Integrating Web Servers | netconn APIs vs. HTTP Server Component

I'm currently using two web servers, one for wifi management and the second for firmware updates, and I need to integrate them one way or another so that I am only using one web server. I have little experience working on this topic, so I could really benefit from suggestions on which way to go. The...

Re: How to Detect Frequency (LED Status)

Thanks.. Let me know if need any help for RMT interface as we have already used it. Hello, I wanted to ask if you are familiar with the Pulse Counter? I plan to modify an example from Espressif so that I can use it for detecting the frequency on GPIOs. I am just a bit confused on how to expand on i...

Re: How to Detect Frequency (LED Status)

Hello, Which ESP32 IDF you are planning to use? So, Basically you have to use PWM or RMT interface in which you can read signals from which you can measure GPIO frequency. Hello, I am currently on ESP-IDF v4.0-dev-1346-g1b6010bed-dirty okay, thanks very much for your suggestion! I will try looking ...

Re: route (overlap) gpio to another without wiring

Thanks very much for the additional info about your example. The project requires constant monitoring of the possible GPIO states (constant ON, OFF, & 1Hz up to 5Hz) and the states of the four LEDs being monitored could change at any given time. Given the slow rates, perhaps this example may not mak...

Re: route (overlap) gpio to another without wiring

Hello, my apologies if this is a dated topic, or not exactly related to what I am asking, but I have been looking into this frequency count example, which may be useful for a project I'm working on: https://github.com/DavidAntliff/esp32-freqcount-example I'm a bit new to developing using the ESP32, ...

Re: How to Detect Frequency (LED Status)

Hello, I am just starting out with ESP32 and am looking for example code for detecting frequency on GPIOs. My ultimate goal is to be able to detect the state of (4) LEDs with possible states of: ON (not blinking), OFF, 1 Hz, 2 Hz, 5 Hz -- basically detect the status and print to screen or collect t...

Re: How to Detect Frequency (LED Status)

Let's start our problem description by defining the conditions. What are the LEDs connected to? More specifically, is your ESP32 powering (controlling) the LEDs? If not, how are the LEDs being powered? And is it safe to assume these are like just generic single-color LEDs in series with a ~220 (ish...

Re: Wifi Configuration (SSID & Password) Over HTTP Web server

thanks very much for the suggestion... also, I just found this example, which is also good:

https://github.com/tonyp7/esp32-wifi-manager

The only thing missing is the functionality of changing the ESP's access point credentials from the web server.
