ESP32-S2 With LCD interface, Confused

I was looking into the new ESP32-S2, primary because it says this: With LCD interface and 14 configurable capacitive touch GPIOs, ESP32-S2 provides the optimal HMI solution for touchscreen and touchpad-based devices. From this Link: https://www.espressif.com/en/products/socs/esp32-s2 I was looking a...

Re: ESP32: Use Arduino or ESP-IDF?

In short, I can't express how frustrated I am with Arduino, and how great ESP-IDF has been. Simular issues here. I started out with Arduino only because I was new to espressif. As time moved on and I started moving on from simple hello world, toggling GPIO and so on to adding peripherals and making...

Try sticking a delay(10); or delay(100); in your loop().

Re: ESP32 DEVKIT and 12V NPN Sensor

What voltage is sensors output ?
If it's 5v you have a problem. You need to get it to 3.3v.

Re: Is my Schematic Ok?

This is the one we use in all of our products.
Not sure what you Vin requirements are, so there are 2 of them.

Re: ESP32: Use Arduino or ESP-IDF?

You can leave it the way you posted it, its just fine. I will mention this though. concerning blink.c. You might want to consider moving these to into main.c, before you do anything else. I would also add after these, gpio_set_level(BLINK_GPIO, 0); with either a 0 or a one to set the pin state to wh...

You dont get all the extra flexibility from menuconfig to do enhancements and fine tuning.

Re: Can someone explain my oscillating touch readings?

It radiated energy from everything around you. Lights, power supplies and so on. You body is an antenna that picks up this noise.
You can think of it if you ever dealt with audio amplifiers and touched the input cable while it was plugged in and head that typical "hum" noise.

Re: Esp Now distance.

I don't know if there is another solution in software to help. I do remember seeing a way to change the output power. But I don't know if by default its set to the highest level. I would also look into using the ESP32 module with the U.FL (IPEX) CONNECTOR on it. https://www.gridconnect.com/products/...

Re: Upload code without pressing EN and Boot buttons

I never used a ESP8266. Just head over to espressif web site and download the schematic for it to see.
