I have interfaced ads1256 24 bit ADC board to esp32 through SPI interface. I applied sinusoidal signal of 60Hz, 2.0Vp-p with 1.0Vdc offset using function generator to three channels(AIN0, AIN1, AIN2 w.r.t AINCOM) in Single ended mode. I used below code to read the adc input signal and the serial mon...

what is the maximum number of sensors that can be connected to ESP32?
How many analog input channels are available for connecting sensor input for ESP32 DEVKIT with 30 pin version

Can you show your source code about mqtt publish? publishing part of the code sprintf(topic, "%s%s", "/v1.6/devices/", DEVICE_LABEL); sprintf(payload, "%s", ""); // Cleans the payload sprintf(payload, "{\"%s\":", VARIABLE_LABEL1); // Adds the variable label sprintf(payload, "%s {\"value\": %s", pay...

Hello All,

We are trying to publish 7 variables from ESP32 to cloud over MQTT. We can publish upto 6 variables but still one variables is not been published. What could be the problem?

Changed MQTT packet size to 1024. But still no success.

Pls help

I need another digital pin to connect output of IR object sensor apart from GPIO23.

Hello All,

I want to connect DHT22 sensor and IR object sensor to ESP32 of 30 pin version in which both sensor outputs Digital value.
I assigned GPIO23 to DHT22 output . how can I connect IR object sensor digital output to ESP32.

Thanks in advance.
