Revision as of 23:54, 25 November 2006
Features
- for low traffic and low speed application
- mcu, RS232, RS485/RS422, slave usb all can be interchangeable.
- usb side
- support platform in linux with usb driver
- simulated uart programming in application level
- rs232 to rs485 side
- Tested max. baudrate is 115200(i assume more high baudrate can be accepted, but i have not tested)
Technical
RS232
USB
- Host Computer Setting for usb connection
- chips
RS485
- chips
- Linear Technology Corp., LTC2859 and LTC2861
- DS3695
Circuit and PCB
- gEDA Project Files, for example:
svn checkout http://chungyan5.no-ip.org/svn/open_svn/converter/trunk
- OR Download here
- gEDA libraries can be download here, then modify the gafrc inside converter/
- We have components and PCB, Or some have already soldered, if needed email to us: yan
ToDo
- get a usb chips to uart, which with linux driver
- MCT P87C52UBAA(http://pfranc.com/usb/usb.mhtml)
- cypress, PSoC with USB
- linux driver
- driver in linux : http://ftdi-usb-sio.sourceforge.net/
- usb in linux guide : http://www.linux-usb.org/USB-guide/book1.html
