The library can be compiled for plain Linux (for example, raspberry spi), or you can use it with plain avr-gcc compiler without Arduino IDE. It supports monochrome and RGB oleds and has debug mode, allowing to execute code on PC, using SDL2.0.

- SPI. ESP32 has 3 SPI interfaces each with up to 3 HW-controlled CS pins. One SPI is used for flash and external ROM. The basic pin positions of another one share the SD card pins, but if I'm correct then with the GPIO matrix they can be used on separate pins, so we can have SD pins, and 2 SPI interfaces.

Why, well if you at the example above the LED is connected to what would be D13 on an Arduino but if you change to either D13 or 13 in the code, the example will not work. One of the other ESP32 boards may work differently the pins_arduino.h shows how the pins are defined, for example an Arduino. #define PIN_SPI_SS (10) #define PIN_SPI_MOSI (11)

The ESP32 starts normally at first reads a few I2S and I2C reading and crashes (doesnt happen when I only use I2C). I've read on the ESP32 forums that people had some problems of the I2S messing up the reading of their I2C reads and also causing the ESP32 to crash aswell.

Oct 02, 2020 · You can test using the ESP32’s internal pull-up resistor (PULL_UP) or add a resistor to the circuit (10kΩ for example). The LED must be protected by a resistor, the value of which depends on the output voltage and current of the pin (3.3V – 40mA) and the maximum supply voltage of the LED. Takayama egg tuflite
