Re: ESP32 STA configuration

Not sure. Try printing the strlen of both examples and make sure they are the same length, is where I would start.

Re: Not understanding OTA walk-through

How do you know that it didn't get updated? Not really sure what your question is. Just plug the micro usb into a wall wart power supply and the esp32 will run the app you programmed into it without being attached to your Mac. He's asking how to perform a OTA update after he changes his code and re...

Re: Run linux on the ESP32?

You'd be stretching yourself to thin in doing so, not to mention what real gain would you get by doing so.
For just a few more bucks you can get a Allwinner H2+, Quad-core Cortex-A7 that is meant to run it

Re: Best approach for button functionality

I have not dug into the docs on the ESP32 to answer that. Typically there is a register and bit in that register enable / disable and configure things like interrupt on going high, going low, or both. Gotta look into the docs to find out.

Re: Best approach for button functionality

There are many ways to skin a cat, but the way I skin mine when using a interrupt for this situation is this. Pin changes state and jumps to ISR. The first thing is disable interrupt. Set a variable to true, then clear IRQ bit to be ready for next IRQ, and exit ISR. Depending on how fast I need to c...

Re: Best approach for button functionality

There is nothing wrong with using delays, there really is no need to add hardware to filter the bounce, when you can do it all in software just the same. That snipped of Arduino code is far more than it needs to be. Also, one needs to be careful when using interrupts on buttons with no filtering. Yo...

ESP32-LyraT web radio example ?

Will there be a ESP32-LyraT web radio example ?
Just curious if they might make an example to stream audio from many of the radio stations out there.

I am glad they made this board, is very helpful to learn from.

Re: DMA to 8-bit shift register for GPIO pourposes

I might have to take another look at the FTDI controller. We tried it when it first came out. The data sheet was terrible, along with the command structure. I just never looked back at it since then. But the increase in SPI speed seems worth another lookse.
