Revision as of 23:22, 10 June 2008

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)

gEDA libraries can be download here or more updated, then modify the gafrc inside converter/

We have components and PCB, Or some have already soldered, if needed email to us: yan
