Communicate a lcd with edison arduino using uart

Hi,

I would like to use a 4.3' inch NX4827T043 Nextion touchscreen display with edison arduino. The connection of hardware is as follow:

Nextion +5V to Edison 5V,

Nextion RX to Edison TX (Pin1),

Nextion TX to Edison RX (Pin0),

GND connected to GND

Then i uploaded a HMI which contains two numbers n0 on left, n1 on right to the Nextion Display

i compiled the code as below using Arduino IDE and uploaded to Edison Arduino.

It should alternate sending 123 and 456 between n0 and n1 on my lcd screen however i get no response. Please advice.

[code]

int i = {0};

void setup() {

Serial.begin(9600);

Serial1.begin<span class="punctuation token"...

Hi Rachel_Lim,

Thanks for your interest in the Intel® Edison™ Platform.

Unfortunately, I don't have access to a NX4827T043, so I can't replicate your issue. Looking at the details of your connection you seem to be doing it right.

I would recommend to try the mraa sample codes in order to establish a serial connection: https://github.com/intel-iot-devkit/mraa/tree/master/examples mraa/examples at master · intel-iot-devkit/mraa · GitHub .

I will be waiting for your results, have a nice day!

Best Regards,
