Hello,
I’m working on making an Arduino Mega based custom CTD.
The Arduino is programmed to send the sensor reading by serial ports to a desktop or other Arduino once a minute.
My goal is to connect the Dev kit by UART port and receive the data from the Arduino, and if possible make a simple communication to trigger the Arduino to get a sample and send it back to the Dev kit.
Here are my questions. I’m attending the workshop tomorrow and looking forward to discussing this!
- Can I use the serial_payload_example for this purpose? I don’t have much experience in embedded programming, and I couldn’t understand the difference between payload UART and UART.
- If I want to use 5V for power support, is there something I need to change on the code to enable the 5V output? There was no output when I was checking it with a multimeter.
- Should I switch the Arduino using 3.3V to connect it to the Dev kit?
