dh8

Control software for the Diavite DH-8 surface roughness measurement device. This program works under GNU/Linux.

Building:

cd /path/to/project/root  
mkdir build && cd build  
cmake ..  
make  

Setup usb connection:

Connect the DH-8 via usb to your host-pc. The command 'dmesg | tail' shall give a similar output:

usb 7-1: new full speed USB device number 3 using uhci_hcd  
usb 7-1: New USB device found, idVendor=10c4, idProduct=ea60  
usb 7-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3  
usb 7-1: Product: CP2101 USB to UART Bridge Controller  
usb 7-1: Manufacturer: Silicon Labs  
usb 7-1: SerialNumber: 0001  
cp210x 7-1:1.0: cp210x converter detected  
usb 7-1: reset full speed USB device number 3 using uhci_hcd  
usb 7-1: cp210x converter now attached to ttyUSB0  

Check the current permissions of the created device:

ls -lha /dev/ttyUSB0  
crw-rw---T 1 root dialout 188, 0 Jan 10 09:54 /dev/ttyUSB0  

The root user and the group dialout have read/write permissions to the serial device. Make sure that your user "yourusername" is member of the group dialout:

grep dialout /etc/group  
dialout:x:20:yourusername  

If necessary add your user to the group dialout:

sudo usermod -a -G dialout yourusername  

The serial terminal configuration is:

8 data bit  
1 stop bit  
no parity  
115200 baud  

Example usage:

./src/main --dev /dev/ttyUSB0 --file ../data/20120208_surface04.m --lt 0.48 --lc 0.08
