Recently I came through the need to access data in some equipment using some fancy mobile device. Normally, a laptop would be connected to the equipment using a serial cable and data extracted through the file dumping capabilities of Hyperterminal. This is a pretty standard situations to retrieve data from some equipment as, even nowadays, serial ports are pretty common on certain domains.

In part II (http://papermint-designs.com/community/node/338) I explored the contents of our cape EEPROM. This time I will show how I physically built the NULLCape...

In Part I (http://papermint-designs.com/community/node/331) we discussed how to attach an EEPROM to our cape. Now we will see how to fill the EEPROM with useful data.
We've already seen how to write data in our EEPROM (see http://papermint-designs.com/community/node/331). Now, we need to know which data we have to write. That's easy, cape EEPROMs have to follow the format described in the System Reference Manual. Specifically in section 8.2.4 EEPROM Data Format.

We want to learn how to build BegleBone capes and in this series of post we will be writing about our findings and how we built the NULLCape. You are right, that is the very minimum cape which actually does nothing.
Good question. Yes, sure you already now, but just in case you are really, really new to the BeagleBone or you've got yours as a present you had never ever hear of it.
A cape is just an expansion board for the BeagleBone. The BeagleBone provides two headers on its sides with lots of signals and interfaces, however you normally need something else to be able to attach your peripherals to this connectors. In the simpler case some wires and a platform to mechanically keep your peripheral and in the most complex case some support circuitry in order to do whatever you want to do.
Reading for the weekend... a bit late this time.

The usual links to have fun during the weekend (BeableBone, Raspberry Pi, Arduino,...). I never manage to do anything with them, but maybe you can.
Have you ever thought about building your own phone?... I have and these are some links with interesting projects others had already made.
