Instructions (control via ap)
+
[[Image:F81534_set_mode.JPG]]
-
We also provide demo application to control mode changing. All following operation should work with root
+
-
privilege.
+
-
• set_mode.c
+
-
◦ Control F81532/534 internal RTS operation mode.
+
-
◦ Using Linux RS485 ioctl TIOCGRS485/TIOCSRS485 to get/set mode.
+
-
• set_gpio.c
+
-
◦ Control F81532/534 M0/M1/M2 output only pin to control target transceiver per port.
+
-
◦ Auto-detect sysfs or gpiolib to control F81532/534
+
-
Build demo application
+
-
• change to demo application folder.
+
-
• make clean ; make
+
-
• you'll get set_mode & set_gpio in the same folder.

How to Install F81534 driver

Fintek F81534 driver install

1.Prepare the kernel tree & compiler tools for your distribution. 

    #sudo su
    #apt-get update
    #apt-get install build-essential gcc

2.unzip driver zip file (F81534-532_DriverSourceCode-<version>_Linux.zip)

  1. cd F81534
  2. make clean ; make ; make install
  3. modprobe usbserial
  4. rmmod f81534 ; insmod f81534.ko

3.check new port added by “dmesg | grep ttyUSB”.

  1. reboot

How to use F81534-change Mode

1.unzip tool zip file

  1. make clean ; make
  2. you'll get set_mode&set_gpio in the same folder

2.Using demo application

3.Example

1. Change ttyUSB3 to RS232 Mode

  1. ./set_mode ttyUSB3 1
  2. ./set_gpio ttyUSB3 1

2. Change ttyUSB3 to RS485 Mode

  1. ./set_mode ttyUSB3 2
  2. ./set_gpio ttyUSB3 2

3. Change ttyUSB3 to RS422 Mode

  1. UART Mode is don’t care.
  2. ./set_gpio ttyUSB3 0

Notice:


RS485_1 / RS422_Term / RS232_coexist / RS485_Term / Shutdown mode are not test yet.(EVB)


Only test RS422(EVB)/RS232(EVB)/RS485(EVB).
