use its 5V power rail port to connect the sensor's VCC power supply?

Yes, but what voltage is your sensors output voltage? If 5v as well you have to bring that down to 3.3v.

Just downloaded it. Didn't flag it as a threat this time.

Can you set both GPIO 16 & 17 as inputs. then use a couple jumper wires from GPIO 1 & GPIO3 to 16 & 17.

Basically pair up TXD0/RXD0 with U2TXD/U2RXD, to prove the connections. Then whatever you send out through the default terminal pins will come out on your DB-9 connector.

I connected "+" to 3V3 and "-" to GND pin and nothing happens. Battery has been charged to full capacity and voltmeter shows me around 3.44V.

Why would you connect a higher voltage to a 3.3v supply pin ?

Windows immediately popped up with a virus threat!

If memory serves when you have a GPIO pin configured as an output, when you try to read the pin it does not read the actual I/O pin state. Try this. static void i2c_0_task( void *pvParameters ) { // initialize the xLastWakeTime variable with the current time. TickType_t xLastWakeTime = xTaskGetTickC...

Ran your question an example if MCPWM can be used as a normal PWM signal? through AI, and this is what It shot back. Yes, you can use the MCPWM module to control a LED via PWM on the ESP32, even though MCPWM is typically used for motor control. When controlling a LED, you typically only care about g...

it is in the docs.

the error mainly comes from the quartz oscillator block, when removing the module cover and touching the quartz pins, the module starts again Why would you remove the module cover ? Touching any products crystal pins will result in the same. this error often appears when the weather turns cold, The...

We really have no upgrade path with Espressif today... I hate to admit it, but I agree. They upgrade one thing and remove another. It's slowly been turning into a Hodgepodge of micros. The P4 had the best shot at having everything until they removed the WiFi. :roll: I say just throw it all in one c...
