying levels...
