Delay booting

Hello, is there a possibility to delay the boot of the ESP32. Background: With some switching power supplies the rise up time of the power is too long. So the ESP32 starts booting but does not go in normal operating mode. Wiring the GPIO0 to VCC and GPIO12 to GND helps but is not so very nice. Espec...

3.3V <-> 5V bidirectional level shifter - exampple for AM2302 (DHT22)

For connecting a 5V device on the ESP32 you should use a level shifter to protect your ESP32 (ESP32 is not 5V tolerant) There are a lot of false informations and rubbish in the net concerning this. For building a level shifter you need only 3 parts - 2 resistors and one n-channel MOSFET. Costs some ...

Is there a "deselect" function for gpio_pad_select_gpio so say that the PIN is no longer used as a GPIO ?
