venkatesh223 0 Posted April 2, 2019 Share Posted April 2, 2019 Hello there, Ive been trying to use the UART on pin number 3 and 4 by using serial for monitoring the received data and serial1 for connecting and controlling the hardware(GPS) but the by using serial1 i think the uart isnt active. i see by connecting gps to putty that there is no data sent from the cc device . I checked the hardware serial .h and .cpp file where in the cpp file there is serial1 functions mentioned but in the pins_energia file i see no pin initialized as uart only analog, timers and gpio's are initialized. So what can i do to make it work. 1 2 3 4 5 6 7 8 9 10 11 12 13 Serial1.begin(112500); Serial.begin(19200); delay(50); Serial1.println("AT"); delay(1000); Serial1.println("AT+QGNSSC?"); delay(1000); Serial1.println("AT+QGNSSC=1"); delay(1000); Serial1.println("AT+QGNSSTS?"); delay(1000); Quote Link to post Share on other sites
Shermanhig 0 Posted August 1, 2019 Share Posted August 1, 2019 I am trying to open a serial communication sending data from Arduino mega to Uno32 port1 pin 0,1. No data is transferred. I have disconnect the USB from the board and support it from power supply. I can not se the LED on Uno32 blinking. If I use port2 pin 39,40 on Uno32 the LED is blinking in the same time as the LED on mega is blinking and data is transfered. Edit: Forget this question. It was bad connection.
