Hi µTasker users!

This is a µTasker users message to inform of the following new items.

1. Olimex offers a low cost evaluation kit for the AT91SAM7X (http://www.olimex.com/). It took a long time for an alternative to the ATMEL Eval board to arrive but it is now available and selling for USD 115.95. It has a colour LCD, audio, CAN, USB and Ethernet 10/100.

And the news is that it is supported by the µTasker. Many thanks for Sebastian in Poland for confirming that the µTasker project is working there (Ethernet and UART support). The demo project does need a new define for the board and a few simple mods (it uses a MICREL PHY rather than the DAVICOM on the ATMEL board) but if anyone wants them just ask me. I may get them on the Internet soon as well...

2. The demand for extended use of the general purpose ports on the M5223X has been high and I have decided that rather than try to individually help several users to get extended use into their projects it would be worth while adding it to the project code. So this is what I have done and it is available for download by all users of the M5223X package V1.2.007.

Get the kit from http://www.utasker.com/software/M5223X/V1.2.007_port_update_kit.zip

This contains just the files which have been modified and it can be extracted directly to the demo project directory if you want - just overwrite the files which are extracted. If you have made your own changes in the demo project be careful that nothing important is overwritten though.

It adds the following and the I/O web page should be loaded to the FTP server to be able to use 16 user definable outputs:

- The project will initialise 16 user definable ports as outputs and set their states according to a parameter value (preserved over reset and power cycle if desired).

- The new web page displays the 16 port state as a key pad with grey meaning that the state is "0" or off, or red when the state is "1" or on.

- Clicking on keys will toggle the port states. The present state can be saved as default if desired.

- The realisation of the user definable ports is of a generic nature so they can be defined to be on any hardware port and at any bit position (mapping). This takes place in application.h where you can set each of the 16 outputs to both a port and a bit and the code will not need any further information to get it all right.

- Finally the port simulator has been expanded to include all ports in the M5223X enabling the project to be fully tested using the simulator. Try mapping to other ports and bits as desired and see it happen...

I hope that you find these bits of information useful and do try out the M5223X upgrade kit if you would like to use more GPIOs. Should you require any more detail just mail me!!

Good luck.

Regards

Mark
