A couple of years ago it was rather fashionable to create a web server in a microcontroller, most often in a Microchip PIC 16F84. The latter has been chosen because of easy programmability, I surmise. But each implementation had at least one thing about it I disliked: One used a preprocessor to translate web page … [Read more…]

PDQt is at version 0.9 now. The issue about freezing screen on Zaurus was solved. The problem lay in too many screen updates. Aside from this issue, which concerned Qtopia binaries only, the code has been cleaned up only, without changes to the rest. The Win32 binary remained unchanged.
BeepTimer is a successful experiment in Human-Computer Interaction. The question to test was the possibility to control a device using one acceleration sensor and one button. As already mentioned, it is possible even with OS functions intervening (long button press issues a shutdown of the device). The user controls the device by tilting it and … [Read more…]
GraspForth is a simple, portable implementation of a Forth system in C. It works every 32-bit architecture GCC compiles for. The STM32 Primer devices were introduced on this blog earlier. These systems were combined in the GraspForth on STM32 Primer project. If you are interested, read the rest of the project’s description.
PDQt is at version 0.8 now. The function of the Action button was divided between the Shift button (Shift key) and the Action button (Return key). Furthermore, now PDQt recognizes circling gestures. Circling around the center of the program’s screen clockwise increases current value, circling counter-clockwise decreases it. You may download the new package for … [Read more…]
PDQt is at version 0.75 now. The key map was adapted for a usual computer keyboard; Space is the Play button now instead of C, Shift is the Action button instead of D et cetera. Furthermore, mouse wheel can be used now for changing values. Look into the help dialog for explainations. You may download … [Read more…]
PDQt is at version 0.7 now. There are no visible additions or corrections on the user side. All changes were internal. You may download the new package for Cacko and maybe other Qtopia based distributions from this page. Otherwise you might want to download the source code and compile it for yourself – you will … [Read more…]
