system from https://dl.altera.com/?edition=web Please make sure you download
vesion 13.1 as newer versions don't support the Cyclone III FPGA anymore.
Once installed Quartus will allow you to import the [led.qar](https://github.com/mist-devel/mist-board/raw/master/tutorials/led/led.qar) archive.
Once installed Quartus will allow you to import the [led.qar](https://github.com/mist-devel/mist-board/raw/master/tutorials/led/led.qar) archive. Use the qar import by selecting "Restore Archived Project..." from the "Project" menu.
Selecting "Start Compilation" from the Processing menu will create the led.rbf
Selecting "Start Compilation" from the "Processing" menu will create the led.rbf
file. Putting this under the name "core.rbf" on sd card and booting the
mist from that card should result in the FPGA led blinking once a second.

Using signaltap
---------------
Signaltap is a very useful tool when developing cores. It allows you to observe
signals directly on the running FPGA.
You need a cheap usb blaster cable to use this feature. Searching for "usb blaster"
on ebay or amazon should give plenty of matching results.
The blaster cable is connected to the PC via USB. For more information see the
[Wiki](https://github.com/mist-devel/mist-board/wiki/UsingAByteBlaster). You also
need to add a matching connector to your MIST board. Althoug the board is prepared
for this connector you still need to get it soldered to the board.
