UART Communication

Hello everyone,

I connected my MKR1000 per USB to upload the code and for power supply. I also connected pins 13,14 and GND to a TTL-232R-PCB (http://www.ftdichip.com/Support/Documents/DataSheets/Cables/DS_TTL-232R_PCB.pdf) and plugged it in USB.

Then i upload the code with USB. Then i change in the Arduino IDE to the com-port of the TTL and start the Serial-monitor, but nothing happens. In a lot of posts i’ve seen that i have to use Serial1 and thats it, but it doesnt seem to help…
The TTL is fine and i also changed the usbports i use.

My program:

void setup() {
Serial1.begin(9600);
}

void loop() {
delay(100);
Serial1.println(“hoho”);
}

Can anyone help me? Have i forgot sth?

thank you in advance.

Never mind i connected TX to TX instead of TX to RX. Same for RX...
