µTasker general / How do we re-initalise the ethernet phy

« on: July 28, 2009, 03:09:24 PM »

How do you re-initalise the ethernet connection ?

I can see that the fnTaskEthernet function creates a local instance of the ETHTABLE structure called ethernet, its loads it up then 'opens' the device returning a handle thats used from then on ...

My PHY is attached to a reset line which other IC's are attached to, occasionally we want to reset these other IC's so the PHY gets reset, not ideal. Using utasker whats the best way of re-initalising the PHY/ethernet connection with out restarting utasker.

do i just clear the Ethernet_handle and let the ethernet task re-init or ... is there away of closing an open handle?

Thanks
Carl

Hi,

I have SP4 up and running and the USB Enumerating. The debug interface works over the UART so I'm happy.

My question, whats the best way of writing a task to use this new CDC port. I've followed your utaskerUart.pdf previously to get another UART sending and receiving my own protocol. Whats the best way to do it with USB CDC Uart. So that I can control it and not have the uTaskers debug interface/menu.

Also, if i wanted to remove the uTasker Menu from all uarts (0,1 and debug) and handle the coms from my own tasks how do I do it? I Tried removing the DEMO_UART define but this doesn't compile as its required by fnSetNewSerialMode in application.c.

Thanks

Yeah having an Ethernet connection does get rid of the need for a USB connection, But not all applications need networking and you don't get PC's with serial ports anymore. So a low overhead USB CDC implementation would defiantly be useful. It saves you some money as you don't have to use a 232 to USB bridge.

Sounds Great!

Any rough idea when the USB Service pack for the SAM7 will be available?
