How to use M954B/M954C driver
1.Jump mode
First you need to know which mode do you want and check device jump to the correct mode
2.Confirm and edit transmittal mode
After you 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
Following 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
At last make sure can test device
#ls /dev/ttyF*
4.TEST
test software:cutecom
send the word from port1(ttyF0) to port2(ttyF1)
