Hello,
I'm testing the physical UART of my Nicla Vision board. As I did with PortentaH7, I selected Serial1 as the phisycal port, and on PortentaH7 it works. On Nicla Vision is not working.
I wrote a simple test code to toggle and I/O (pin 10 PE_13) and to print some text using Serial1.print() that I expect tx data on pin called UART_TX (PA_9).
I put on both pins a logic analyzer, I see the HIGH/LOW transitions on pin 10, but I see no output on UART_TX.
This is my code:
int pinIO = 10; //PE_13
int Counter = 0;
void setup() {
Serial1.begin(9600);
pinMode(pinIO, OUTPUT);
digitalWrite(pinIO,HIGH);
Serial1.println("Hello World!");
digitalWrite(pinIO,LOW);
}
void loop() {
delay(100);
digitalWrite(pinIO,HIGH);
Serial1.print("Count: ");
Serial1.println(Counter++);
digitalWrite(pinIO,LOW);
}
Any suggestion?
Thanks!
