This example program sends repeating sequence of characters "0123456789" on
|
|
USART2 on the ST Nucleo F411RE eval board.
|
|
|
|
The sending is done in a blocking way.
|
|
|
|
Note that the Nucleo board exports the serial port as an ttyACM device on
|
|
Linux or a COM port on Windows. On Linux, if you can locate the correct
|
|
serial port as
|
|
|
|
/dev/serial/by-id/usb-STMicroelectronics_STM32_STLink_066CFF515056805087171825-if02
|
|
|
|
(note there will be differences based on the serial number of your board)
|
|
this may also show up as /dev/ttyACM0 if it was the first serial port
|
|
enumerated, if you have additional serial devices attached to the USB port
|
|
of your system they may show up as additional ttyACM1/ttyACM2/... etc.
|
|
|
|
Connect to the port using `screen /dev/ttyACM0 115200` where you replace
|
|
the serial port with the one for your system.
