Re: What would you like to see in The Next Chip?

A ESP32 module with onboard Ethernet PHY chip. Without the 9 RMII lines internally connected there will be 10+ lines left only to be routed outside to make the end-users' RJ45 application much easier! Na, that will increase the cost for all who dont even use Ethernet. Adding a PHY chip is ultra sim...

ESP32-S2 With LCD interface, Confused

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...

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...

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.
