Arduino for STM32

I tried the tip with the leds.
In TX pin the led Blinks but it never goes off.Just change its ilumination.
In RX pin the led stays on with low ilumination.
Is this normal?

Active is low with serial.
Vcc--[1k]--|>|----RX/TX

Btw is your NEO6 5V or 3.3V??

Thanks for the tip.
My module is a 5V.

Doublecheck Rx/Tx lines (I always put 470ohm resistors in series with both rx/tx in case I messed up the wiring, btw). Also doubleckeck whether Neo6 is in binary mode (there are two modes afaik, text and binary). By the way Pito have you ever manage to make Neo-M6N to get work with STM32 board? I h...

Thanks for the interest and your help Pito.
Rx and Tx lines are OK.
But how to check if the Neo6 is in binary mode?
Also is there any way to see what i get in Serial1 port?

I get:
That means that the Serial works fine and prints everything.
But as i can understand i don't get the Serial1 (TX,RX) data to the serial monitor.

What driver do you mean?

Hi to all i am working on a project with an STM32F103C8 and a GPS Module M6N. I am using Arduino IDE and the code below: #include <TinyGPS++.h> TinyGPSPlus gps; void setup() { Serial1.begin(9600); Serial.begin(115200); } void loop() { while (Serial1.available()>0) gps.encode(Serial1.read()); unsigne...
