cc3200 uart pin numbers


Recommended Posts

Hi

 

Can some one help me to understand what is the pin number for Serial. port when used in BP (non-flash mode) 

The doc says it's P03 (Tx ) and P04 (Rx)  but looks like the value are showing always ZERO

 

BTW, I tried with Serial1.  and it works perfectly for the same sketch.

 

My Sketch 

 

 

 

 

 

 

 
#define LED RED_LED
 
 
char ch;
void setup()
{
  
//  Serial1.begin(9600); // Working
Serial.begin(9600);
 
  // put your setup code here, to run once:
  
}
 
void loop()
{
  // Serial1.write('A'); // Working
Serial.write('A') ; // NOT working - GPIO P03, P04 (Tx, RX)
 
  delay(1000);
  
  
  // put your main code here, to run repeatedly:
  
}
