Re: i want to map analog pins on 5volt between 0 to 1023 (10 bit resolution)

Hi, I think the simplest way to do it is with a function that makes the rule of three....
For 5v then 1024
Xv then?????

(Xv*1024)/5

Hi guys, what you build would be the same as this https://es.aliexpress.com/item/10pcs-lot-Voltage-Sensor-10pcs-for-Arduino-DC-Raspberry-Pi-Amplifier-Digital-Current-DC0-25V-with/32801635174.html?spm=a2g0s.9042311.0.0.aRy6W6 ?

Neither do I, with how easy it is with arduino IDE, for example. Last week I downloaded the 256dpi/esp-mqtt complement and it appears in the menuconfig, but I haven't tried it yet to send it to thingspeak.

Re: Simple MQTT with C++ and IDF

With the aws iot, do you have to use it on their platform or can you use the mqtt portion for another service IE: mosquitoe? Also, did you implement it in c, or C++ with the snippets aws iot code? I've done some tests with the example of espressif https://github.com/espressif/esp-idf/tree/master/ex...

Re: Simple MQTT with C++ and IDF

Hi, I have the same problem, I've tried several mqtt libraries and managed to make espmqtt work but only with C code, not C++. But I have a problem, stop sending information to Thingspeak, about 15 minutes. Therefore, I still haven't been able to use the mqtt protocol because of this, I still use RE...

Re: About temprature_sens_read();

Thanks for the answer, ESP_Sprite. No problem, I only use this value to check the chip stability, I get the temperature and humidity with I2C sensors.
