the purpose is to read serial data from (stm8 and s08R01 receiver) attached to /dev/ttyS01 (which is serial port on orange pi GPIO) and post it in mysqldatabase
on the raspberry pi I used /dev/ttyAMA0 -- seemed to interfere witch service : systemctl stop serial-getty@ttyAMA0systemctl (this way it stops)
one module (S08R01 (nrf24 similar on aliexpress :)) sends data to receiver module the receiver sends output to serial port of orange pi (rpi similar ;))
on the orange pi the data is stored in a mysql-database
to visualise I use http://www.ebrueggeman.com/phpgraphlib/documentation/tutorial-mysql-and-phpgraphlib
I based the script on the code from https://github.com/hubbsy/rpiGPIOserial-to-mysql.git
I installed mysql dev library : apt-get install libmysqlclient-dev
just type make after that testserial
under web directory is the php script to display data via the webserver
