Particle Boron LTE + Adafruit Huzzah32/ESP32 - Serial/UART

[ScruffR]

Welcome to the community.
What you are looking for is doable and it wouldn't matter whether you are talking to a ESP32 or another Particle device. As long as both sides don't exceed the voltage limit of the respectively other you can connect any micro with any other via UART.

Having said that, have you searched the forum before posting as this is a rather common question?
This would be a tip stated in this Forum Etiquette post.

Transmitting two separate encoder values between two photons using Serial1

Hello! I am using two optical encoders attached to stepper motors in order to determine the orientation of a rotating object. One photon is being used to receive the encoder data and transmit it to the second photon. The second photon will then process both encoder’s data. I would like help sending over both sets of encoder step data (integer values from 0 - 500) using the Tx and Rx pins. So far, the receiver photon only receives the encoder values 0 - 255, resets back to 0, and starts again. …

[Solved] Serial communication with an arduino

Following these threads: Spark (3.3v) to Arduino (5v) Serial Communication ,Arduino serial communication to Spark Core, I tried to send data from an analog sensor from an Arduino to a Spark via Logic Level Converter. Without any success. [image] My Arduino code is const int analogPin = A0; void setup() { Serial.begin(9600); pinMode(analogPin, INPUT); int sensor =0 ; } void loop(){ int sensor = analogRead(analogPin) ; Serial.println(sensor); delay (1000); } My Spark code …
