This article introduces how to configure the serial port driver of raspberry pie. The content is very detailed. Interested friends can use it for reference. I hope it will be helpful to you.

Edit sudo nano / boot/config.txt at the end of the document and add a statement:

Dtoverlay=pi3-miniuart-bt

2. Next, we edit the document / boot/cmdline.txt with the following command:

Sudo nano / boot/cmdline.txt

Completely replace the contents of the document with the following (to delete redundant statements in the original document):

Dwc_otg.lpm_enable=0 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline fsck.repair=yes rootwait

Here we should note that the replacement is for setting up a universal serial port, which actually turns off serial console, because only in this way can the serial port become universal, that is, raspberry pie can be connected to external devices.

3 reboot

4 install pi4j and wiringpi

Offline installation: performing mirroring

Sudo dpkg-I pi4j-1.2-SNAPSHOT.deb

Install wiringpi:

Decompress: tar-zxvf wiringPi-96344ff.tar.gz

Cd wiringPi-96344ff

. / build
