I decided to attempt to connect the PSP Screen I fumbled together earlier to the Beagle board since all the necessary signals are readily available and a display driver is included in the Ångström distro. How hard could it be ? Right ..?
Beaglebone Capes are recognized by the kernel via their eeprom. This memory holds identification and configuration data for each Cape. In order to impersonate the DVI Cape I used an ATmega32 to talk to Beagle’s I2C bus and mimicking that very specific eeprom. The actual memory contents for the DVI Cape eeprom can be downloaded from the website.
New from the fine people who have brought us the Beagle Board, we now have a smaller, lighter, but powerful single board linux computer, Beagle Bone! We like this move to a more compact and integrated SBC. For example, there is onboard Ethernet and USB host, as well as a USB client interface (a FTDI chip for shell access). It even comes preloaded with Angstrom Linux on the 4 GB microSD card!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
