How to use M954B/M954C driver
1.First jump mode
you need to know which mode do you want and check device jump to the correct mode
2.Second confirm and edit transmittal mode
After your confirm your transmittal mode
Edit ax99100_sp.c code to your requirement(default is RS232)
For example if you want to test RS485 half duplex so you need to change the code uart mode
//Port1/Port2/Port3/Port4 .uart_mode= AX99100_RS485_HALF_DUPLEX,
You have 4 ports ,so you need to change code port1-port4 uart mode
3.Build driver to kernel
After edit ax99100_sp.c you can start to build AX99100 driver
#sudo make
Ends of your compiler , build driver to the kernel
#sudo insmod ax99100.ko #sudo rmmod ax99100
#sudo make install
