Note: the Raspberry Pi runs on 3.3V so you must be sure that anything you connect to it is running 3.3V or has a level shifter. Note: make sure you don't connect a usb cable to the Arduino. You can run a simple test by putting this sketch on your Arduino: #define SERIAL_BAUD 115200Īnd wire it up using the following diagram: Could you give me some advice i could look for please.
MINICOM VS SCREEN RASPBERRY PI 3 HOW TO
Is there anything i missed? I read about 20 different tutorials and blogs on how to setup the serial port and i can't fond what causes this. Users has correct rights to access serial port: ls -l /dev/ttyAMA0Ĭrw-rw-T 1 root dialout 204, 64 Dec 25 11:53 /dev/ttyAMA0 I checked for other apps using ttyAMA0, allso nothing: ps aux | grep ttyAMA0
MINICOM VS SCREEN RASPBERRY PI 3 VERIFICATION
Verification that serial port is not used by getty anymore: ps aux | grep getty User is in dailout group so that should not be the issue(tried as root and non root): id
When checking available serial ports with python nothinig is swown: python -m _ports
MINICOM VS SCREEN RASPBERRY PI 3 OFFLINE
On the bottom of minicom it allways shows status offline: CTRL-A Z for help | 9600 8N1 | NOR | Minicom 2.6.1 | VT102 | Offline Minicom start command should be correct(tried with different baud rates): minicom -b 9600 -o -D /dev/ttyAMA0 Nothing seems to work, i'm kind of lost here. I allso tried with a python script that repeats given input. (like described in many tutorials)Īnd allso tried auto configuration scrips fromĬonnecting RX to the TX pin on rpi directly does not give any output in minicom. The settings for ttyAMA0 in files 'cmdline' and 'inittab' are ok. When failing to get a connection to the STM32F4 board, i read that you can test the serial port locally on the pi if you just connect the TX, RX pins off the pi to eachother and it should just repeat the entered data in minicom.
To setup the serial port, i followed all the stepts found in several tutorials like:
I am trying to send/receive data over serial connection (GPIO UART pins) between a Raspberry Pi (B model, raspian wheezy) and an STM32F4 board.
