Re: ESP32 with Triac

Good lords. I haven't event think about this. So my design is generally flawed. Thank You very much !

Re: ESP32 with Triac

Hey Rudy12 ! Thank You very much for your help ! <3 I am definitely going to try this ! About the Schmitt trigger input.. - I didnt knew this. With this board I am aim to manage the speed of a small ( 30W ) motor, and 1 kW heater. So. will this reflect badly on my design ? I mean - what do I need to...

ESP32 with Triac

Hello. I've spend most of this week trying to find a working code for ESP32 ( not IDF ) which would works for trigering a triac ( PWM or so ) in a meaning of regulating the output ( dimming a lamp or so ) but NO LUCK AT ALL. Most of the code I have found is about Arduino or ESP8266 with incompatible...

High voltage controller with ESP32 ?

Hello. I am not sure how to put this question, but basically I have a high voltage ( 220V ) 1 kW heater which i would like to control with ESP32, but not with a relay (i fear that too much commutations will destroy the heater), but somehow regulate it's temperature. Is it possible and how, if it is ...

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

I would like to see in the next chip :

1. additional 16 bit low noise ADC which detects very low signals ( like 5-10 mV or so ) on isolated channel.
2. separate/isolated I2C bus.
3. 32 IO free ports.

Re: ESP32 hangs on large string

ESP 32D - WROVER

I am using the original framework.

I am using WiFiServer component as a server.
anyway at some point the connection is either reset by the peer or just ESP does not respond, and my SSD1309 display freezing at this moment.

Hello. I need a ESP as a web server which provide pages which is build dynamically. Anyway it turns out that it hangs when it need to create a large strings ( as a html content and tags ). I have initially tied with WiFiServer, but it turns out that it hangs out by reason unknown, next I've tried wi...
