Re: Interrupts being triggered by AC Load when pull resistor is connected

ESP_Sprite wrote:10K is still on the high side: it will work but is pretty high-impedant. Suggest changing that to e.g. 1K or even 470 ohm and your problems should disappear if the AC load EMC isn't crazy-bad.
Thank you. I appreciate the help. I will try and get back to you.

Re: Interrupts being triggered by AC Load when pull resistor is connected

Fyi, a pullup or pulldown does not debounce a button, you need an extra capacitor for that. That being said, AC load triggering signals usually is because your input line is too high-impedant. What value of pullup do you use? Hi. I didn't know that we needed a capacitor too. I used the connection s...

Re: What is the meaning of startup text on ESP32

What Kolban has suggested is the best resource for all available APIs. However if it is the reset reasons that you need, there is an example code written for arduino-esp32 linked here.

Hope it helps you :)

Interrupts being triggered by AC Load when pull resistor is connected

Hello everyone. I am facing a very troubling issue here. I use a very simple code that has an interrupt attached to a button, and toggles the state of the relay when an interrupt is fired on the button. To debounce the button, I have tried using both external and also internal pulldowns/pullups The ...

How to get to know what timers are currently active?

Hey everyone. I've just started getting to know about the ESP32 and I wanted to know, Is there a way for me to know how many of the hardware timers (I believe there are 4) are currently active at a point of time? I read the API and things like esp_err_t timer_get_config(timer_group_t group_num, time...

Standalone ESP32 Module

http://i.imgur.com/p4Y2jqU.png Can the above image be used for a standalone ESP32 application, that is, can I just flash just the board as shown in the picture above, solder components to I/O pins and start using it? Or do I need to add any additional hardware apart from what is shown in the above ...
