Ruby PCAN DLL Wrapper

Inspired by System Testing In Ruby (Systir), I have published a small Ruby PCAN USB DLL Wrapper. Now with a small device available for less than $300 and some free software, I can write automated system test scripts of the form:

send tftp_rrq("autoexec.bat").with(blksize(2036)) verify_target_sends oack(blksize(2036) send ack(0) verify_target_sends autoexec_bat send ack(1)

If you have rubygems installed, PCAN DLL Wrapper is easily obtained:

set http_proxy=http://my_proxy_host.com:80 gem install pcanusb

and then use:

require 'pcan_usb' PCAN_USB.init(PCAN_USB::BAUD_1M) PCAN_USB.write(0x0E100501, "Hello World!") PCAN_USB.close
