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...

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...

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.

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.

Thank you for the great reply. I worked for this company years ago, and wrote the graphics lib, and designed the board for them years ago. http://www.versamodule.com/Video/VM7/VM7.html On that board I am using a RA8875 graphics controller. It has both spi and parallel interfaces. As i am sure you al...

Much of what I do involves using LCD's. Sadly I have put off learning how to use DMA. I saw this great post by ESP_Sprite: https://esp32.com/viewtopic.php?f=17&t=3188 , that got me thinking... It seems to me this is the only way to go for LCD's is to have the processor update the screen in the backg...

@Kolban. I understand you point of view. Still curious as to the "why" there is not more OTA examples is all. IMHO if you are a company that makes a Wi-Fi product you second focus would be to update it OTA.

@kolban, if i can play devils advocate. Even with OTA running, and it crashes you still have serial available. I don't know if this idea is even possible yet as still very new to this platform. Coulden't one use OTA1 as say a boot mode for the getting the Wi-Fi connected, and OTA running. Once that ...

Hello guys! Started playing with ESP32 last week. Just loving it so far. Concerning ESP-IDF OTA, I am a bit puzzled why the OTA demo folder has just one example in it which is to connect to a server to get its .bin file. This does not seem like the most common use case for the average user starting ...
