-Cypress M8 CY4601 Family Serial Driver
-
- This driver was in most part developed by Neil "koyama" Whelchel. It
- has been improved since that previous form to support dynamic serial
- line settings and improved line handling. The driver is for the most
- part stable and has been tested on an smp machine. (dual p2)
-
- Chipsets supported under CY4601 family:
-
- CY7C63723, CY7C63742, CY7C63743, CY7C64013
-
- Devices supported:
-
- -DeLorme's USB Earthmate (SiRF Star II lp arch)
- -Cypress HID->COM RS232 adapter
-
- Note: Cypress Semiconductor claims no affiliation with the
- the hid->com device.
-
- Most devices using chipsets under the CY4601 family should
- work with the driver. As long as they stay true to the CY4601
- usbserial specification.
-
- Technical notes:
-
- The Earthmate starts out at 4800 8N1 by default... the driver will
- upon start init to this setting. usbserial core provides the rest
- of the termios settings, along with some custom termios so that the
- output is in proper format and parsable.
-
- The device can be put into sirf mode by issuing NMEA command:
- $PSRF100,<protocol>,<baud>,<databits>,<stopbits>,<parity>*CHECKSUM
- $PSRF100,0,9600,8,1,0*0C
-
- It should then be sufficient to change the port termios to match this
- to begin communicating.
-
- As far as I can tell it supports pretty much every sirf command as
- documented online available with firmware 2.31, with some unknown
- message ids.
-
- The hid->com adapter can run at a maximum baud of 115200bps. Please note
- that the device has trouble or is incapable of raising line voltage properly.
- It will be fine with null modem links, as long as you do not try to link two
- together without hacking the adapter to set the line high.
-
- The driver is smp safe. Performance with the driver is rather low when using
- it for transfering files. This is being worked on, but I would be willing to
- accept patches. An urb queue or packet buffer would likely fit the bill here.
-
- If you have any questions, problems, patches, feature requests, etc. you can
- contact me here via email:
- dignome@gmail.com
- (your problems/patches can alternately be submitted to usb-devel)
