The OSX computer then displays that data in a window using CGImage. When the board receives the request, it sends its local frame buffer data over the USB connection and back to the host. The OSX computer runs a simple app that can make a request to the discovery board via USB. If it does, then the discovery board writes a copy of the data to a local buffer. The discovery board reads the address and verifies that it falls within the range of the video frame buffer. It then waits for /AS to go low, which indicates that an address is on the bus. When it sees that the R/W pin goes low, it knows that a write is occurring.

The discovery board watches the SE for writes to video memory. The discovery board acts as a USB COM port on a newer Mac OSX computer. The discovery board was then hooked up to the SE’s processor direct slot (PDS) using normal jumper wires. He ended up working out a pretty clever solution using a stm32f4discovery board.įirst, the SE’s logic board was removed from its case and placed onto a desk for easier access. He was looking for a way to view the video output from the SE on a newer, modern computer. Posted in Linux Hacks Tagged frame buffer, gui, linux If you’re eager to get down and dirty with some heavy programming, this tutorial on Linux graphics will help.

It’s something that may take some tweaking and experimentation to implement, but the hacker set rarely shy away from a challenge. It’s a project we suspect might prove useful to the developers of lightweight embedded systems. Testing thus far has been on Raspberry Pi and Beaglebone non-GUI systems, with performance varying depending on platform. Lowercase characters are currently unimplemented. In this case, a font akin to that of the Alien sentry gun interface was chosen, for an attractive sci-fi look. Glyphs are taken from an array in bitmap format, rather than font files. Working in this manner comes with some limitations.

By writing directly to the framebuffer, it would be possible to display text of a larger size without having to implement a full GUI, and overheads could be kept to a minimum. Working with a Raspberry Pi with no X server, it was found that the console text size made it difficult to display data. For these situations, wrote some code to blast text directly to the Linux framebuffer. Of course, once you start to wander off the beaten track, particularly in embedded systems with no GUI, things can get a little more difficult. Thanks to the convenience of the modern OS, we’re blessed with graphical user interfaces, where things such as buttons and windows and text are all taken care of for us.

These days, working with a display in software is fairly easy.
